Results – PNA-X Case Studies Challenges This customer manufacturers over 4600 RF components, with typically 100 0 devices in the manufacturing process at any given time. Devices included ilters, mul tipliers, ampliiers, and switches, from 10 MHz to 60 GHz. They needed to simplify the test system for one particular multiport device, so they set out to develop an opera tor- independent automated test system (ATS). Key challenges included: – Complicated and expensive test systems with multiple racks of equipment and miles of test cables – Multiple cable swaps and recalibrations required with extensive operator intervention and downtime –Signiicant retesting of devices and high system downtime Results The PNA-X’s ability to incorporate more active measurements into a singl e instrument than any other product on the market provided: – Faster test times: Reduced test times from four hours per temperature to 24 minutes when compared to the prior ATS, resulting in a test-time reduction of 95% – Reduced equipment count: Replaced nine racks of equipment with three, 12-port PNA-X network analyzers – Increased operator productivity: Enabled operators to monitor four test stations simultaneously and eliminated the need for single-operator test stat ions – Reduced re-testing and cable swaps Case Study 1 Aerospace/defense component supplier reduces test time by 95% Challenges This aerospace company was conducting a speciic panel-level test and want ed to modernize its test systems and improve its test productivity and throughpu t. Its legacy satellite payload test systems utilized a large amount of rack an d stack equipment accompanied by a big test overhead. The company was required to exert a great deal of time and effort to program and maintain the test systems. Results Initially the aerospace company purchased four PNA-Xs (26.5 and 50 GHz mod - els). They were so impressed with the throughput and test productivity results , that they purchased eight more analyzers. In one test case, the level of improve - ment exceeded expectations—taking a 20-minute gain-transfer test t o just under a minute. Replacing their test system with the PNA-X effectively modern ized and simpliied their test system which enabled: – Faster test times: Complete test suite cut measurement times from three hours to three minutes – Reduced equipment count: Replaced a two-rack payload test system with a single four-port PNA-X – Smaller test system: Reduced the amount of equipment space and power consumption Case Study 2 Satellite designer and manufacturer reduces test time from three hours to three minutes Test Engineering Manager 04 | Keysight | PNA-X Series Microwave Network Analyzers - Brochure
The manufacturer was developing a new broadband wireless network system a nd needed a faster test system. Its existing test system consisted of two sourc es, a spectrum analyzer, and power meters. Using this system, they estimated t heir new product would take 30 minutes to test; however their speed goal was 15 minutes. In addition to needing a faster test solution, the company also needed better n oise igure and distortion measurements, and it required single-connection me asure- ments on both up and down converters. Results Replacing their existing multi-instrument test system with a single four -port
50 GHz PNA-X enabled the company to realize:
– Faster test times: Complete test suite cut test throughput from an estimated 30 minutes to under ten minutes – Less downtime and reduced maintenance costs: Reducing the equipment count reduced the setup time, as well as the headaches associated with multiple equipment faults, and resulted in lowered annual calibration cost s – Cost savings on equipment: The cost of a four-port PNA-X was substantially less expensive than the legacy multi-instrument test system. Case Study 3 Wireless networking systems manufacturer reduces throughput from 30 to 10 minutes Challenges The company needed to upgrade its legacy test systems, which consisted of lar ge switch matrices with network analyzers. They required technicians to ke ep connect- ing and disconnecting the device-under-test (DUT) to multiple instrumen ts to make a range of different measurements. This approach was slow, costly, prone t o inac- curacy, and required a good deal of user intervention and additional hardwa re. The company sought a solution that was easy to set up and use, decreased test time and cost, minimized measurement inaccuracy, and offered a smaller footpri nt Results The company decided to purchase PNA-Xs rather than simply upgrade to newer, code-compatible, drop-in instruments offered by the provider of its lega cy test equipment. This decision was made despite the fact that it meant signiican t rewrite of legacy software. The company saved time over their existing test soluti ons and realized: – Easy setup and use: Technicians were able to easily connect to a DUT and measure all different parameters in one pass—without additional hard ware – Faster and more accurate tests: Using just one instrument technicians were able to conduct their required tests in signiicantly less time and improve accurac y – Smaller test system: A single four-port PNA-X reduced their initial capital expense, equipment count, loor space, and power consumption, which resulte d in lower overall test costs Case Study 4 Global security company speeds test and improves measurement accuracy Test Engineering Manager 05 | Keysight | PNA-X Series Microwave Network Analyzers - Brochure

