5G Channel Sounding, Reference Solution

The Keysight Satellite Signal Monitoring, Reference Solution is a fast, effective solution for monitoring large blocks of spectrum combined with precise digital modulation analysis to validate satellite signal integrity up to 50 GHz. Built upon a modular instrument format (PXIe), its attributes include: excellent instrument density, expandable multi-channel support, and high data bus speeds, ideal for multi-band monitoring. To provide flexibility, a choice of vector signal analyzers (M9391A and M9393A) is available to tailor the system frequency ranges as needed.


  • Build a cost-effective solution with a single PXIe VSA and sequential scanning configuration for monitoring several, non-overlapping bands or utilize up to four PXIe VSAs with a single 89600 VSA software license for parallel scanning applications
  • Scan multiple frequency bands and perform spectrum analysis measurements such as carrier power, center frequency and occupied bandwidth
  • Demodulate multiple signal formats including APSK, ASK, FSK, MSK, BPSK, CPM, QPSK, OQPSK, DQPSK, 8PSK, D8PSK, QAM, StarQAM, VSB, Custom APSK, Shaped Offset QPSK and more
  • Extend the transmission distance to more than 1500 meters (26 GHz)/1400 meters (50 GHz) of satellite signal from the antenna to the monitoring site using the optical extenders (M9403A PXIe Optical Transmitter, M9404A PXIe Optical Receiver, and M9405A PXIe RF Amplifier)


  • Spectrum Analysis Frequency Range: 1 MHz to 6 GHz (M9391A) and 9 kHz to 27 GHz; frequency extension to 50 GHz, with minimum frequency of 3.6 GHz (M9393A)
  • Frequency Span: Selectable, 800 Hz to full hardware frequency range
  • Modulation Analysis BW: Up to 160 MHz (M9391A) / Up to 800 MHz using an external digitizer (M9393A)
  • Spectrum Analysis Scan Rate: Single Scan (nominal) > 280 GHz/s (M9393A w/ Options UNZ & B16 and M9037A Embedded Controller)

Measurement applications and software

  • This Reference Solution includes Keysight’s 89600 VSA software for the spectrum analysis and digital demodulation tools required for this application.
  • To facilitate integration in your test environment, the example measurement setup files, test code logging, and 89600 VSA software automation layer examples can be customized to meet the needs of a particular satellite signal monitoring solution.
