Frequency Response

This is a port of my older frequency response application to Pawn. It features a few improvements:

  • Configurable measurement range 10Hz - 200kHz for sinewave and 10Hz - 20MHz for square wave. (though measurements over 2MHz are quite inaccurate)
  • Movable cursor to read results in numeric form.
  • Ability to use Channel B as reference input to improve precision.


Button 1: Start measurement. Hold for 1 second to clear screen before the measurement.

Button 2: Open the Save-submenu. Supported formats are screenshot in BMP format and raw data in CSV format.

Button 3: Open configuration dialog.

Button 4: Quit.

Scroller 1: No action.

Scroller 2: Move the cursor. Current values are shown at the bottom of the screen.

You can’t perform that action at this time.
