Introduction

Introduction

Who should use the	If you are installing, commissioning, or maintaining Personal Communication
CDMA/PCS BS	Services (PCS) sites using the Code Division Multiple Access (CDMA) standard,
Test Software?	this Software will assist you in performing tests of transmitter and receiver
	performance.
Product	The HP 83236B CDMA/PCS BS Test Software is an Instrument BASIC
Description	(IBASIC) application used to set up the PCS Interface for transmitter and receiver
	measurements on CDMA base station equipment. The Software runs on the Test
	Set’s internal IBASIC controller to allow you to manually control the PCS
	Interface (which has no front-panel controls).
	This latest revision of the Software provides support for the North American PCS
	channel plans plus two proposed band definitions for use in international PCS
	networks.
	The CDMA/PCS BS Test Software is designed to run on the HP 8921A Cell Site
	Test Set using the HP 83203B or HP 83205A Cellular Adapters (an equivalent
	configuration is the HP 8921A Option 600, 601, 603). This combination of test
	equipment plus the Software is hereafter referred to as the “Test System.”
Software Operation	This Software does not perform automated measurements of a CDMA base
in Brief	station; it controls the Test System then allows you to make these measurements
	manually using the CDMA test screens. The basic steps are:
	• Set up the base station and test equipment.
	• Load and run the Software.
	• Enter information about your base station.
	• The Software configures the Test System to test.
	• Exit the Software and go to the CDMA screens.
	• Make your CDMA measurement(s).
	The first four steps are detailed in this chapter. The remaining steps are presented
	in "Making Measurements" in chapter 2.
