The Agilent/Keysight 8922M is a GSM Radio Test Set purpose-built for high-volume manufacturing and device validation. This single-unit instrument integrates RF generation, RF analysis, power measurement, audio analysis, and GSM base station emulation to streamline production testing workflows. The 8922M delivers one-button call setup, fast burst BER measurements, and repeatable performance across GSM Phase II compliance testing, including Enhanced Full-Rate Speech and High-Speed Circuit Switched Data (HSCSD).