Pulsed-RF measurement challenges – Pulse generators and modulators required for pulsed-RF measurements add complexity in test setups –For narrow pulses: – Maximum IF bandwidth of analyzer is often too small for wideband detection – Narrowband detection is slow, and measurements are noisy for low-duty-cycle pulses PNA-X pulsed-RF measurements provide: – A simple user interface for full control of two internal pulse modulators (Option 021 and 022), and four internal independent pulse generators (Option 025) –Point-in-pulse measurements with 20 ns minimum pulse width, and pulse proil e measurements with 10 ns minimum resolution (Option 008) – Improved measurement speed and accuracy for narrowband detection using hardware ilters and patented spectral-nulling and software IF-gati ng techniques – Measurements using wideband detection with pulse widths as narrow as 100 ns – Pulse I/O connector on rear panel for synchronization with external equipment and DUT – Accurate active-component characterization using unique application measurement classes for gain compression, swept-frequency/power IMD, and noise igure Pulsed-RF measurement application automatically optimizes inter nal hardware coniguration for speciied pulse conditions to dramatical ly simplify test setups. Alternately, users can choose to manually set up th e hardware for unique test requirements. Pulse proile measurement using narrowband detection technique all ows 30 measurement points within 300 ns pulse, with 10 ns timing resolution. Providing the irst one-box pulsed-RF test system, the PNA-X sets a new standard for simplicity, speed, and accuracy. By the 1990s, the HP 8510 was the industry- standard for pulsed-RF vector network analyzers. The PNA Series replaced the pulsed 8510 with a bench-top solution. Innovative
Applications
Simple, fast and accurate pulsed-RF measurements (Options 008, 021, 022, 025) 10 | Keysight | PNA-X Series Microwave Network Analyzers - Brochure
PNA-X’s narrowband detection method used for narrow pulse widths (< 267 ns) employs special hardware and patented software-gating techniques to improve system dynamic range for low-duty-cycle measurements by 40 dB compared to PNA-based pulsed-RF systems. Using receiver leveling improves the pulsed-RF power accuracy from +/- 1 dB to less than 0.05 dB. Above measurements compare the results with and without receiver leveling in GCA measurements. Inaccurate stimulus causes large erro rs in power-dependent measurements such as input and output power at the compression point versus frequency. The PNA-X accurately characterizes active devices under pulsed oper ation with a single set of connections to the DUT—pulsed S-parameters, pulse proile (input and output power in the time domain), gain compression versus frequency, and swept-frequency IMD are measured in this exampl e. Tips from the experts – Compared to sweep averaging, point averaging typically provides faster results when averaging is needed to lower noise and improve accuracy of measurements using wide- band detection. – During source power calibrations, power sensors read the average power, while the analyzer sets the peak power of the pulsed stimulus. To compensate for the difference between the peak and average power, use the power offset feature with the value of 10 log (duty cycle). – The minimum pulse width for point-in-pulse measurements using wideband detection is determined by the number of samples required for the IF bandwidth (IFBW). For example, the minimum pulse width is 100 ns with 15 MHz IFBW, 300 ns with 5 MHz IFBW, and 1.44 μs with 1 MHz IFBW. When working at the minimum pulse width for a particular IFBW, it is important to precisely set the measurement delay (with 10 ns resolution) to align the pulse modulation and the data acquisition period. – In pulse mode, it is important to use receiver leveling to maintain power-level accuracy for power-dependent measurements, such as output power, compression, and intermodulation distortion.

