Drive down the size of test When you need to measure basic S-parameters, the right mix of speed, performance and footprint gives you an edge. Sharpen your edge with the Keysight PXI vector network analyzer (VNA), ideal for: Wireless manufacturing test Handset component test Aerospace/defense depot maintenance level testing Aerospace/defense manufacturing test Get more VNA in less space The Keysight PXI VNA is a full two-port VNA that fits in just one slot. The PXI VNA also performs fast, accurate measurements and reduces your cost-of-test by letting you simultaneously characterize many devices -- two-port or multiport -- using a single PXI chassis. It offers the best PXI VNA performance on key specifications such as dynamic range, measurement speed, and trace noise. Each module is a completely independent two-port network analyzer and up to 16 modules can be added to a chassis for multi-site and multiport applications. All ports are fully synchronous so multiple ports can be measured simultaneously with multiport error correction applied. For more information, see page 28. Achieve confidence and continuity in measurements The M937xA extends Keysight’s expertise in metrology to the modular form factor. It provides the same quality results you have come to expect in our vector network analyzers. Here are a few examples of ways that we continue to provide measurement quality and continuity. Dynamic range: > 114 dB at 9 GHz, > 110 dB at 20 GHz Trace noise: < 0.003 dB Sweep speed: 18 to 33 msec across 401 points Maximum leveled power: up to +7 dBm Stability: 0.005 dB/°C up to 4 GHz <0.02 dB/°C up to 26.5 GHz Electronic calibration (ECal): enables fast, easy and accurate calibrations Maintain hardware compliance The M937xA is PXI compliant and designed to benefit from fast data interfaces. The PXI VNA can be integrated with other test and automation modules in either a PXIe or Hybrid slot. The PXI format offers high performance in a small, rugged package. It is an ideal deployment platform for many automated test systems. Pay for only the frequency range you need with the widest choice of frequency ranges from 300 kHz up to 26.5 GHz.
Easy integration into test environments Software platform Keysight soft front panels provide easy to use instrument communications. The graphical user interface guides developers through module setup using a similar look and feel as the popular PNA. Users can quickly configure the instrument parameters and perform calibrations. IO Libraries Keysight IO Libraries Suite offers fast and easy connection to both traditional and modular instruments. The Keysight IO Libraries Suite helps you by displaying all of the modules in your system, whether they are PXI, PXIe, or AXIe. From here you can view information about the installed software or launch the modules’ soft front panel directly from Keysight Connection Expert (KCE). KCE offers an easy way to find the correct driver for your instrument. Drivers The M937xA PXI VNA is supplied with a comprehensive portfolio of module drivers, documentation, examples, and software tools to help you quickly develop test systems with your software platform of choice. The module comes with IVI-COM, IVI-C, LabVIEW and MATLAB software drivers that work in the most popular T&M development environments including, LabVIEW and LabWindows/CVI from National Instruments, MATLAB from The MathWorks, Microsoft C/ C++, C#, and VB.NET. Easy software integration To help you get started and complete complex tasks quickly, the module software support provides context sensitive help, complete documentation and code examples that allow quick module set up. These code examples can be easily modified, so that the PXI VNA can be quickly integrated into a test system. Included are application code examples for LabVIEW, LabWindows/CVI, Visual Studio C, C++, and C#, Visual Basic, and MATLAB. The graphical user interface guides test engineers using a similar look and feel as Keysight’s popular PNA family of network analyzers The PXI VNA’s multiple programmatic interfaces allow for easy integration into test environments and reduced development time.

Specification (spec.) Warranted performance. Specifications include guardbands to account for the expected statistical performance distribution, measurement uncertainties, and changes in performance due to environmental conditions. All specifications and characteristics apply over a 25°C ±5°C range ambient and module temperature between 33°C to 46°C (unless otherwise stated). The following conditions must be met: Instrument has been turned on for 60 minutes with PXI VNA application running. Instrument is within its calibration cycle. Instrument remains at a stable surrounding environment temperature (between -10°C to 55°C) for 60 minutes prior to turn-on. Characteristic (char.) A performance parameter that the product is expected to meet before it leave s the factory, but that is not verified in the field and is not covered by the product warranty. A characteristic includes the same guardbands as a specification. Typical (typ.) Expected performance of an average unit at a stable temperature between 25°C ±5°C for 60 minutes prior to turn-on and during operation; does not include guardbands. It is not covered by the product warranty. The instrument must be within its calibration cycle. Nominal (nom.) A general, descriptive term or design parameter. It is not tested, and not covered by the product warranty. Calibration The process of measuring known standards to characterize an instrument's systematic (repeatable) errors. Corrected (residual) Indicates performance after error correction (calibration). It is determined by the quality of calibration standards and how well "known" they are, plus system repeatability, stability, and noise. Uncorrected (raw) Indicates instrument performance without error correction. The uncorrected performance affects the stability of a calibration Temperatures referred to in this document are defined as follows: Full temperature range = individual module temperature of 10°C to 70°C, as reported by the module, and environment temperature of 0°C to 55°C. Controlled temperature range = individual module temperature of 33°C to 46°C, as reported by the module, and environment temperature of 20°C to 30°C. Frequency break points For all tables in this data sheet, the specified performance at the exact frequency of a break is the degraded value of the two specifications at that frequency, unless otherwise indicated.

Multi-site operation is the ability to configure multiple independent PXI VNAs to operate independently in a single PXIe chassis. Up to ten independent PXI VNA instances have been demonstrated, allowing parallel testing of devices. Each instance of an independent PXI VNA can have different number o f ports, and can be triggered synchronously, or asynchronously. More than four independent PXI VNAs operating on a single controller may experience some degradation in performance due to processing limitations.
