Frequency Readout Accuracy

Test Limits
Frequency Readout Accuracy is equivalent to the following equation:
± ( × ×
0.25% span + 5% RBW
See Table 3-1 on page 20
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.
