How do you properly setup a frequency sweep with a digital signal generator and a RIGOL oscilloscope?
I've got a setup similar to one in this video: https://www.youtube.com/watch?v=ni07A7sZCPM, showing it's possible. Still, I can't find anywhere a clear instruction on how to set a fixed trigger time just like the author of the video did.
So, I've got very popular Rigol DS1054Z (in the video, the author uses a RIGOL DS1102E) and a FeelTech FY3200S function generator, which is a cheap generator from china, with good reviews in general.
Since it's a digital generator, it's providing only a TTL square wave, and no ramp is available. It would seem, the author of the video only has a single wire connected to the oscilloscope anyway. Please advise.
Your help is greatly appreciated. Thank you.
