This unit
The Agilent/Keysight 3709B is a Constellation Analyzer for digital radio demodulator characterization and network traffic analysis. It connects directly to I, Q, and Symbol Clock test points on radio demodulators to measure modulation quality and decode traffic across ATM, Frame Relay, and LAN networks. The instrument provides real-time hardware filtering, IP-level traffic isolation, and detailed post-capture analysis for protocol troubleshooting.
