Description
Spans less than 100 MHz are checked with a frequency synthesizer
by comparing the displayed frequency span of two signals with their
known span. Wider spans are tested by tuning a synthesized sweeper
from one edge of the analyzer display to the other and measuring the
frequency change with a frequency counter.
