Multimeter heightens test perfor- mance in three phases of your pro - duction test: faster test system start- up, faster test throughput, and lower cost of ownership through longer system uptime, designed-in reliability, and fast and easy calibration. Faster system start-up The value of a fast system multimeter in production test is clear. But it is also important that the dmm programs easily to reduce the learning time for new system applications. The Keysight Multimeter Language (ML) offers a standard set of commands for the multimeter user that consists of easily understood, readable com- mands. Easier programming and clearer documentation reduce system development time. Faster measurements and setups Now you can have a system dmm with both fast and accurate measure- ments. The 3458A optimizes your measurements for the right combi- nation of accuracy, resolution, and speed. The 3458A Multimeter fits your needs from 4.5 digit DC volts measurements at 100,000/second, to 8.5 digit DC volts measurements at 6/second, or anywhere in between in 100 ns steps. Even the traditionally slower measure- ment functions, such as AC volts, are quicker with the 3458A. For example, you can measure true rms ACV at up to 50 readings/second with full accuracy for input frequencies greater than 10 kHz. Besides high reading rates, the 3458A’s design was tuned for the many function and level changes required in testing your device. The 3458A can change function and range, take a measurement, and output the result at 340/second. This is at least 5 times faster than other dmms. In addition, the 3458A transfers high speed measurement data over GPIB or into and out of its 75,000 reading memory at 100,000 readings/second. You can reduce your data transfer overhead by using the unique non- volatile program memory of the 3458A to store complete measurement sequences. These test sequences can be programmed and initiated from the front panel for stand-alone operation without a controller. Finally, the 3458A Multimeter makes fast and accurate measurements. Consider the 3458A’s 0.6 ppm 24 hour DC volts accuracy, 100 ppm AC volts accuracy and its standard functions of DCV, ACV, DCI, ACI, ohms, frequency and period. Greater measurement accuracy from your dmm means higher confidence and higher test yields. More functions mean greater versatility and lower-cost test systems. Longer system up-time The 3458A Multimeter performs a complete self-calibration of all func- tions, including AC, using high stabil- ity internal standards. This self- or auto-calibration eliminates measure- ment errors due to time drift and temperature changes in your rack or on your bench for superior accuracy. When it’s time for periodic calibration to external standards, simply con- nect a precision 10 VDC source and a precision 10 kΩ resistor. All ranges and functions, including AC, are auto- matically calibrated using precision internal ratio transfer measurements relative to the external standards. The 3458A’s reliability is a product of Keysight’s “10X” program of defect reduction. Through extensive envi- ronmental, abuse, and stress testing during the design stages of product development, has reduced the num- ber of defects and early failures in its instruments by a factor of ten over the past ten years. Our confidence in the 3458A’s reliability is reflected in the low cost of the option for additional years of return-to-repair. For High Test System Throughput – Faster system start-up Multimeter Language (ML) compat- ible – Faster measurements and setups 100,000 readings/sec in 4.5 digits 50,000 readings/sec in 5.5 digits 340 function or range changes/sec – Longer system up-time Multimeter Language (ML) compatible

In the calibration lab, you’ll find the 3458A’s 8.5 digits to have extraordi- nary linearity, low internal noise, and excellent short term stability. The linearity of the 3458A’s Multislope A to D converter has been characterized with state-of-the-art precision. Using Josephsen Junction Array intrinsic standards, linearity has been mea- sured within ± 0.05 ppm of 10 volts. The 3458A’s transfer accuracy for 10 volts DC is 0.1 ppm over 1 hour ± 0.5° C. Internal noise has been reduced to less than 0.01 ppm rms yielding 8.5 digits of usable resolution. So, the right choice for your calibration standard dmm is the 3458A. DCV stability The long term accuracy of the 3458A is a remarkable 8 ppm per year— more accurate than many system dmms are after only a day. Option 002 gives you a higher stability voltage reference specified to 4 ppm/year for the ultimate performance. Reduced-error resistance The 3458A doesn’t stop with accurate DCV. Similar measurement accuracy is achieved for resistance, ACV, and current. You can measure resistance from 10 µΩ to 1 GΩ with midrange accuracy of 2.2 ppm. Finally, the 3458A, like its dmm pre - decessors, offers offset-compensated ohms on the 10 Ω to 100 kΩ ranges to eliminate the errors introduced by small series voltage offsets. Usable for both two- and four-wire ohms, the 3458A supplies a current through the unknown resistance, measures the voltage drop, sets the current to zero, and measures the voltage drop again. The result is reduced error for resistance measurements. Precision ACV The 3458A introduces new heights of true rms AC volts performance with a choice of traditional analog or a new sampling technique for higher accu- racy. For calibration sources and peri- odic waveforms from 1 Hz to 10 MHz, the 3458A’s precision sampling tech- nique offers extraordinary accuracy. With 100 ppm absolute accuracy for

