Making Measurements

Using This Chapter

Using This Chapter

Use this chapter to obtain an overview of how to operate the Agilent 8922M/S GSM Test Sets.

	This chapter is divided into the following sections:
	• Making Measurements
	• Agilent 8922M/S Operating Modes - explains how to configure the Agilent
	8922M/S so that measurements can be made.
	• Measurements - details how to perform the many different measurements
	available on the Agilent 8922M/S.
	• Advanced Features - advanced information for experienced users.
	To help you understand this chapter, you may wish to consult the following sources
	of information:
	• Quick Start Guide - This briefly explains the basic operating principles of the
	Agilent 8922M/S including making a call and simple measurements.
	• Typeface Conventions - Found at the front matter of this manual. This explains
	how to interpret the different typefaces used in this manual.
	• Field Types - Refer to Chapter 4, Screens. Explains in detail the different kinds
	of “fields” or areas which are displayed on the screens. Fields are mainly used for
	measurement results, data entry and access to other screens.
	• Screens -Chapter 4, provides more detailed information on each of the fields
	contained within all of the screens available on the Agilent 8922M/S.
	If you have the Agilent 8922M/S Option 010 Multi-Band Test System, refer to the
NOTE:
	appropriate Agilent 8922 Multi-Band User’s Guide for more information on making
	dual band measurements.
