The Agilent Technologies 83206A TDMA Cellular Adapter adds TDMA DAMPS/DCCH (IS-136) mobile measurement capability to the Agilent Technologies 8920B RF Communications Test Set. The Agilent 83206A TDMA Cellular Adapter (Agilent 8920B-800) provides a complete π/4 DQPSK signal generator, π/4 DQPSK modulation analyzer, data source, and BER analyzer for TDMA measurements on DAMPS (IS-54) and DCCH (IS-136) phones. The 83206A replaces the Agilent 83201B TDMA cellular adapter (Agilent 8920B-500) for making measurements on TDMA dual-mode DAMPS phones, adding digital control channel test features to fully characterize DCCH phones.
