10. Acquire a waveform using the niScope Fetch (poly) VI. Select the Cluster instance of
the VI.
11. If the digitizer does not time out, the digitizer has passed this portion of the verification. If
the digitizer does time out, you must call the niScope Abort VI to end the acquisition.
12. To verify the trigger sensitivity on channel 1, repeat steps 2 through 11 using the values in
Table 14, iterations 5 through 8. Make the following changes:
•
Change channelList to
"1"
in steps 2, 3, and 10
• Connect the calibrator test head to channel 1 in step 7
13. To verify the trigger sensitivity on the external trigger channel, repeat steps 2 through 11
using the values in Table 14, iterations 9 through 12. Make the following changes:
•
Change the channelList to
"0"
• Connect the calibrator test head to the external trigger channel (TRIG) in step 7.
14. End the session using the niScope Close VI.
You have finished verifying the trigger sensitivity for the NI 5122/5124/5142.
