10. Fetch a waveform from the device and perform a voltage average measurement using the
niScope Fetch Measurement (poly) VI. Select the Measurement Scalar DBL instance of the
VI. This value is the Measured Positive Voltage used in step 17.
11. Configure the common vertical properties using the niScope Configure Vertical VI.
12. Commit all the parameter settings to hardware using the niScope Commit VI.
