Trigger is inverted for analog function generator signals #6

Closed microcontroller closed 8 years ago

microcontroller commented 8 years ago

Set up a couple of outputs connected to the input channels, and select the trigger to be on the rising/falling edge of one of the signals. You'll see that the plot starts at the falling/rising edge respectively of that signal. This is in v0.6 on Windows.

If you drag the trigger level up to say 2V and have the trigger on falling edge, then the plot will start at -2V on the rising edge, suggesting that the signal has been inverted prior to the trigger test.

Note that this does not happen with signals read in from an external source (tested with both PWM and capacitor discharge), nor does it happen with the pulse outputs, only with the analog outputs.

My mistake - sorry. I didn't see the dotted vertical line showing where along the x axis the trigger event is shown.
