Key Features & Specifications

A newer version of this product, the M9703B is recommended for new design.


  • Multi-channel applications requiring phase coherency, wideband frequency analysis, high dynamic range
  • Radar and satellite: antenna array calibration and test, electronic warfare (EW) radar emulation, passive radar receiver, or multi-band SATCOM monitoring
  • RF Communications: Multichannel Baseband-IQ (BBIQ) and wideband MIMO for emerging standards research (e.g. 5G)
  • Advanced research large scale experiments in hydrodynamics, plasma fusion (Tokamak/Stellarator), particle physics, or microwave astronomy

See Measurement Solution Examples: Active Antenna Test, Multi-Emitter Environment Test Signals


  • 8 channels of DC to 2 GHz input frequency range, 12-bit resolution
  • Up to 3.2 GS/s sampling rate (when interleaved)
  • Multi-module processing synchronization for >100 phase coherent channels
  • On-board FPGAs for custom processing or OTS wideband real-time DDC


Based on the AXIe standard  the M9703A is an 8-channel, 12-bit wideband digital receiver/digitizer, able to capture signals from DC up to 2 GHz at 1.6GS/s. A channel interleaving capability allows waveform acquisition at up to 3.2 GS/s with exceptional measurement accuracy.

The M9703A also provides real-time data processing with four Virtex 6 FPGAs and very long acquisition capability which can be accessed for custom processing implementation with the W1462BP SystemVue FPGA Architect. The SystemVue ESL design software provides an integrated design-to-test flow, with rich communication and A/D processing libraries as well as an automatic push button programming approach, allowing to accelerate customer’s design.

The M9703A FPGAs optionally feature real-time digital downconversion (DDC), allowing tuning and zooming on the signals to be analyzed. The DDCs improve the dynamic range, reduces the noise floor, and extends the capture time for an accelerated measurement speed. This feature also enables an accelerated connection to the software measurement layer, such as the 89600 Vector Signal Analysis, for faster signal analysis.

The multi-module processing synchronization allows building a system of >100 phase-coherent channels with the M9514A 14-slot AXIe chassis.
