HP 8921A Option 500 TDMA Cell Site Test System

The HP 8921A Option 500 adds the HP 83204A TDMA/CDPD Cellular Adapter to the HP 8921A to provide testing of TDMA (IS-136) base station equipment. This unit adds Pi/4 DQPSK signal generation and analysis to the powerful analog features of the standard HP 8921A. A custom screen provides control of the TDMA source and provides selection of several measurement modes, making all test results visible in one place. CDPD Mobile Data Base Station (MDBS) test features and PCS test capability can be added to the HP 8921A Option 500 TDMA test capabilities.
