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-] @ @ (dB(mL). The active entry area shows:

--> 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.

Press @%Ki) @ [GHz).

Press ISTOP) @ (GHz).

Press lsWEEP @ 0 (ZJ (,,,).

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.

Refer to menu map 8.

Press SWEEP [MENU).

Select SwpTime Aut0 .

Notice that the active entry area indicates:

--> SWEEP TIME: 100.0 mSec AUTO

When the synthesizer is in automatic sweep time selection, the active entry area displays AUTO along with the current sweep time. Faster sweep speeds than this are possible, turn the rotary knob counter-clockwise until the display no longer changes. Notice that AUTO is no longer displayed
