The output frequency of the 3 GHz tracking generator may not exactly

match the input frequency of the spectrum analyzer. This is probably
not a problem when using wide resolution bandwidths. However,
narrowing the RBW may cause a drop in the displayed signal amplitude
as the frequency offset puts the signal out of the center of the RBW
filter. For narrower RBWs you may need to do a tracking peak to adjust
the tracking generator frequency. See the

power for your tracking generator.

output may be accidentally damaged. This is because the actual source
amplitude will be greater than the amplitude indicated on the analyzer,
when the power sweep function is being used.
The source amplitude value is used as the starting amplitude for a
power sweep. The ending amplitude for a power sweep is higher then
the source amplitude value and it may actually be set to values beyond
specified output levels. Therefore, exercise caution when connecting a
power-level sensitive device to the tracking generator output.
