12. Commit all the parameter settings to hardware using the niScope
Commit VI.
13. Configure the calibrator to output the
Input Frequency
listed in
Table 12 (NI 5152), Table 13 (NI 5153), or Table 14 (NI 5154) for the
current iteration.
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 RMS
measurement using the niScope Fetch Measurement (poly) VI. Select
the Measurement Scalar DBL instance of the VI. The resulting value
is the
Measured RMS Voltage of Generated Sine Wave
used in step 17.
