This chapter briefly explains the calibration of the oscilloscope. It is
intended to give you and the calibration lab personnel an understanding of
the calibration procedure and how the calibration subsystem is intended to
be used.
The commands in the CALibration subsystem allow you to change the
output of the front- panel Aux Out connector, adjust the skew of channels,
and check the status of calibration.
These CALibration commands and queries are implemented in the
Infiniium oscilloscopes:
This chapter briefly explains the calibration of the oscilloscope. It is

Oscilloscope
Calibration
Oscilloscope calibration establishes calibration factors for the oscilloscope.
These factors are stored on the oscilloscope's hard disk.
• Initiate the calibration from the "Utilities Calibration" menu.
You should calibrate the oscilloscope periodically (at least annually), or if
the ambient temperature since the last calibration has changed more than
±5
°
C. The temperature change since the last calibration is shown on the
calibration status screen which is found under the "Utilities Calibration"
dialog. It is the line labeled "Calibration
Δ
Temp: _
°
C."
See also the oscilloscope's Service Guide has more details about the
calibration.
Probe Calibration
Probe calibration establishes the gain and offset of a probe that is
connected to a channel of the oscilloscope, and applies these factors to the
calibration of that channel.
• Initiate probe calibration from the "Setup > Channel > Probes >
Calibrate Probe" menu.
