Configuring the pattern generator
This procedure shows you, step-by-step, how to configure the Agilent 70841B
pattern generator settings for the performance tests and adjustment proce-
dures. It is assumed, that the Agilent 70311A clock source is configured in the
modular measurement system (MMS) mainframe as a slave to the pattern gen-
erator module. This allows you to change the clock source’s frequency from
the pattern generator. If your clock source is not configured as a slave module
to the pattern generator, you can still set its frequency using its own menu.
Consult the user manuals for these products to learn how to correctly install
and operate them.
