3. Frequency Readout and Marker Frequency
Count Accuracy: Agilent E4401B, E4402B,
E4403B, and E4411B
The frequency readout accuracy of the analyzer is tested with an input
signal of known frequency. By using the same frequency standard for
the analyzer and the synthesized sweeper, the frequency reference error
is eliminated.
There are no related adjustment procedures for this performance test.
