Calibration Overview

Calibration Overview

C A U T I O N

The input circuits can be damaged by electrostatic discharge (ESD). Avoid 
applying static discharges to the front-panel input connectors. Before 
connecting a coaxial cable to the connectors, momentarily short the center and 
outer connectors of the cable together. Avoid touching the front panel input 
connectors without first touching the frame of the instrument. Be sure that the 
instrument is properly earth-grounded to prevent buildup of static charge. It is 
strongly recommended that an antistatic mat and wristband be used when 
connecting to electrical channel inputs. 

Calibration interval

Agilent Technologies recommends that the factory calibration be performed 
on a periodic basis. Agilent Technologies designs instruments to meet specifi-
cations over the recommended calibration interval provided that the instru-
ment is operated within the specified operating environment. To maintain 
specifications, periodic recalibrations are necessary. We recommend that the 
plug-in module be calibrated at an Agilent Technologies service facility every 
12 months. Users are encouraged to adjust the calibration cycle based on their 
particular operating environment or measurement accuracy needs.

Required warm-up time 

The instrument requires a 1 hour warm-up period before any of the calibra-
tions mentioned in this chapter are performed. It is not enough for the instru-
ment to be in the standby setting. It must be turned on and running for the 
entire hour. 

Remote operation 

Remote programming commands for calibrations are included in the 

Agilent 83480A/Agilent 54750A Programming’s Guide

. Performing calibra-

tions remotely is slightly different than the operation of front-panel calibra-
tions.
