Calibration and Preventive Maintenance
Calibration Overview
Calibration is recommended for VXI modules or individual instruments on
an annual basis. Typically this requires removing the VXI module(s) or
instruments from the system for calibration.
The Agilent E6171A/B Measurement Control Module is automatically
adjusted by the system software. When the Agilent TestExec SL software is
started, the automatic adjustment constants are down-loaded and the time
stamp is checked. If there has been more then 30 days since the last time the
automated adjust has been run, a dialog box will ask you if you would like
to run the automatic adjustment. This adjustment should be run whenever
the system configuration changes, the E6171A/B is replaced, another VXI
module has been replaced, there is a greater then 5° C temperature change,
or every 30 days. The adjustment procedure uses the Agilent E1411B to
determine the correction constants.
Customers have the choice of having the VXI modules (except the Agilent
E6171A/B which must be calibrated as part of the system) or instruments
calibrated before leaving the factory or upon installation. Either service is
available at an extra charge. This service will need to be quoted by the local
Agilent Field office.
Exchange VXI assemblies from Agilent's Support Materials Organization
are calibrated.
