To phase lock multiple function generators
The rear-panel Ref Out and Ext Ref In terminals allow you to
synchronize multiple function generators. The diagram below shows
how to make connections for the "real-time" phase-lock mode. In the
real-time mode, the phase offset relationship is random at first. You can
adjust the phase offset "real time" from the front panel. The following
steps show you how to synchronize two function generators at 10 kHz.
Freq
1 Set both instruments to the same output frequency.
You can select sine, square, ramp, or triangle waveforms for phase-lock
operation. You cannot perform real-time phase adjustments on arbitrary
waveforms.
10.000,000 KHz
To adjust the phase offset, you will use the front-panel menu as described
on the following page.
