SWEPT FREQUENCY ACCURACY (Cont'd)
Since the circuitry that determines swept frequency accuracy
is
the same for
both
AF Mode
and Start/
Stop Mode, only Start/Stop Mode swept frequency
accuracy
is
tested.
NOTE
The spectrum analyzer
resolution
bandwidth and DUT sweep time must
be compatible
to
obtain
the desired oscilloscope
response.