45 Hz to 1 kHz or 170 ppm absolute

accuracy to 20 kHz, the 3458A will enhance your measurement capabili- ties. Accuracy is maintained for up to 2 years with only a single 10 volt DC precision standard. No AC standards are necessary. For higher speed and less accuracy, the analog true rms AC technique has a midband absolute measurement accuracy of 300 ppm using the same simple calibration procedure. With a bandwidth of 10 Hz to 2 MHz and reading rates to 50/ second, is an excellent choice for high throughput computer-aided testing. Easy calibration The 3458A gives you low cost of ownership with a simple, two-source electronic calibration. With its superior linearity, the 3458A is fully calibrated, including AC, from a precision 10 VDC source and a precision 10 kΩ resistor. All ranges and functions are automat- ically calibrated using precise internal ratio transfer measurements relative to these external standards. In addi- tion, the 3458A’s internal voltage standard and resistance standard are calibrated. Now you can perform a self-verifying, self- or auto-calibration relative to the 3458A’s low drift inter - nal standards at any time with the ACAL command. So, if your dmm’s environment changes, auto-calibration optimizes your measurement accuracy. Calibration security Unlike other dmms, the 3458A goes to great lengths to assure calibration security. First, a password security code “locks” calibration values and the self-calibration function. Next, you can easily store and recall a secured message for noting items, such as calibration date and due date. Plus, the 3458A automatically increments a calibration counter each time you “unlock” the dmm — another safe- guard against calibration tampering. If you have a unique situation or desire ultimate security, use the inter- nal dmm hardwired switch to force removal of the instrument covers to perform calibration. For Calibration Lab Precision – 8.5 digits resolution – 0.1 ppm DCV linearity – 100 ppm ACV absolute accuracy – 4 ppm/year optional stability

For High Resolution Digitizing – 16 bits at 100,000 samples/sec – Effective rates to

100 Msamples/sec

– Signal bandwidth of

12 MHz

– 10 ns timing with < 100 ps jitter Easily acquire waveforms Simple, application-oriented commands in the Keysight Multimeter Language (ML) make the task of waveform digitizing as easy as measuring DCV. Simply specify the sweep rate and number of samples. Integration or track-and-hold paths The 3458A gives you the choice of two configurations for high speed measurements: a 150 kHz bandwidth integrating path with a variable aper- ture from 500 ns to 1 second or a

12 MHz bandwidth path with a fixed

2 ns aperture and 16-bit track-and-hold. Use the integration path for lower noise, but use the track-and-hold path to precisely capture the voltage at a single point on a waveform. Direct sampling function The 3458A has two sampling functions for digitizing wave-forms: direct sampling and sequential or sub-sampling. With direct sampling, the 3458A samples through the

12 MHz path followed by the 2 ns

track-and-hold providing 16 bits of resolution. The maximum sample rate is 50,000 samples/second or 20 µs between samples. Samples can be internally paced by a 0.01% accurate timebase with time increments in 100 ns steps. Data transfers directly to your computer at full speed or into the dmm’s internal reading memory. Waveform reconstruction consists of simply plotting the digitized voltage readings versus the sampling interval of the timebase. Sequential sampling function Sequential or sub-sampling uses the same measurement path as direct sampling; however sequential sampling requires a periodic input signal. The 3458A will synchronize to a trigger point on the waveform set by a level threshold or external trigger. Once synchronized, the dmm automatically acquires the waveform through digitizing successive periods with time increment steps as small as 10 ns, effectively digitizing at rates up to 100 Msamples/second. All you specify is the effective timebase and the number of samples desired, the 3458A automatically optimizes its sampling to acquire the waveform in the least amount of time. Then, for your ease of use, the 3458A automati - cally re-orders the data in internal memory to reconstruct the waveform.

