... In th AWG mode, the waveform is clipping on the negative side as I increase the amplitude to near the 2.5V limit or if I set a negative offse...
The jitter of the AFG is pretty horrendous, specially with frequencies over 1MHz. Is that normal?
Waveforms presents some artifacts under various settings of frequencie and amplitude

Hi Amy,
I have a few more observations, if you allow me. Please, don't get me wrong, I really like ...
But about CH2 noise, our engineer has not come up with a good idea yet.

Sir, about the AWG burr, there is a solution to deal with.
1. Replace the resistance to 1.5KΩ in th ...

Dear Amy,
thanks for your efforts to get this issue resolved.

I noticed yet another noise pattern of the scope, caused by the AWG, and affecting both scope channe ...
Finally I had time to test the proposed modification. I've changed R61 to 1.5K as indicated, installed the last FW (20190312001) and run the calibration. I noticed some improvement but I still get glitchs in the waveforms

In the first picture the AWG is off, in the second AWG is set to sine wave, 1MHz, 1V and turned on. There is nothing conected to the inputs.

That's really heavy!
I've never seen such a high amplitude on mine.
Does it make a difference in your case whether the AWG is open or driving a load?
Was USB connected to PC or power supply?
Does the noise amplitude (in div units on the display) change with V/div setting of CH2?
Sorry, our Engineer hasn't given me a conclusion yet. I'll urge him to reply next week.

Hi, about the waveform burr, our engineer modify the FPGA.Please use this to update.

Hi Amy, sometimes it does not read what the frequency is, so I have to use the cursor.
The cursor ca ...
