A synthesized signal source that is phase-locked to a known frequency
standard is used to input a signal to the analyzer. The frequency
readout of the analyzer is compared to the actual input frequency
for several different frequency settings over the analyzer's range.
The signal source is phase-locked to a standard known to be as
accurate as the analyzer's internal frequency reference to minimize
the "frequency reference error x center frequency" term of the
specification.
