Service
Service functions are accessed using the 85102 Service and XF Test Set
Service menus, described below.
85102 Service [SYSTEM]{MORE} {SERVICE FUNCTIONS}{85102 SERVICE} calls up the menu shown on
the right of the figure below:
Figure 3-21 Service Functions Menu, 85102 Service Submenu,
and Equivalent GPIB Commands
This menu includes those service functions which apply specifically to the
network analyzer, rather than to the test set.
These functions are intended to be used only by Agilent service engineers.
NOTE “85102” refers to the IF/detector section of the 8510C network analyzer,
which is placed below the display/processor section.
IF Gain Submenu The {IF GAIN} softkey calls up the IF gain submenu, which is identical in the
8510XF to the submenu which appears in the standard 8510C operating
system under
[SYSTEM] {MORE} {SERVICE FUNCTIONS} {IF GAIN}. This submenu
makes it possible to disable the automatic gain control system which
normally regulates IF levels within the network analyzer, and specify a fixed
gain setting instead.