(Options 028, 029) Noise igure measurement challenges with traditional, Y-factor approach – Multiple instruments and multiple connections required to fully characterize DUT –Measurement accuracy degrades in-ixture, on-wafer, and automated-test environments, where noise source cannot be connected directly to DUT – Measurements are slow, often leading to fewer measured data points and misleading results due to under-sampling PNA-X noise igure solution provides: –Ampliier and frequency converter measurements with the highest accuracy in the industry, using advanced error-correction methods –Fast measurements: typically 4 to 10 times faster than Keysight’s NFA Seri es noise igure analyzers – Ultra-fast noise-parameter measurements when used with Maury Microwave automated tuners, giving 200 to 300 times speed improvements On-wafer automated-test environment Noise source AUT Wafer probes For Y-factor measurements, any electrical network connected betwe en the noise source and the DUT, such as cables, switch matrices, and wafer probes, causes signiicant accuracy degradation. For this 401 point measurement of an unmatched transistor, the PNA-X exhibits much less ripple compared to the Y-factor method. The NFA default of 11 trace points would give under-sampled and therefore misleading results of the ampliier’s performance.

Noise-parameter measurements in minutes rather than days Noise igure measurement methods Y-factor: The most prevalent method for measuring noise igure is the Y-factor tech - nique. It relies on a noise source connected to the input of the device under test (DUT) . When the noise source is turned off, it presents a room temperature (cold) source termination. When the noise source is turned on, it creates excess noise, equiv alent to a hot source termination. Under these two conditions, noise power is measur ed at the output of the DUT, and the scalar gain and noise igure of the ampliier is calculated . The Y-factor method is used by Keysight’s NFA Series and by spectrum analyze rs with preampliiers and a noise igure personality option. Cold Source: An alternate method for measuring noise igure is the cold source or direct noise technique. With this method, only one noise power measurement i s made at the output of the DUT, with the input of the ampliier terminated with a room temperature source impedance. The cold source technique requires an independent measurem ent of the ampliier’s gain. This technique is well suited for vector network analy zers (VNAs) because VNAs can measure gain (S21) extremely accurately by utilizing vect or error correction. The other advantage of the cold source method is that both S-para meter and noise igure measurements can be made with a single connection to the DUT. SourceNoise parameters vs. frequency Frequency: 0.80 to 8.00 GHz Setting up and making noise-parameter measurements is simple and fast u sing a PNA-X and a Maury Microwave automated tuner. Maury’s latest software dramatically i mproves both the speed and ac- curacy of noise-parameter measurements, making them a practical opt ion for all RF engineers.

–Noise igure measurements are best done in a screen room to eliminate spurious interference from mobile phones, wireless LAN, handheld transceivers, etc. – Batteries are sometimes used instead of mains-based power supplies to eliminate conducted interference from sensitive LNA measurements – Overall measurement accuracy can be estimated by using Keysight’s Monte-Carlo-based noise igure uncertainty calculator Keysight’s PNA-X noise igure uncertainty calculator (www.keysight.com/ind/nfcalc) includes the effects of mismatch and noise-parameter-induced errors caused by imperfect system source match.

(Option 086) Gain compression measurement challenges –Characterizing ampliier or frequency converter compression over its op erating frequency range requires measurements at many frequency and power points, s o setting up the measurements, calibration, and data manipulation takes a lo t of time and effort – A variety of errors degrade measurement accuracy, such as mismatch between the test port and the power sensor and DUT during absolute power measurements, and using linear S-parameter error correction in nonlinear compression m easurements PNA-X gain compression application (GCA) provides: – Fast and convenient measurements with SMART Sweep –Highly accurate results using a guided calibration that provides power and m ismatch correction – Complete device characterization with two-dimensional (2D) sweeps, with the choice of sweeping power per frequency, or sweeping frequency per power – Flexibility with a variety of compression methods—compression from linear gain, maximum gain, X/Y compression, compression from back-off, or compressio n from saturation Pin Frequency Gain Compression point Pin Frequency Gain Compression point Iteration point A network analyzer is commonly used for gain compression measure - ments by performing power sweeps at multiple CW frequencies. The PNA-X’s GCA makes it easy to characterize compression over the DUT’s operating frequency range with extreme speed and accuracy, and a simple setup. Instead of a linear power sweep with many points, GCA’s SMART Sweep uses an adaptive algorithm to ind the desired compression point at each frequency with just a few power measurements, thus signiicantly reduc ing test times. Complete device response to 2D sweeps—gain versus frequency and power—can be extracted for device modeling. Using only power correction, incident power at compression point exhibits large ripple due to DUT mismatch Measurement ripple is reduced with GCA by using power and mismatch correction 16 | Keysight | PNA-X Series Microwave Network Analyzers - Brochure
Pin Freq. Gain Compression Pin Freq. Gain Compression Available compression methods – Use the safe mode in SMART Sweep to increment the input power irst with coarse and then with ine steps to prevent over driving the DUT – When the DUT’s hysteresis or thermal effects are in doubt, it is recommended to sweep frequency per power rather than power per frequency, or to add dwell time to lower the effects from previous measurements –Compression analysis capability extracts the DUT response over the power range at a speciied frequency point on any of the compression traces – Use the CompAI1 and CompAI2 internal voltmeter readings that are synchronized to the compression point to measure power-added eficiency (PAE) at compression for each frequency Measured background data in SMART Sweep with Safe Mode Off (above) and On (below)— more iterations are used as the gain becomes closer to the 1 dB compression point with Safe Mode On, which minimizes excess drive power. Compression from linear gain The linear gain is measured using the speciied linear (input) power level. The com - pression point is calculated as the linear gain minus the speciied compression level. Compression from max gain The highest gain value that is found at each frequency is used as the max gain. The com - pression point is calculated as the max gain minus the speciied compression level. Compression from back off The gains at two input powers that are dif - ferent with the speciied back off level are compared. The compression point is found as the highest input power with the gain differ - ence of the speciied compression level. X/Y compression The output powers at two input powers that are different with the speciied delta X are compared. The compression point is found as the highest input power with the output power difference of the speciied delta Y. Compression from saturation The compression point is found at the highest output power minus the value speciied as “From Max Pout”.

