Description
The specification listed is for cumulative error. Only cumulative error is measured in this procedure.
A signal source of known amplitude is connected to the spectrum analyzer and the analyzer is adjusted for a reference. The signal source is stepped down in 1 dB steps and the displayed signal amplitude on the spectrum analyzer measured at each step. This measurement is performed in both the 3 kHz and 300 kHz bandwidths.
Operation Verification 5-13
