Power Level Operation
The synthesizer can produce leveled power for CW, swept frequency,
or power sweep operation. The selected power level can range from
-20
dBm
(-110
dBm
for option 001 synthesizers) to
+25
dBm.
For practice: Press (POWER LEVEL) I-]

POWER LEVEL: -20.00
dBm
If the selected power level is beyond the range of the synthesizer, the
closest possible power is shown in both the data display area and the
active entry area. If the selected power level exceeds the maximum
leveled power the synthesizer is able to produce, the unleveled
message UNLVLED appears on the message line. Experiment with the
rotary knob and the arrow keys as alternate methods of data entry.
Sweep Time Operation
In typical applications the sweep time can vary tremendously, from
milliseconds in a network analyzer system, to more than a minute in
thermistor-based power meter systems. For this example, refer to the
“MENU MAP” section.

Watch the green SWEEP LED, it blinks every 2.5 seconds. The LED
blinks at each retrace.
For the fastest sweep speed for which all specifications are
guaranteed, the synthesizer must be in automatic sweep time
selection.
