CW Operation
CW operation is one of the major functions of the swept CW
generator, and is easy to do using front panel keys. In CW operation,
the swept CW generator produces a single, low-noise, synthesized
frequency. Try this example: Press
Check the active entry area. It indicates:
cw:
12345.678000 MHz
The data display area indicates CW operation and the frequency
that you entered. The ENTRY ON LED is lit and the green SWEEP
LED is off.
Try other frequencies. Experiment with the rotary knob and the
arrow keys as alternate methods of data entry.
Start/Stop Frequency
The swept CW generator can sweep a frequency span as wide as
Sweep
the frequency range of the instrument, or as narrow as 0 Hz (swept
In start/stop sweep operation, the swept CW generator produces
a sweep from the selected start frequency to the selected stop
frequency.
For example:
Press
Press
The data display area indicates the start frequency and the stop
frequency. The green SWEEP LED is on (periodically off when
sweep is retracing). Because this is the active function, the active
entry area indicates:
STOP
7890.000000 MHz
Any subsequent entries change the stop frequency. To change the
start frequency, press
which remains the active function until
you press a different function key.
