Calibrating and Adjusting

2000/3000 X-Series Oscilloscopes Service Guide

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

Chapter 2

in this book using traceable sources.

To perform User Cal

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.

Press the rear-panel CAL button to disable calibration protection..

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.
