NI 5450 Calibration Procedure
58

9.
Wait 2,500 ms for the impedance matching and frequency of the
calibrator to settle.
10. Initiate a waveform acquisition using the niScope Initiate
Acquisition VI.
11. Fetch a waveform from the digitizer using the niScope Fetch (poly) VI.
Select the Cluster instance of the VI.
If the digitizer does not time out, the digitizer has passed this portion
of the verification. If the digitizer times out, you must call niScope
Abort VI (
niScope_Abort
function) to end the acquisition.
12. Repeat steps 2 through 11 for each iteration in Table 17.
13. End the session using the niScope Close VI.
You have finished verifying the trigger sensitivity for the
NI 5152/5153/5154.
