3. Adjust the amplitude on the synthesized sweeper until the marker amplitude on the
analyzer reads –30 dBm +/– 0.10 dB. Enter the synthesized sweeper power level as the
Synthesized Sweeper Amplitude reference in
NOTE
Under these analyzer conditions, the sweep time is 1.7 seconds. Therefore,
the marker amplitude updates are fairly slow when adjusting the synthesizer
output power.
4. Now that the reference has been established in step 4, adjust the synthesized sweeper
power level and the analyzer reference level according to
(The
synthesized sweeper output power and the analyzer’s reference level will be changed in
10 dB steps.)
5. On the analyzer, press
Single

6. For each new synthesized sweeper power level and analyzer reference level change,
press the following keys on the analyzer:
