What is a Calibration?
A calibration is simply an oscilloscope self-adjustment. The purpose of a 
calibration is performance optimization.
There are two ways to calibrate an Infiniium S-Series oscilloscope:
•A user calibration, also known as a self calibration, includes the minimum set of 
calibrations and is intended to be run by oscilloscope users. It can include a 
time scale calibration. 
•A service calibration is performed only by Keysight Service Center technicians. 
The following section describes how to run a user (self) calibration.
