Service and Diagnostics Menus
Service Key Descriptions
Corrections
The Corrections menu for the multi-touch display in UXA is labeled the Service
Diagnostics menu under the Spectrum Analyzer Mode, Measure Setup menu.
It allows the technician to activate and deactivate specific amplitude correction
sets. With this capability, the technician can determine if an anomaly is a result
of raw hardware performance or incorrect correction data. It also allows the
technician the ability to measure the raw hardware performance when all
corrections are set to Off.
RF Flatness Video Shift On/Off
The Flatness Video Shift turns off the corrections for gain vs. frequency. It
does not turn off the corrections for changes in the analog IF gain that
accompany flatness changes. This function turns both the gain and video
shift on or off, but does not affect the temperature corrections. When set to
off, it is possible to measure the raw flatness of the spectrum analyzer while
maintaining the temperature corrections.
When
Flatness Video Shift
is
Off
, the Advisory Event “Flatness Video Shift
OFF” will be displayed.
When
Flatness Video Shift
is
ON
, the Advisory Event “Flatness Video Shift
OFF” will be cleared.
The example spectrum below shows the effect of turning off RF Flatness
Video. The yellow trace shows RF Flatness Video shift on, and the Blue
trace shows RF Flatness Video shift off.
