START/STOP FREQUENCY
To select zero span, press [F) m a
Video trigger can be used to trigger on the waveform.
The sweep time control can be adjusted to change the
horizontal scale.
START/STOP FREQUENCY
Another way to adjust the frequency range is by using START/STOP FREQUENCY instead of CENTER FRE-
QUENCY and FREQUENCY SPAN. Activating START FREQ or STOP FREQ causes both to read out in place of
CENTER FREQUENCY and SPAN on the CRT START FREQ sets the left graticule frequency and STOP FREQ
sets the right graticule frequency; both are mutually exclusive with CENTER FREQUENCY and FREQUENCY
SPAN.
The INSTRUMENT STATE keys, w and m , select a start/stop frequency from 0 to 2.5 GHz and 2 to 22
The maximum start/stop frequency span allowable is 22 GHz; the minimum span is 100 Hz and zero span
(START FREQ = STOP FREQ) .
Start/Stop frequency readout resolution is 1% of the span (span = stop frequency - start frequency). Both start
or stop frequencies can be entered with 1 Hz resolution.
DATA Entry with START/STOP Frequency
or
24 Manual Operation
Changes the start or stop frequency. The amount of change per turn is a
constant percentage of the frequency span.
Changes the frequency by one tenth of the total frequency span.
Exact start or stop frequencies can be entered. The number of digits read out
depends upon the frequency span.
