Hi David-A!
I've reproduced the problem, see screenshots in attachment.
For experiment purity I downloaded example project from https://decibel.ni.com/content/docs/DOC-26352 again.
No code modification, no any other device than scope connected to my AT-1212(not AT-1120, but i think they are quite similar).
I changed only amplitude value from 1.00 V to 0.50 V in appropriate control
The problem appears rarely. This shots were made only on 20th launch of the example VI.
Also there are some sinusoide's distortion on the second picture

Hi Kostyuk.a,
We are going to try and see if we can reproduce the issue here on our end for further investigation. Thank you for your patience.
