NI 5122/5124/5142 Calibration Procedure
5.
Ground the calibrator.
6.
Wait 500 ms for the calibrator to ground its output to channel 1 of the digitizer.
7.
Adjust the vertical range using the niScope Cal Adjust Range VI.
8.
Using a BNC cable, connect REF FREQUENCY OUTPUT on the back of the calibrator to
the channel 0 input of the digitizer. Make sure the output of the reference frequency is
enabled and set to 10 MHz. If you are not using a Fluke 9500B/Wavetek 9500 calibrator,
connect a precise 10 MHz, 1 Vpk-pk sine or square wave source to channel 0.
9.
Adjust the sample rate using the niScope Cal Adjust VCXO VI.
