4. Adjust the amplitude on the sythesized sweeper until the marker
amplitude on the analyzer reads 0 dBm +/– 0.10 dB. Record the
synthesized sweeper output level as the reference in Table 3-7 on
page 3-42.
NOTE 75 Ω Input only. Adjust the synthesized sweeper amplitude until the
analyzer’s marker reads 48.8 dBmV +/– 0.10 dB.
5. On the analyzer, press the following keys:
Single
Peak Search
Marker, Delta
6. Record the marker delta reading in Table 3-7. At each new
synthesized sweeper power level, press
Single, Peak Search, and
record the marker amplitude level.
