Signal Generator: Skewed Square Waveform from 5MHz up tp 30MHz #901

Closed HRosete closed 4 years ago

HRosete commented 4 years ago

Environment:

Describe the bug The preview of the square waveform skews into somewhat a trapezoidal waveform from frequencies 5MHz up to 30MHz. image

To Reproduce Steps to reproduce the behavior:

  1. Go to 'Signal Generator.'
  2. Click on 'Waveform' and select 'Square.'
  3. Set the frequency anywhere between 5MHz and 30MHz.
  4. Increment/Decrement the frequency using the + and - keys and see the waveform skew.

Expected behavior The square waveform must retain its shape even if the frequency's changed.

Additional context (can't seem to upload the .ini file)

This is the expected behavior. Plot sample rate is 75MHz (the same as DAC sample rate)

Thank you for the clarification, Adrian!