distortion (IMD) measurements with simple setup (Option 087) IMD measurement challenges – Two signal generators, a spectrum analyzer, and an external combiner are most commonly used, requiring manual setup of all instruments and accessories – Test times are slow when swept-frequency or swept-power IMD is measured – Instruments and test setups often cause signiicant measurement errors due to source-generated harmonics, cross-modulation, and phase noise, plus receiver compression and noise loor PNA-X with IMD application provides: – Fast swept IMD measurements of ampliiers and frequency con - verters, using internal combiner and two internal sources The PNA-X with IMD application replaces two signal generators and a spectrum analyzer in the system rack, simplifying the system coniguration and increasing test throughput. IMD application measures third order IMD and IP3 at 201 frequency (or power) points in a matter of seconds, compared to several minutes using signal generators and a spectrum analyzer. Frequency-offset mode is commonly available in VNA’s, but conventional IF ilter responses exhibit high side lobes. The IM Spectrum mode employs an optimized digital IF ilter and pro - vides true spectrum measurement capability in the PNA-X. Two internal sources with high output power, wide ALC range, -60 dBc harmon ics, and a high- isolation combiner, make the PNA-X an ideal instrument to drive the DUT for t wo-tone IMD measurements. Wide dynamic-range receivers with high compressio n points enable accurate measurements of low-power IMD products while the higher power main tone s are present.

– Calibrate at all measurement frequencies or at center frequencies only, trading off productivity and accuracy – Let the PNA-X control external signal generators to greatly simplify swept IMD measurements of mixers and converters – Use the Marker to IM Spectrum feature to show the spectrum at a speciied point on the swept IMD trace – Use point averaging with IM Spectrum, especially when using a wide resolution bandwidth, to reduce the noise deviation of the noise loor with minimum speed impact Calibrating all frequencies is recommended for wide tone spacing. Although the calibration takes longer with “all frequencies” , measurement speed is not affected. The IM Spectrum in the lower window shows the spectrum correspond- ing to the Swept IMD marker at the center of the trace in the upper window. Point averaging is applied to the IM Spectrum to reduce the noise deviation. IMD and IP3 versus LO power yields maximum IP3 with lowest possible LO drive power.

(Options 082, 083, 084) Mixer and converter measurement challenges – Traditional approach with spectrum analyzer and external signal sources is cumbersome, slow, and does not pro- vide phase or group delay information – Conventional VNAs require an external signal source, which degrades sweep speed – Conventional VNAs provide phase or group delay data relative to a “golden” device – Attenuators are often used to minimize ripple due to input and output mismatch, at the expense of dynamic range and calibration stability Option 083’s Scalar Mixer/Converter plus Phase (SMC+Phase) makes mixer and converter mea- surements simple to set up since reference and calibration mixers are not required. Calibration is easy to perform using three broadband standards: a power meter as a magnitude standard, a comb generator as a phase standard, and an S-parame- ter calibration kit (mechanical or ECal module). The Vector Mixer/Converter technique provides measurements of match, conversion loss/gain, delay, phase difference between multiple paths or devices, and phase shifts within a device.

