PXIe-5185/5186 Calibration Procedure

27. Wait 2.5 s for the impedance matching of the calibrator to settle.
28. Adjust the vertical range using the niScope Cal Adjust Range VI.

29. Repeat steps 25 through 28 for each iteration in Table 11.
30. Disconnect or disable all inputs to the digitizer.
31. Self-calibrate the digitizer using niScope Cal Self Calibrate VI.

32. End the calibration session by calling the niScope Cal End VI.

You have finished adjusting the PXIe-5185/5186. Repeat the

Verification

section to reverify the

performance of the digitizer after adjustments.
