Power Sweep Operation

The power sweep function allows the power output to be swept
(positive or negative) when the swept signal generator is in the
CW frequency mode. The power output of the swept signal
generator 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 l-10.

Set the power meter to dB[REF] mode.
The swept signal generator is ready to produce a 4 GHz CW signal
at 0 dBm 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 dBm.
Press POWER (jZK).
Select Power Sweep and enter 0 (dB0) (asterisk on).
Press (SINGLE).
Watch the relative power indication on the power meter. At the end
of the sweep the power meter indicates +7 dB. The active entry area
on the swept signal generator indicates:
Now enter @ @ [lecm,) (power sweep is still the active entry
function).
Press (SINGLE).
This time the power meter indicates less than the power sweep
requested. Note that the swept signal generator is unleveled,
This happens because the swept signal generator's output power
at the start of the sweep is 0 dB and the requested power sweep
takes the swept signal generator 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).
