Frequency Readout Accuracy

Frequency Readout Accuracy
Test Limits
Frequency Readout Accuracy is equivalent to the following equation:
±
See results table for actual values.
The frequency readout accuracy is measured in several spans and center
frequencies that allow both internal analyzer synthesizer modes and prefilter
bandwidths to be tested. Frequency reference error is eliminated by using the
same frequency standard for the analyzer and signal source.
