Using the Agilent 11898A Module Extender
Step 3. Install the Module Extender
These steps may be done in either order: by installing the module extender in
the mainframe first, or by installing the plug-in in the bay of the module
extender first.
3 Perform calibrations necessary to ensure performance of the plug-in.
W A R N I N G Do not block the sides or bottom of the module extender during
operation. The Agilent 11898A uses convection cooling. Restricting
the airflow could damage the instrument.
C A U T I O N Use caution when installing and using the module extender to avoid damaging
the extender cable.
Selecting the trigger input location
The Agilent 11898A module extender offers two triggering options: triggering
at the mainframe, or triggering at the remote module.
• To input the trigger at the mainframe, disconnect both ends of the rigid RF
cable from the front panel of the module extender. Attach the trigger signal
to the Trigger Input connector on the front panel.
• To return to triggering at the remote module, reattach the rigid RF cable.
Note
To make sure the measurement system operates properly, there must be a good ground
connection from the module extender to the mainframe, and from the plug-in to the mod-
ule extender. The RF connectors on the rear of the modules are spring-loaded, so finger-
tighten the knurled screws on the front panels of the plug-in module and the module
extender to make sure all connectors are fully seated.
