PXIe Multiport Vector Network Analyzer

High-Performance PXI Multiport Vector Network Analyzer (VNA)

Innovative solution

Today’s measurement requirements of components or modules used for wireless communication are getting more complicated based on growing technology and multi-carrier and multi-band coverage needs. The Keysight M9485A PXI multiport VNA is an ideal solution that provides flexible and scalable configuration, and solves your increasing challenges. Adapting independent source and receiver configuration, it offers the best measurement performance in multiport network analysis. Using the latest converged software platform that leverages the best attributes of the ENA and PNA families, it also offers comprehensive functions to test multiport components like front-end modules, filters, and switches. Build the production line with the M9485A and drive down the cost of test.

Best-in-class performance for multiport testing

The M9485A has best-in-class fast measurement speed and wide dynamic range, as well as Keysight VNA’s common high stability and low trace noise for multiport testing. It helps you achieve the lowest cost of test with fast throughput, high accuracy, better yields and less down time.

Fast speed

The M9485A’s measurement speed increases throughput and decreases cost of test, especially in high-volume manufacturing, with best-in-class measurement speed in multiport network analysis.

Wide dynamic range

Wide dynamic range not only helps increase throughput of high rejection device test, but also improves test accuracy and yield. M9485A has up to 142 dB2 dynamic range, best-in-class in PXI VNA, and comparable to the best bench-top VNAs.

Low trace noise and high stability

The M9485A inherits excellent low trace noise and high stability, common factors to all Keysight VNAs. Low trace noise of 0.001 dBrms3 enables fast and accurate measurements. High stability of 0.005 dB/°C4 increases calibration interval time and maintains accurate measurement performance, which decreases the operation down time for calibration.

Flexible Multiport Configuration with Full N-Port Correction

You can customize the M9485A to measure your DUTs most effectively. The M9485A supports from 4-port to 24-port configurations and users can easily increase or decrease the number of ports by adding, re-assigning, or removing modules in the system according to current and future test needs.

The M9485A is a true multiport VNA with up to 24 ports, independent receivers at each port. This configuration drastically decreases the total number of sweep times for multiport measurements compared to a switch matrix based solution. For example, a 16 port measurement takes 16 sweeps for the M9485A, but takes up to 240 sweeps for a 2-port VNA with a switch matrix. By using the M9485A, you can dramatically increases test throughput.

Multiport measurements

The M9485A uses the latest Keysight VNA software platform. It helps you set and measure multiple traces easily and intuitively. Up to 200 measurement channels and unlimited traces setups enable setting flexible multiport measurements. A guided calibration menu and copy channel feature enable full N-port calibrations and set stimulus conditions quickly.

Flexible setting of multi-site measurements

You can set a single stimulus source for multiple test ports at the same time. This feature enables simultaneous and flexible multiport and multi-site measurements. The multi DUT measurement tool helps setup multiport and multi-site measurement by the M9485A. You can drastically increase total test throughput and lower cost of test per device by this capability.

Flexible traces and windows layout

The layout of traces and windows can be flexibly allocated with intuitive drag-and -drop operations. It enables you to overly traces with different channel settings on the same windows.