With two internal signal sources, the PNA-X provides fast measurement s of both ixed and swept IF responses. Time-domain gating can remove ripple by removing unwanted, time-del ayed responses due to spurious signals. DUT Both SMC and VMC can be used to measure converters with embedded LOs, without need for access to internal time bases. Swept LO Fixed IF Fixed LO Swept IF Tips from the experts – Narrowing the IF bandwidth helps eliminate spikes on the measurement trace that result from LO feed through and other spurious signals from the DUT – To prevent source-unleveled errors when measuring devices with high-level spurious outputs (such as uniltered mixers), it is often helpful to increase the amount of source attenua- tion to provide better isolation between the DUT and the PNA-X – When making VMC measurements on multistage converters, it is best to create a single “meta-LO” signal that can be used to drive the reference and calibration mixers –When measuring uniltered mixers, time-domain gating can be a useful tool to reduce ripple by removing undesired, time-delayed responses due to spurious signals SMC’s match correction greatly reduces mismatch errors in conversion loss/gain measurements, eliminating the need for attenuators at the ends of the test cables. VMC’s match correction greatly reduces mismatch errors in group delay measurements, eliminating the need for attenuators at the ends of the test cables. 21 | Keysight | PNA-X Series Microwave Network Analyzers - Brochure
component characterization (Option 090) Spectrum analysis challenges for component testing – Measuring spurious performance is time consuming, especially when searching for low-level spurs over a broad frequency range –Long measurement times may force insuficient test coverage – Characterizing spurs over operating range of the DUT is tedious to accomplish or requires external control software PNA-X spectrum analyzer (SA) option provides: – Fast spurious searches over broad frequency ranges – A multi-channel SA with internal swept-signal generators for eficient spurious analysis of mixers and converters –In-ixture spectrum measurements using VNA calibration and de-embedding techniques – Fast band- and noise-power measurements – SA capability to the PNA-X’s single-connection, multiple- measurement suite Spectrum analyzer option adds fast spur search capability to the PNA-X, r eplacing a standalone spectrum analyzer and switch matrix in component-chara cterization test systems.

Measured spurs can include LO, RF, and IF feedthrough, harmonics, intermodulation products, and other higher-order mixing products. Conversion loss and match versus frequency is easily seen in a companion SMC channel (bottom).

