Signal Level Problem with
Input Frequencies > 3.6 GHz
Measure the 4.8 GHz RF calibrator signal level by pressing

,
4.8 GHz
. Now press
Freq
and input
4.8 GHz
. Press
SPAN

and
Peak Search
. If the analyzer is functioning correctly in high band, the
4.8 GHz calibrator level should be
−
28 dBm
±
2 dB. See the figure below.
Is the signal level correct?
If yes:
The analyzer high band path is functioning properly at least at 4.8 GHz.
If no:
Press

,
Y-Scale
,
Preselector Center
to manually center the
preselector. Refer to
Chapter 4, “RF Section Troubleshooting
in this manual.
It is possible that other input frequencies > 3.6 GHz could have an amplitude problem even
though the 4.8 GHz calibrator is within tolerance. Using the internal RF calibrator provides a
quick check of the high band path.
