Boot Up and Initialization Troubleshooting
Signal Level Verification
Signal Level Problem with
Input Frequencies > 3.6 GHz
Measure the 4.8 GHz RF calibrator signal level by pressing Input/Output, {RF
Calibrator}, 4.8 GHz. Now press Freq, 4.8 GHz, SPAN, 1 MHz, 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:
Refer to Chapter 4, “RF Section Troubleshooting (RF/Microwave
Analyzers)” 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.
