7. Wait 500 ms for the calibrator to ground its output.
8. Initiate a waveform acquisition using the niScope Initiate Acquisition VI.
9. 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.
Compare the resulting average voltage to the value listed in the Published Specifications
column in Table 5 that corresponds to the settings used. If the result is within the selected
test limit, the device has passed this portion of the verification.
10. Repeat steps 2 through 9 for each iteration in Table 4.
11. Move the calibrator test head to device input channel 1 and repeat steps 2 through 10 for
every configuration in Table 4, changing the value of the channelList parameter from
"0"
to
"1".
12. End the session using the niScope Close VI.
