Calibration
A calibration is simply an oscilloscope self- adjustment. The purpose of a calibration is
performance optimization.
There are three ways to calibrate an Infiniium oscilloscope:
• User mode, also known as normal mode, a normal calibration, user calibration, or
self calibration. User mode includes the minimum set of calibrations and is intended
to be run by oscilloscope users. The user must be logged in as an administrator to
run a self calibration. In user mode you may choose to run time scale calibrations
and interleave correction calibrations, though those selections default to not run and
they require additional equipment. A self calibration takes about 2 hours and 15
minutes.
• Service mode, also known as a service calibration. A service calibration is performed
only by Agilent Service Center technicians. In service mode the 50 Ohm input
resistance calibration is performed, in addition to everything calibrated in the normal
mode. The time scale and interleave correction calibrations are run by default, though
they can be turned off. Additional equipment is required to run a service calibration.
A service calibration takes about 2 hours and 30 minutes.
• Factory mode, also known as a factory calibration. A factory calibration includes the
full set of calibrations, including time scale and interleave correction, and other
calibrations. A factory calibration is normally performed once during production of
the oscilloscope. All of the calibration factors are stored into flash RAM on the
acquisition board so that the calibration factors determined by the factory calibration
are preserved even if the hard drive is replaced or reformatted.
