Frequency Readout Accuracy
Test Limits
Frequency Readout Accuracy is equivalent to the following equation:
± (0.25% x span + 5% X RBW + 2 Hz + 0.5 x horizontal resolution)
NOTE
See results table for actual values.
Test Description
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.