(Option 090) Spectrum analysis challenges for component testing – Measuring spurious performance is time consuming, especially when searching for low-level spurs over a broad frequency range –Long measurement times may force insuficient test coverage – Characterizing spurs over operating range of the DUT is tedious to accomplish or requires external control software PNA-X spectrum analyzer (SA) option provides: –Fast spurious searches over broad frequency ranges –A multi-channel SA with internal swept-signal generators for eficient s purious analysis of mixers and converters –In-ixture spectrum measurements using VNA calibration and de-embedding techniques –Fast band- and noise-power measurements –SA capability to the PNA-X’s single-connection, multiple-measureme nt suite Spectrum analyzer option adds fast spur search capa- bility to the PNA-X, replacing a standalone spectrum analyzer and switch matrix in component-characterization test systems. 24 | Keysight | PNA-X Series Microwave Network Analyzers - Brochure
(Option 088) Ampliier load-pull measurement challenges –Ampliier gain, output power, and power eficiency are commonly measured unde r different output-load conditions to determine the optimum large-si gnal match – Traditional approach uses mechanical tuners which can handle high power, but are slow and cannot supply highly relective loads PNA-X with source-phase control provides –Control of second source to electronically tune relection coeficient at o utput of ampliier –Fast tuning speed and full relection – Match correction for accurate amplitude and phase control –Measurements of ampliier output power, match, gain, and PAE under different load conditions Example of load circles generated by keeping the magnitude of ΓL constant while sweeping phase Generate arbitrary output- load impedances by control - ling the magnitude and phase of the signal coming out of port 3 while the DUT is driven from port 1 Tips from the experts – Measurement setups can use receiver (R3, C...) or wave (a3, b3…) terminology – Use the equation editor to calculate the power delivered to the load (forward power - reverse power) as sqrt(pow(mag(b3_3),2) - pow(mag(a3_3),2)) – Use mechanical tuners and external software for hybrid load-pull systems that can handle high output power and achieve full relection – When using external signal sources, connect instru- ments to a common 10 MHz frequency reference 25 | Keysight | PNA-X Series Microwave Network Analyzers - Brochure
modulators, and differential mixers (Option 089) I/Q and differential converter measurement challenges – Requires signals with 90° or 180° phase difference –Traditional approach uses hybrid couplers and/or baluns which are: – Inherently band-limited, requiring multiple components for broadband measurements –Limited to ixed phase offsets, preventing phase sweeps to determine opti mum alignment – Lossy and inaccurate (+/- 3° to 12° typically) –Dificult to use with on-wafer setups PNA-X differential and I/Q devices application – Provides accurate phase control of internal and external sources, eliminating the need for hybrid couplers and baluns –Tunes receivers to all user-speciied output frequencies needed to fully ch aracterize the DUT – Sweeps frequency to measure operating bandwidth or sweeps phase and power at a ixed frequency to measure quadrature or differential imbalance – Includes match-corrected power measurements for highest accuracy The I/Q inputs of this modulator can be directly driven with the internal sources of the PNA-X, eliminating the need for a 90° hybrid coupler Tips from the experts – Two additional external sources can be used to create differential I/Q drive signals. The external sources must be routed through the PNA-X test set to measurement receivers in order to achieve the desired phase offsets. – For I/Q modulators, DC power supplies or source-measurement units (SMUs) can be routed through the bias tees to the I/Q inputs of the DUT. Voltage sweeps can then be performed to help ind the optimum I/Q- voltage offsets for the greatest amount of LO suppression. –Measure harmonics and total-harmonic distortion (THD) of different ial ampliiers by establishing a true-differential drive and tuning the PNA-X receivers to all desired harmonics – Measure compression of differential mixers using power sweeps 26 | Keysight | PNA-X Series Microwave Network Analyzers - Brochure
(Option 460) Differential ampliier measurement challenges – Conventional two-port VNAs with baluns do not provide common-mode, differential to common-mode, and common to differential-mode responses – Baluns are inherently band-limited devices, which forces multiple test setups for broad frequency coverage – Phase errors of baluns provide inac- curate differential responses – Modern four-port VNAs provide mixed-mode S-parameter measure- ments with single-ended stimulus, but differential ampliiers may respond differently when in compression during real operating environments PNA-X integrated true-mode stimulus application (iTMSA) provides: – Mixed-mode S-parameters of differential ampliiers driven by true differential and common-mode signals – Mismatch correction at the DUT input to minimize phase errors between two sources – Input-only drive mode that prevents damage on ampliiers caused by stimulus on the output port –In-ixture arbitrary phase offset and phase-offset sweeps to optimize input matching network for maximum ampliier gain 2 1 4 3 Differential (180 out-of-phase) Common (in-phase) Using the PNA-X’s two internal sources, iTMSA drives the differential ampliier under real world conditions, providing accurate mixed-mode S- parameters in all operating environments. Mixed-mode S-parameters. Without mismatch correction, the delivered signals to the DUT will not be truly differential due to relection from the DUT input and the subsequent re-relection from the sources. The relected signals overlay the original signals, causing phase and amplitude imbalance. This effect can be corrected with mismatch correction. iTMSA compensates for mismatch errors by measuring the raw matches of the VNA and DUT, and precisely adjusting the amplitude and phase of the two signals at the reference plane to achieve ideal true-mode signals. Phase error Amplitude error DUT mismatch Source mismatch Phase after mismatch correction Phase without mismatch correction Frequency (Hz) Phase Error (Deg) 27 | Keysight | PNA-X Series Microwave Network Analyzers - Brochure
Phase-offset sweeps change the phase- offset value as if it were added in the ixture, enabling input-matching circuit validation. Power or Gain Phase Offset (degrees from perfect differential) +10 -10 Actual Sdd21: Peaked at -5 degree phase offset Ideal Sdd21: peaked at 0 degree phase offset Differential input power -5 0 Various stimulus and sweep settings are available in the Balanced DUT Top ology dialog, allowing you to select the right coniguration for all of your balan ced devices. Tips from the experts – Input-only true-mode drive assumes a perfect match between the DUT output and the VNA’s test ports, which is a good assumption when the DUT’s reverse isolation is high. When the reverse isolation is low, adding attenuator s on the output port improves the system match and reduces mismatch errors. – When comparing the test results between single-ended and true-mode drive conditions with the same effective delivered differential power, th e individual port powers with true-differential drive must be set 6 dB lower than the port powers used with single-ended drive. Single-ended drive 0 dBm port power = -3 dBm differential power + -3 dBm common-mode power True differential drive -3 dBm port power = –6 dBm port 1 single-ended power + –6 dBm port 3 single- ended power In-ixture phase-offset sweeps reveal the optimal phase offset to achi eve the highest ampliier gain, which is essential to the design of the input matching circuit. 28 | Keysight | PNA-X Series Microwave Network Analyzers - Brochure
Powerful, fast and accurate automatic ixture removal (AFR) (Option 007) Powerful AFR features can handle a variety of measurement needs – Single ended and differential devices –Left and right side of ixture can be asymmetrical –Thru lengths can be speciied or determined from open or short measurements – Band-pass time-domain mode for band-limited devices – Extrapolation to match DUT frequency range –Power correction compensates for ixture loss versus frequency –De-embed iles can be saved in a variety of formats for later use in PNA, ADS, and PLTS AFR is the fastest way to de-embed a ixture from the measurement Measurement Challenge: Many of today’s devices do not have coaxial connectors and are put in ixtures in order to mea - sure them in a coaxial environ- ment. Accurately removing the effects of the ixture is required to get a good measurement of the device under test (DUT). A ive-step wizard guides you through the process to characterize your ixture and remove it from your measurement.

