UNI-T UTG932/UTG962 200MSa/s Function Arbitrary Waveform Generator

[valcher]

I would like to clarify what the FPGA firmware is responsible for, the control interface?

This firmware UTG900E.bin doesn't have SRC check
We can change FW version to any we want.
Now my 3.06 changed to 1.09

Hello,

I have a noob question about the UTG 932's frequency jitter. I hope I find a correct description of the effect because I'm no native english speaker.

Since a few days I have a much better 12bit scope here and I'm fiddling around with it and my UTG 932. Above 1MHz sine coming out of the UTG I see an increasing frequency jitter (?) that leads to blurry waveforms. At the trigger point the plotted waveform line is super fine (no wonder) but it becomes more and more blurry if I scroll away from the trigger point and it maxes out 700ns away from trigger point. At 1.4µs from trigger point the wave is perfect thin again and so on.

The measured amount of frequency jitter reaches up to 3ns at a 30MHz sine wave. Is this jitter behaviour of the UTG 932 still normal? Or is my UTG defect? My old scope is still sold, so I can't compare the measurements anymore.

I've tried 50Ohm termination or not. I used different power supplies, BNC cables, scope channels, both UTG 932 outputs. All this with absolutely no effect to the frequency jitter.

Thx for your comments!

Regards
Roger
