Operation

Power Sweep Operation

The power sweep function allows the power output to be swept
(positive or negative) when the synthesizer is in the CW frequency
mode. The power output of the synthesizer determines the maximum
leveled power sweep that can be accomplished. For this example refer
to the “Menu Map” section.

Zero and calibrate the power meter.

Connect the instruments as shown in Figure

Press

Press

(

P O W E R

Press (SWEEP

[SINGLE).

Set the power meter to dB[REF] mode.

The synthesizer is ready to produce a 4

CW signal at 0

power out, with a 2 second sweep rate whenever a single sweep is
executed. The power meter is ready to measure the power level
relative to a starting point of 0

Press POWER

Select Power Sweep and enter

(asterisk on).

Press

Watch the relative power indication on the power meter. At the end
of the sweep the power meter indicates

The active entry area

on the synthesizer indicates:

POWER SWEEP:

7.00 dB/SWP

Now enter

(power sweep is still the active entry

function).

This time the power meter indicates less than the power sweep

requested. Note that the synthesizer is unleveled,

UNLVD.

This

happens because the synthesizer’s output power at the start of the
sweep is 0

and the requested power sweep takes the synthesizer

beyond the range where it is able to produce leveled power. The
range of the power sweep is dependent on the ALC range and can be
offset if a step attenuator (Option 001) is present.

Select Power Sweep to turn this function off (no asterisk).

Press

On the power meter, press dB[REF] to reset the reference level.