Today with AFR First calibrate in coax with the reference planes at the inputs to your ixture. Then measure one or more standards designed as a replica of the ixture’s 2-port thru, or ixture half terminated with an open or short. Or, even faster: just measure the actual ixture itself before the DUT is instal led for the open standard. AFR automatically characterizes and removes yo ur ix- ture from the measurement. 29 | Keysight | PNA-X Series Microwave Network Analyzers - Brochure
AFR accuracy is comparable to on-board TRL calibration, but much easier to accomplish. Measurement example In the plots below, the green trace is a measurement of a Beatty Standard DUT before AFR ixture removal. The red trace is the DUT with AFR open-standard ixture removal. The blue trace is the DUT with AFR thru-standard ixture removal. The effects of ixture mismatch and length are removed from the DUT measurements.

(Options 510, 514, 518, and 520) High-power design challenges – Active devices are commonly driven into nonlinear regions, often by design to increase power eficiency, information capacity, and output power – Under large-signal drive conditions, active devices distort time-domain waveforms, generating harmonics, intermodulation distortion, and spectral reg rowth – Current circuit simulation tools that rely on S-parameters and limited nonlinear behavioral models are no longer suficient to fully analyze and predict non linear behavior of devices and systems – Fewer design iterations are required to meet current time-to-market demands S-parameters in a nonlinear world In the past, when designing systems with high-power ampliiers (HPAs), des igners measured ampliier S-parameters using a vector network analyzer, loade d the results into an RF simulator, added other measured or modeled circuit elements, and t hen ran a simulation to predict system performance such as gain and power-eficie ncy under vari- ous loads. Since S-parameters assume that all elements in the system are linear, this a pproach does not work well when attempting to simulate performance when the ampliier i s in compression or saturation, as real-world HPAs often are. The errors are par ticularly ap- parent when simulating the combined performance of two cascaded devices t hat exhibit nonlinear behavior. While engineers may live with this inaccuracy, it in variably results in extensive and costly empirical-based iterations of the design, addin g substantial time and cost to the design and veriication process. 33 | Keysight | PNA-X Series Microwave Network Analyzers - Brochure
