  1. I have a test setup incorporating a differential voltage probe and current probe, where a math channel automatically calculates the power. 

    On re-opening this project after saving, the math function lands at "Voltage x Voltage" instead of the saved Voltage x Current". Is there a solution to save this in the waveforms config file as well? It's been causing a lot of messed up measurements when a user forgets to reset this.

    Looking forward to hear!

  2. Hey Digilent,

    I'm working through some automated measurements using the Analog Discovery 2 AWG and Scope channels, and would like to change the scope's averaging setting on the fly. I can change most of the settings using the following code: 

        // Setup scope
        Scope1.Time.Position.value = 0;
        Scope1.Time.Base.text = "5 us/div";
        Scope1.Time.Rate.text = "100 MHz";
        Scope1.Time.Samples.text = "Default";

    But can't seem to find the average setting. Is there a way to change this? Or is this fixed based on the setting in GUI? 

    Thanks in advance!

  3. I'm calculating and recording power through a load based on voltage and current measured on C1 and C2 of my Analog Discovery 2 scope, at 4kHz, for about an hour. Next to this I would like to log the temperature of the same load, or which the data is supplied through a UART.

    Would it be possible to visualize both these measurements in the same plot using a script? Perhaps by writing to a reference or math channel? We would have to be able to see all the values and plots live. 

    Thanks! David
