IF Gain Adjustment

IF Gain Adjustment
This procedure is for N8362A and N8364A PNA network analyzers that have firmware
revisions less than Revision 3.0.
It is recommended that the Service IF Gain Adjustment test be run before using the test set.
This routine adjusts the R Channel receivers ALC gain to ensure phase lock over the entire
frequency range of the PNA Series Network Analyzer. Connect the test set to the analyzer
before adjusting the IF gain.
When the analyzer is removed from the test set for service, or for other
NOTE
applications that do not require the test set, the IF gain adjustment must be
run again to return the R Channel receiver ALC gain back to normal.
