Phase-Lock IF Gain Adjustment on the analyzer after it has been connected to the test set
as a system. This routine adjusts the R Channel receivers ALC gain to ensure phase lock
over the entire frequency range. Refer to Phase-Lock IF Gain Adjustment in the
network analyzer's online help system for details. Use the following steps to perform this
adjustment:
a. On the network analyzer, from the System menu, click Service, then Adjustments,
then IF Gain Adjustment.

firmware is a revision prior to 3.0. Follow the instructions in
page 212 to complete this adjustment.
b. Select the test set options installed.
c. No connections to the test ports are required.
d. Click Begin Adj. The adjustment takes about a minute to complete.
