To phase lock using the triggered burst mode
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 “triggered burst” phase-lock mode.
In the triggered burst mode, you can synchronize phase-lock signals
using an external trigger from the rear-panel Ext Trig terminal.
The following steps show you how to synchronize two function
generators at 10 kHz in the triggered burst mode.
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.
