Linear Mode Procedure

1. Set the power level on the synthesized sweeper to –30 dBm by pressing

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
synthesized sweeper output power and the analyzer's reference level will be changed in
10 dB steps.)
5. On the analyzer, press
