User Calibration
Perform user-calibration:
• Every two years or after 4000 hours of operation.
• If the ambient temperature is >10° C from the calibration temperature.
• If you want to maximize the measurement accuracy.
The amount of use, environmental conditions, and experience with other
instruments help determine if you need shorter User Cal intervals.
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.
Performing User Cal will invalidate your Certificate of Calibration. If NIST (National
Institute of Standards and Technology) traceability is required perform the
procedures in
in this book using traceable sources.
To perform User Cal
1
Disconnect all inputs from the front and rear panels, including the digital
channels cable on an MSO, and allow the oscilloscope to warm up before
performing this procedure.
Before you start the adjustments, let the oscilloscope and test equipment warm
up for at least 30 minutes.
2
Press the rear-panel CAL button to disable calibration protection.
3
Connect short (12 inch maximum) equal length cables to each analog channel’s
BNC connector on the front of the oscilloscope. You will need two equal-length
cables for a 2-channel oscilloscope or four equal-length cables for a 4-channel
oscilloscope.
