PXI General Purpose Switch Module

데이터 시트


Product description

The PXI general purpose switch modules offer a variety of switch designs enabling you to select the best configuration for your test application. Choose a switch optimized for high speed or high power, available in either Form A (single-pole, single-throw) or Form C (single-pole, double-throw) configurations.

The individual modules range from 20 channels up to 100 channels. The general purpose switches manage system controls by cycling power to your device under test (DUT), setting indicators and status lights, or actuating external power relays and solenoids.

Installation and configuration is fast and easy with standard cable connections or an optional connector block, soft front panels, and Keysight Connection Expert. In addition, software drivers support the most common programming environments such as Visual Studio, C, C++, Visual Basic, MATLAB, and LabVIEW.

Easy Setup, Test and Maintenance

Hardware platform


The general purpose switch modules are PXI compliant with a J1 connector and can be used in PXI chassis with cPCI (J1), PXI-1 (J1 only), or PXIe hybrid slot connectors.

The PXI format offers high performance in a small, rugged package. It is an ideal deployment platform for many automated test systems. In addition, a wide selection of complementary PXI products are currently available, such as multimeters, waveform generators, local oscillators, and digitizers.

Software platform

IO Libraries

Keysight IO Libraries Suite offers fast and easy instrument connections and now extends to modular instruments. IO Libraries Suite 16 (or greater) adds support for PXI, helping you display all of the modules in your system, whether they are PXI, PXIe, or AXIe, as well as view information about installed software. In addition, the new version allows you to more easily find the right driver and start module soft front panels directly with Keysight Connection Expert.


Keysight Technologies, Inc. provides instrument drivers that work with your choice of software, saving time and preserving software and hardware investments.

Keysight modular instruments come with IVI-COM, IVI-C, and LabVIEW software drivers that work in the most popular test and measurement development environments including LabVIEW, MATLAB, LabWindows/CVI, Visual Studio C, C++, C#, VEE, and Visual Basic.

With a broad selection of drivers already included, any Keysight PXI general purpose switch can be swapped out, replaced, or upgraded with the latest version, requiring only minimal software adjustments.

Easy software integration

In addition, application code examples are included for LabVIEW, LabWindows/CVI, Visual Studio C, C++, C#, Visual Basic, and MATLAB, providing switch setup and basic functionality. These application code examples are easily modified to quickly integrate the switch module into your measurement system.

Software applications

Keysight soft front panels provide easy-to-use instrument communications. The PXI general purpose switch graphical user interface guides developers through module setup so users can quickly configure the switch states. Switch control is also possible through the wide selection of instrument program interfaces.
