NI 5450 Calibration Procedure
5.
Configure an edge trigger using the niScope Configure Trigger (poly)
VI. Select the Analog Edge Ref Trigger instance of the VI.
6.
Commit all the parameter settings to hardware using the niScope
Commit VI.
7.
Connect the scope calibrator to the digitizer input as follows for the
current
Trigger Source
value from Table 17:
•
Channel 0 and Channel 1—Connect the scope calibrator directly
to the digitizer input channel as specified by the
Trigger Source
value from Table 17 for the current iteration.
•
External Trigger—Connect the scope calibrator to the external
trigger channel (TRIG).
8.
Configure the scope calibrator to output the signal listed under the
Calibration Test Limits
or the
Published Specifications
in Table 17.
