To perform 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.
Performing User Cal will invalidate your Certificate of Calibration. If NIST
(National Institute of Standards and Technology) traceability is required,
perform the "Performance Verification" procedure in the Agilent
InfiniiVision 2000/3000 X- Series Oscilloscopes Service Guide using
traceable sources.
To perform user calibration:
1 Disconnect all inputs from the front and rear panels, including the
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.
Use 50W RG58AU or equivalent BNC cables when performing User Cal.
