User Cal

User Cal performs an internal self-alignment routine to optimize the signal path in the oscilloscope. The routine uses internally generated signals to optimize circuits that affect channel sensitivity, offset, and trigger parameters.

Disconnect all inputs and allow the oscilloscope to warm up before performing this procedure.

54640-only - before pressing Start User Cal, connect the rear-panel Trig Out output to analog Channel 1 and Channel 2 inputs using a BNC tee adapter and equal length cables.

User Cal should be performed at least once a year, any time the ambient temperature of the oscilloscope has changed more than 10 °C since the last User Cal, or after any repair.

Performing User Cal will not invalidate your Certificate of Calibration. Successful completion of User Cal does not certify this oscilloscope with a National Institute of Standards and Technology (NIST) calibration.
