What is the difference between “Trigger out” and “Sync out”?

What is the difference between “Trigger out” and “Sync out”?

Trigger and Sync Out are almost the same. They are only different in the burst mode, in inifinte-cycle mode.

Figure 1: Trigger out mode

Scope CH1 ->AFGCH1
Scope CH2 ->AFGTrigger out
Scope CH3 ->AFGTrigger in(with T connector)

In this case a Trigger out signal will happen every cycle. For frequencies higher than 5 MHz Trigger out will not happen every cycle but will be in sync with the output waveform.

Figure 2: Sync out mode

Scope CH1 ->AFGCH1
Scope CH2 ->AFGSync out
Scope CH3 ->AFGTrigger in(with T connector)

The Sync out is only one pulse. The Sync mode is used for creating a Master-Slave setup with two AFG products.