3458A Technical Specifications EXAMPLE 5: Absolute Accuracy; 90 Day Assuming the same conditions as Example 4, but now add the traceability error to establish absolute accuracy. (4.1 ppm x 10 V) + (0.05 ppm x 10 V) = 42 µV Temperature Coefficient (specification is per °C): (0.15 ppm x 10 V + 0.01 ppm x 10 V) x 10 °C = 16 µV factory traceability error of 2 ppm: (2 ppm x 10 V) = 20 µV Total absolute error = 78 µV Additional errors When the 3458A is operated at power line cycles below 100, additional errors due to noise and gain become significant. Example 6 illustrates the error correction at 0.1 PLC. EXAMPLE 6: Operating temperature is 28°C; 0.1 PLC Assuming the same conditions as Example 2, but now add additional error. (4.1 ppm x 10 V) + (0.05 ppm x 10 V) = 42 µV Referring to the Additional Errors chart and RMS Noise Multiplier table, additional error at 0.1 PLC is: (2 ppm x 10 V) + (0.4 ppm x 1 x 3 x 10 V) = 32 µV Total relative error = 74 µV Section 1: DC Voltage 10 Section 7: Digitizing 21 Section 2: Resistance 11 Section 8: System Specifications 23 Section 3: DC Current 13 Section 9: Ratio 24 Section 4: AC Voltage 14 Section 10: Math Functions 24 Section 5: AC Current 19 Section 11: General Specifications 25 Section 6: Frequency/Period 20 Section 12: Ordering Information 26 Introduction The Keysight 3458A accuracy is specified as a part per million (ppm) of the reading plus a ppm of range for DCV, Ohms, and DCl. In ACV and ACl, the speci- fication is percent of reading plus percent of range. Range means the name of the scale, e.g. 1 V, 10 V, etc.; range does not mean the full scale reading, e.g. 1.2 V, 12 V, etc. These accuracies are valid for a specific time from the last calibration. Absolute versus Relative Accuracy AII 3458A accuracy specifications are relative to the calibration standards. Absolute accuracy of the 3458A is determined by adding these relative accuracies to the traceability of your calibration standard. For DCV, 2 ppm is the traceability error from the factory. That means that the absolute error relative to the U.S. National Institute of Standards and Technology (NIST) is 2 ppm in addition to the DCV accuracy specifications. When you recalibrate the 3458A, your actual traceability error will depend upon the errors from your calibration standards. These errors will likely be different from the error of 2 ppm. EXAMPLE 1: Relative Accuracy; 24 hour operating temperature is Tcal ±1 °C Assume that the ambient temperature for the measurement is within ± 1 °C of the temperature of calibration (Tcal). The 24 hour accuracy specification for a 10 V DC measurement on the 10 V range is 0.5 ppm + 0.05 ppm. That accuracy specification means: 0.5 ppm of Reading + 0.05 ppm of Range For relative accuracy, the error associated with the measurement is: ± 5.5 µV or 0.55 ppm of 10 V Errors from temperature changes The optimum technical specifications of the 3458A are based on auto-calibration (ACAL) of the instru- ment within the previous 24 hours and following ambient temperature changes of less than ±1 °C. The 3458A’s ACAL capability corrects for measure- ment errors resulting from the drift of critical components from time and temperature. The following examples illustrate the error correc- tion of auto-calibration by computing the relative measurement error of the 3458A for various temperature conditions. Constant conditions for each example are:

