Preparing to Take Measurements 2

Agilent U7232A DisplayPort Electrical Performance Compliance Test Application 21

Calibrating the Oscilloscope

If you haven’t already calibrated the oscilloscope and probe, see

Chapter 24, “Calibrating the Infiniium Oscilloscope and Probe.

NOTE

If the ambient temperature changes more than 5 degrees Celsius from the calibration

temperature, internal calibration should be performed again. The delta between the

calibration temperature and the present operating temperature is shown in the

Utilities>Calibration menu.

NOTE

If you switch cables between channels or other oscilloscopes, it is necessary to perform

cable and probe calibration again. Agilent recommends that, once calibration is performed,

you label the cables with the channel on which they were calibrated.
