Keysight adds 10 PXI AWG and digitizer modules

-February 23, 2017

Keysight Technologies takes another aim at PXI rival National Instruments with the introduction of ten PXI modules for generating and capturing waveforms. The set consists of two FPGA-based digitizers, four FPGA-based arbitrary waveform generators (AWGs), one AWG for generating IQ signals, and three oscilloscopes. The table below lists the models, basic specifications, and U.S. list prices. Links take you directly Keysight's data sheets.

Model Description Price
M3100A FPGA digitizer, 100 MSamples/s, 4 or 8-channel $6200
M3102A FPGA digitizer, 500 Msamples/s, 2 or 4-channel $7800
M3201A FPGA arbitrary waveform generator, 500 MSamples/s $5700
M3202A FPGA arbitrary waveform generator, 1 GSamples/s $8300
M3300A FPGA AWG/digitizer, 500 MSamples/s. 2-ch $12,900
M3302A FPGA AWG/digitizer, 500 MSamples/s. 4-ch $14,500
M9336A IQ arbitrary waveform generator, 1 GHz bandwidth, 3-channel $22,000
M9241A Oscilloscope, 200 MHz $5500
M9242A Oscilloscope, 500 MHz $8500
M9243A Oscilloscope, 1 GHz $12,000

The FPGA-based instruments in the table come from Signadyne, acquired by Keysight in 2016. The addition of the FPGA gives digitizers the ability to perform data processing on board, relieving the system controller from that resource-intensive task. NI has had that ability for some time. Where Keysight differs is in having FPGAs for AWGs, a market NI has yet to enter. Adding an FPGA to a waveform generator lets you program waveforms with complex modulation for emulating wireless signals such as multiple input multiple output (MIMO). A graphical design environment lets you program the FPGA.

The AWGs also have function-generator capabilities for sine, square, triangular, and DC signals. They're programmable in C, C++, Visual Studio, LabVIEW, MATLAB, Python, and other languages. FPGA programming is optional through a graphical programming environment that lets you add algorithms generated in Matlab/SimuLink, and Xilinx CORE Generator IP cores, and VDHL.

Keysight's PXI oscilloscopes have two analog inputs and can send up to 1 million waveforms/s update rate to its soft-front panel or to your application through a driver. They also include a 3-digit DMM, a 20-MHz waveform generator, serial-bus triggering (I²C, UART, CAN, LIN, CXP) and mask testing. You can also perform frequency analysis through an FFT. Zone triggering, found on Keysight's bench oscilloscopes, lets you trigger an acquisition when a signal enters or exits a user=defined area.
