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.
13. With the calibrator, output the
Negative Offset
voltage listed in Table 9
for the current iteration, with a 1 M
Ω
load impedance.
14. Wait 2,500 ms for the impedance matching of the calibrator to settle.
15. Initiate a waveform acquisition using the niScope Initiate
Acquisition VI.
16. Fetch a waveform from the digitizer and perform a voltage average
measurement using the niScope Fetch Measurement (poly) VI. Select
