System Settings
Utilities
IMPORTANT! The Frequency Extender feature uses the Remote Server
feature that requires the FieldFox to have CPU2 installed. Refer to the
A-Series Configuration Guide,
https://www.keysight.com/us/en/assets/7018-03329/configuration-guid
es/5990-9836.pdf.
The Frequency Extender (Freq Extnd) is only active (available) when one of
the following modes are enabled: SA/RTSA/IQA/OTA/PAA/VSA (via the
Remote Server feature – Requires CPU2).
When OML millimeterwave extenders are used, Cable and Antenna
corrections, if On, are included in eCorr, or Extended Corrections.

How to view and change the Frequency Extender (Freq Extnd) Settings

The following are the only supported modes for the frequency extender feature:
SA (Option 233, mixed analyzers, RTSA (Option 350), IQA (Option 351), OTA
(Option 370/377/378), PAA (Option 360) modes, and VSA (via the Remote
Server feature).
IMPORTANT!
When using a frequency extender with the FieldFox under certain
conditions, the A-Series FieldFox has low–band sub-harmonics that can
become visible and can affect some measurements. To minimize these
unwanted sub-harmonics:
– When using the mixer, the LO power should be reduced to –12 dBm and
– Reduce frequency span to make measurements until the "unleveled
power" message goes away (requires ≥A.12.40 firmware)
If you upgrade your FieldFox firmware to ≥A.12.40, but find you are unable
to adjust the LO power level to –12 dBm, refer to
