Expanded PXI & AXIe instrument range by Keysight

July 21, 2016 // By Graham Prophet
Keysight Technologies has added instrumentation in the PXIe format for RF power amplifier and front-end-module tests, boosting speed and accuracy; and a new PXIe Gen 3 chassis, IO components and external PC option increase system bandwidth for data streaming, multi-channel and multi-chassis systems.

Added PXI and AXIe instruments and reference solutions span 5G, PA/FEM and digital interconnect test, to increase test speed, improve accuracy and reduce the overall footprint, and aare part of the company’s programme of RF, microwave and digital measurement expertise in the PXI and AXIe instrument form factors.


The M9019A PXIe 18-slot Gen 3 chassis, controller, I/O components and external PC option claim the highest system bandwidth on the market. This series of PXIe system components offer at least two times more system bandwidth than a typical Gen 2 chassis, and the external PC option removes the limitations on PC selection imposed by closed PXIe systems. With Keysight’s open Gen 3 platform, customers can select an external PC or controller that best meets their need. For example, a 5G or electronic warfare application requiring a PC optimized for the capture and playback of large data streams; or a MIMO application requiring a large, multi-channel and multi-chassis PXIe test systems.


The 4-slot M9421A PXIe vector transceiver (VXT) and the M9111A PXIe high-speed source/measure unit (SMU) improve test throughput, reduce the overall footprint, and are built for production test and design validation of next-generation PA/FEMs. Covering frequencies from 60 MHz to 6 GHz, with modulation and analysis bandwidth up to 160 MHz, the VXT supports FPGA-accelerated measurements and includes software that supports analogue demodulation, noise figure and a broad range of cellular and wireless connectivity formats. The SMU changes voltage, stabilizes and accurately measures micro-Amps, all in less than 1 msec. This is a 20 times speed improvement over previous-generation, stand-alone Keysight SMUs, and is a fraction of the size.


The Digital Interconnect Test reference solution is presented as the fastest cable tester available and features the PXI VNA with full cross-bar s-parameter calibration of 32-ports up to 26.5 GHz. The PLTS software offers complete domain analysis with a convenient production test interface.
