Extended Frequency Range Operation - Keysight Technologies M9393A Startup Manual

Signal Analyzer.

Extended Frequency Range Operation

To connect to your M9393A with frequency range extension (3.6 GHz to 50 GHz)
option, the 89600 VSA software supports two hardware configurations (with and
without the M9169E Step Attenuator). For a wider frequency range extension but a
relatively lower upper frequency bound (9 kHz to 40 GHz), use the M9155CH40
switch module. The detailed information for configuring these arrangements is
available at
following steps to achieve higher frequency ranges:
1. Set the Input field to Keysight M9169E Attenuator in the New Hardware
Configuration dialog. See Step 2 in the above procedure.

As a best practice, after setting up an M9393A measurement, perform a
Disconnect/Restart (
unlocked Frequency Reference or Digitizer 100 MHz clock missing
condition, the M9214A Digitizer status LED will turn to Red and the INT REF
indicator at the bottom of the display will indicate "UNLOCKED" or "Waiting
for Frequency Reference Lock". At this point, troubleshoot the instrument
cabling. Perform a Disconnect/Restart again to verify that the frequency
reference is present.
Whether the problem is a broken 100 MHz clock path or an invalid External
Reference (either not present or mismatched frequency), the reference
status and measurement status messages are the same - "UNLOCKED"
reference and "Waiting for frequency reference" measurement status.
However, if the external reference signal (not the 100 MHz clock) is invalid,
as soon as the signal becomes valid, measurement will resume; whereas in
the 100 MHz clock signal case, you must
then reconnect ( Restart
