Run the .exe installer
Plug the Analog Discovery 3s into the laptop and open up the Waveforms software.
Set up the circuit that connects the Analog Discovery 3 like this circuit diagram:
The actual circuit will look something like this:
For our purposes, click on Tracer (for IV Characterization).
Click on drop down to select transistor type.
Select “No Adapter”
Select “Measure Id/Vgs” and set the ranges for the Vgs and Vds.
Select step-size/no. of steps for both voltages.
Click play (in the top right corner) and watch the magic!
I-V Curve for ZVN3310A Transistor on Curve Tracer (replace this image with our chip curves).
Can adjust current compliance for Gate if needed. (below the main toolbar, right above the graph).
