CW Operation and

Frequency Sweep
CW Operation
CW op eration is one of the ma jor functions of the swept signal
generator, and is easy to do using front panel keys. In CW op eration,
the swept signal generator pro duces 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 o.
Try other frequencies. Experiment with the rotary knob and the
arrow keys as alternate metho ds of data entry.
Start/Stop Frequency
Sweep
The swept signal generator can sweep a frequency span as wide as
the frequency range of the instrument, or as narrow as 0 Hz (swept
CW).
In start/stop sweep op eration, the swept signal generator pro duces
asweep from the selected start frequency to the selected stop
frequency.
For example:
Press

The data display area indicates the start frequency and the stop
frequency. The green SWEEP LED is on (p erio dically o when
sweep is retracing). Because this is the active function, the active
entry area indicates:
--> STOP FREQUENCY: 7890.000000 MHz
Any subsequententries change the stop frequency.Tochange the
start frequency, press
4

, which remains the active function until
you press a dierent function key.
