Function Generator Sync Problem

[kolabuzlu]

Hi everyone,

My function generator has four outputs. Two of them are main outputs Channel A and B, other two are TTL outputs Channel A and B.
I do want TTL Ch A to sync with main Ch A signal, but it does not. The two act like independent from each other.
Where am I missing? What can cause the problem?

Please help.

Best regards to all.

What is the make and model number of your FG?

[kolabuzlu]

It's a cheap, Chinese-made FG.

It's a cheap, Chinese-made FG.

Is it possible that they swapped the digital outputs, and the "other" one is synchronous with CH1?

They may did. I'll check and post here.
