National Instruments PXI - Acquire Waveform and Check for Timeout

NI 5114 Calibration Procedure | © National Instruments | 35
6. Commit all the parameter settings to hardware using the niScope Commit VI.
7. Connect the scope calibrator test head directly to the device input for the channel you are
testing. Configure the calibrator to output the appropriate signal in Table 10.
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.
10. Acquire a waveform using the niScope Fetch (poly) VI. Select the Cluster instance of
the VI.