Tcal = 23 °C 90 day accuracy specifications EXAMPLE 2: Operating temperature is 28 °C; with ACAL This example shows basic accuracy of the 3458A using auto-calibration with an operating tempera- ture of 28 °C. Results are rounded to 2 digits. (4.1 ppm x 10 V) + (0.05 ppm x 10 V) = 42 µV Total relative error = 42 µV EXAMPLE 3: Operating temperature is 38 °C; without ACAL The operating temperature of the 3458A is 38 °C, 14 °C beyond the range of Tcal ±1 °C. Additional measurement errors result because of the added temperature coefficient without using ACAL. (4.1 ppm x 10 V) + (0.05 ppm x 10 V) = 42 µV Temperature Coefficient (specification is per °C): (0.5 ppm x 10 V + 0.01 ppm x 10 V) x 14 °C = 71 µV Total error = 113 µV EXAMPLE 4: Operating temperature is 38°C; with ACAL Assuming the same conditions as Example 3, but using ACAL significantly reduces the error due to temperature difference from calibration tempera- ture. Operating temperature is 10 °C beyond the standard range of Tcal ±5 °C. (4.1 ppm x 10 V) + (0.05 ppm x 10 V) = 42 µV Temperature Coefficient (specification is per °C): (0.15 ppm x 10 V + 0.01 ppm x 10 V) x 10 °C = 16 µV Total error = 58 µV

Section 3: DC Current Measurement Considerations Keysight recommends the use of PTFE cable or other high impedance, low dielectric absorption cable for low current measurements. Current measurements at rates < NPLC 1 are subject to potential noise pickup. Care must be taken to provide adequate shielding and guarding to maintain measurement accuracies.

Section 4: AC Voltage Synchronous Sub-sampled Mode (ACV Function, SETACV SYNC) General Information The Keysight 3458A supports three techniques for measuring true rms AC voltage, each offering unique capabilities. The desired measurement technique is selected through the SETACV command. The ACV functions will then apply the chosen method for subsequent measurements. The following section provides a brief description of the three operation modes along with a summary table helpful in choosing the technique best suited to your specific measurement need. SETACV SYNC Synchronously Sub-sampled Computed true rms technique. This technique provides excellent linearity and the most accurate measurement results. It does require that the input signal be repetitive (not random noise for example). The bandwidth in this mode is from 1 Hz to 10 MHz. SETACV ANA Analog Computing true rms conversion technique. This is the measurement technique at power-up or following an instrument reset. This mode works well with any signal within its 10 Hz to 2 MHz bandwidth and provides the fastest measurement speeds. SETACV RNDM Random Sampled Computed true rms technique. This technique again provides excellent linearity, however the overall accuracy is the lowest of the three modes. It does not require a repetitive input signal and is threfore well suited to wideband noise measurements. The bandwidth in this mode is from 20 Hz to 10 MHz.

Section 7: Digitizing Standard DC Volts Digitizing (DCV Function) General Information The Keysight 3458A supports three independent methods for signal digitizing. Each mehtod is discussed below to aid in selecting the appropriate setup best suited to your specific application. DCV Standard DCV function. This mode of digitizing allows signal acquisition at rates from 0.2 readings/sec at 28 bits resolution to 100 k read- ings/sec at 16 bits. Arbitrary sample apertures from 500 ns to 1 sec are selectable with 100 ns resolution. Input voltage ranges cover 100 mV to 1000 V full scale. Input bandwidth varies from 30 kHz to 150 kHz depending on the measurement range. DSDC Direct Sampling DC Coupled measurement technique. DSAC Direct Sampling AC Coupled measurement technique. In these modes the input is sampled through a track/hold with a fixed 2 ns aperture which yields a 16 bit resolution result. The sample rate is selectable from 6000 sec/sample to 20 µs/sample with 100 ns resolution. Input voltage ranges cover 10 mV peak to 1000 V peak full scale. The input bandwidth is limited to 12 MHz. SSDC Sub-Sampling (Effective time sampling) DC Coupled. SSAC Sub-Sampling (Effective time sampling) AC Coupled. These techniques implement synchronous sub-sampling of a repetitive input signal through a track/hold with a 2 ns sample aperture which yields a 16 bit resolution result. The effective sample rate is settable from 6000 sec/sample to 10 ns/sample with 10 ns resolution. Sampled data can be time ordered by the instrument and output to the GPIB. Input voltage ranges cover 10 mV peak to 1000 V peak full scale. The input bandwidth is limited to 12 MHz.
