W-CDMA TRX/PERFORMANCE TEST SYSTEM

ME7873A

For Testing System Conformance to Clause 5, 6, 7 in 3GPP TS34.121 Standards

ME7873A is the auto testing system for the Tx/Rx/Performance char-acteristic of W-CDMA mobile terminals conforming to 3GPP stan- dards. This system performs measurements conforming to Clause 5 (Transmitter test), 6 (Reception test), 7 (Performance test) in 3GPP TS 34.121 standards. The dedicated software runs on Windows 2000 and provides easy management of measurement parameters during tests and test re- sult data. PC with installed Windows

Understandable operation screen with Windows andhelp guide

? Main screen considering visual confirmability and operability Operation on main screen is done with tool bar on upper part of the screen. The tool bar is composed of icons considering understand- able operation detail. Test sequence items are displayed in the mid- dle and on the left half of the screen, varied detailed information on the right half, and test results at the bottom, all in real time during the test. Thus all necessary information in testing can be confirmed on main screen.
® 2000 is used as a system controller.Furthermore, various tests are achieved while communicating (loop- back mode) with W-CDMA mobile terminals to be tested. Also, pow- er consumption tests and temperature tests of W-CDMA mobile ter- minals are realized using DC power supply and temperature ∗

1: DC power supply and temperature chamber are needed for power con-sumption tests and temperature tests separately. For detailed information on DC power supply and temperature chamber, please contact your Anritsu sales representative. ? Extension of measured units Maximum 4 mobile terminals can be measured continuously with ME7417B-02 4 Antenna Connection Option

2: Only one unit in standard configuration. ? Auto measurement of correction value The test system that is configured various equipments requires the fre- quency characteristic compensation of input/output level. Restoration with the substitution for configuration unit and periodical maintenance such as the update of correction value can be performed in user’s site with the dedicated Correction Kit Option.
