NI 5122/5124/5142 Calibration Procedure
Note
The trigger level is set to center the trigger hysteresis window at 0.0 V.
6.
Commit all the parameter settings to hardware using the niScope Commit VI.
7.
Connect the scope calibrator test head directly to the digitizer input for the channel you are
testing. Configure the calibrator to output the appropriate signal in Table 14.
8.
Wait 2,500 ms for the impedance matching and frequency of the calibrator to settle.
9.
Initiate a waveform acquisition using the niScope Initiate Acquisition VI.
