The Agilent/Keysight 83203B PCS/Cellular Test Set is a specialized adapter module for CDMA base station testing, operating in conjunction with the Agilent 8921A Test Set. It delivers signal generation and analysis for IS-95 and IS-97 standards, supporting QPSK/OQPSK modulation schemes essential for cellular infrastructure validation. The module combines RF signal synthesis with calibrated noise injection and multi-domain signal analysis, enabling measurement of Walsh-coded channel power, timing relationships, phase alignment to pilot signals, and waveform quality metrics in R&D, manufacturing, and field service environments.
