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” in this manual.

NOTE 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.
