CW Operation and
Start/Stop
Frequency Sweep
CW Operation
CW operation is one of the major functions of the synthesizer, and is
easy to do using front panel keys. In CW operation, the synthesizer
produces a single, low-noise, synthesized frequency. Try this example:
Press(CW)(iJ@(J@@@@(7J@IGHz).
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 synthesizer can sweep a frequency span as wide as the frequency
Sweep
range of the instrument, or as narrow as 0 Hz (swept CW).
In start/stop sweep operation, the synthesizer produces a sweep from
the selected start frequency to the selected stop frequency.
For example:
Press [START)
@
0

IGHz).
Press

(GHz.
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 FREQUENCY: 7890.000000 MHz
Any subsequent entries change the stop frequency. To change the
start frequency, press (START), which remains the active function until
you press a different function key.
