HP 33120A User Guide

To phase lock to an external clock signal
The rear-panel Ext Ref In terminal allows you to synchronize one or
more function generators with an external 10 MHz signal. The following
steps show you how to configure a single instrument for synchronization
with an external signal.
1 Select the function and set the output frequency to 10 MHz.
You must select either sine or square wave since the other output
waveforms cannot be used up to 10 MHz.
10.000,000 MHz
To adjust the phase offset, you will use the front-panel menu as described
on the following page.
