5. Set the reference offset:
a. Set the spectrum analyzer control:
Average 10 . . . . . . . . . . . . . . . . . .
b. Measure the peak power Ppr using the maker peak.
c.
Modify the spectrum analyzer control:
Reference offset Pr4 -- Ppr . . . . . . . . . . .
6.
Determine the reference power in --40 to --50 dBm:
Set the signal generator amplitude to --40 and --50 dBm to measure the power
as Pr5 and 6, respectively.
Signal generator amplitude Reference power
--40 dBm Pr5
--50 dBm Pr6
a. Disconnect the cable from the spectrum analyzer.
7. Modify the hookup:
a. Connect the signal generator output to the RSA3408B analyzer input.
