Environment:

  • OS: Windows 10 21H2
  • FW Version: v0.28
  • SW Version: Scopy v1.4.0 gitTag=f8fd4de

Describe the bug
The displayed and set memory depths are different during Run.

To Reproduce
Steps to reproduce the behavior:

  • Started the signal generator with the following configuration: 1MHz 5V Sine on Channel 1
  • Started the oscilloscope with the following configuration:Time Base = 5us, Memory depth = 8000
  • On the oscilloscope, the time base is reduced by "-" to 200 ns
    The only available memory depth setting is 320. The displayed memory depth is "352 samples at 100 Msps".

Expected behavior
The displayed memory depth is "320 samples at 100 Msps".

I realized that the "Position" setting is outside the displayed time frame. This is why more samples are required than have been set.
So this is not a bug.
