Reference Level Accuracy
4. Now that the reference has been established in step 4, adjust the
synthesized sweeper power level and the analyzer reference level
according to Table 3-5. (The synthesized sweeper output power and
the analyzer’s reference level will be changed in 10 dB steps.)
5. On the analyzer, press
Single and wait for a sweep to finish. Press
Peak Search, Marker, Delta.
6. For each new synthesized sweeper power level and analyzer
reference level change, press the following keys on the analyzer:
Single
Peak Search
Record the Analyzer Marker Amplitude reading in Table 3-5.
