SetVSD.vi (Set Bias)

FG1Chan.vi (Function Generator)

SR.vi (Send-Receive Function)

Oscilloscope.vi (Chan1_in Read Waveform)

Procedure

  • Sub VI FG1Chan.vi sends out the bias VSG and, in series, a sine-wave signal equal to VSG/20. Set VSGinit as determined with SetVSD.vi as the VSG required to obtain ID ≈ 500 μA. This is the initial VSG in the sweep ...
