CW Operation

Start/Stop Frequency Sweep

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: 1 2 3 4 5 . 6 7 8 0 0 0 M H z

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.

The synthesizer 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 operation, the synthesizer produces a sweep from the selected start frequency to the selected stop frequency.

For example:

Press [START) @ 0 @ @ IGHz).

Press ISTOP) (7J (J (7J @ (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.
