Calibration Overview
This chapter describes the calibration of the mainframe and the plug-in mod-
ules. It is intended to give you, or the calibration laboratory personnel, an
understanding of the various calibration procedures available, and how they
were intended to be used. There is a description of the calibration menu
included in the manuals provided with the plug-in modules and probes.
Proper calibration is critical to measurement accuracy and repeatability. The
Agilent 54750A/83480A and their associated modules and accessories require
that both factory and user calibrations be implemented at the recommended
intervals in order to perform measurements at their published specifications.
This chapter is divided into three sections. The first section describes factory
calibrations. A factory calibration consists of verifying instrument perfor-
mance to all specifications. If an instrument fails to meet specifications,
adjustment or repair may be necessary. For most users, this will mean ship-
ping the instrument back to an authorized service center. Some users may
purchase the required instrumentation and perform the factory timebase cali-
brations themselves using the optional Agilent 83480A, 54750A Service
Guide.
The second part of the chapter addresses calibrations that are routinely per-
formed by the end user. Subsections in each of the two main sections discuss
the individual calibrations. In addition, there are summary tables at the end of
each of these sections summarizing the main areas addressed. The third part
of the chapter consists of a complete calibration summary table. Both factory
and user calibrations must be performed regularly in order to ensure proper
measurement accuracy and repeatability.
