CALibration Subsystem

Description

There are two calibrations that must be performed periodically on the test set:
• I/Q calibration
• Measurement calibration

Calibration Procedures

• I/Q calibration
This calibration is required if the baseband generator or the vector output modules are serviced or
swapped. IQ calibration should not be used as part of frequent (i.e. daily, weekly or monthly) test set
calibration.
The IQ calibration routines can be manually initiated by pressing the SYSTEM CONFIG key, then pressing
the 1 of 2 ( ) key, then pressing the Service (

• Measurement calibration
Measurement calibration takes about two minutes.
During this calibration no power should be applied to the front panel.
This calibration generates calibration data for transmitter measurements.
During calibration the internal temperature of the test set is measured and calibration data is generated
for the measurement's amplitude and frequency ranges.
An integrity bit is set true and is returned with measurement results when the measurement is
uncalibrated due to temperature drift. See
You can remotely initiate the measurement calibration routines using
page 223. The test set returns a numeric value indicating the outcome of the calibration attempt.
