Информация

The CMD 80 Digital Radiocommunication Tester tests mobile radiotelephones that are based on the EIA IS-95, EIA IS-95A, TSB-74, and J-STD-008 CDMA standards. The tester emulates a CDMA base station, makes a call to the mobile, and tests for all essential characteristics of a CDMA mobile telephone. The tester can measure the following key parameters: ■ FER service option 2 or 9 ■ Frame errors ■ Waveform quality ■ Error vector magnitude ■ Phase error ■ Magnitude error ■ Carrier feedthrough ■ Frequency accuracy ■ Power measurements ■ Base station signaling for mobile testing In today’s wireless environment, manufacturers are developing mobile phones to support both digital (CDMA-based) and analog (AMPS-based) wireless technologies. Installing Option 17 in the tester adds Analog Mode testing capabilities that allow you to perform analog tests on dual-mode, CDMA/Analog Mode handsets. With Option 17 (Analog Mode) installed, the tester can measure the following key analog parameters: Receiver Measurements ■ SINAD ■ Distortion ■ Frequency response ■ Hum and noise Transmitter Measurements ■ Frequency and deviation (SAT) frequency error ■ RF power ■ Distortion ■ Hum and noise ■ Frequency response ■ Modulation limits

This manual is divided into six sections. The sections are: ■ Getting Started - This section contains information you need to know before you use the CMD 80 Digital Radiocommunication Tester. ■ Operating Basics - This section describes the front and rear panel controls and connectors. It also includes an overall view of the menu structure. ■ Reference - This section describes the tests that can be performed using the tester. The section is divided into two subsections: CDMA Measurements and Analog Measurements. Analog Measurements provides analog test information for testers with Option 17 (Analog Mode) installed. ■ Appendices, - Five appendices are included: * Appendix A: Specifications describes the characteristics of the tester. « Appendix B: Remote Control describes the general use of and gives programming information for the remote control interfaces. « Appendix C: Remote Control Commands lists the specific commands used to operate the tester remotely. ■ Appendix D: Remote Control Command Tables is a tabular listing of remote control commands and related information. ■ Appendix E: Special Commands describes special-purpose remote commands that provide for nonstandard operation of the tester. ■ Glossary - The glossary describes technical terms and acronyms that might not be familiar. ■ Index ~ The index provides a quick way to find information relating to a particular subject.
