I'm playing back a 5 second long 8 kHz sine signal at 6 MHz using funcPlayPattern. (30e6 sample) The sine signal is modulated with a ramp which changes from 1 to 0 over the length of the sine signal, resulting in an amplitude of ~1 at the start of the 5 sec playback, and 0 at the end.
The issue is that if I zoom into the tail end of the 5 seconds data set on my o'scope, I can see an unexpected ~50 ns long pulse. See scope photos.
Any thoughts on what might cause that pulse and how to prevent it?
Input data:
1 sec / div
2 ms / div
50 usec / div
500 ns / div with the unexpected pulse triggered.
I uploaded the file which I use to switch back and forth between using a PlaybackOnlyExample2.pypre-recorded signal (not included) and a synthesized signal. The latter is the default setting, generating the signal at output 2.
