Agilent/Keysight U2049XA

The Keysight U2049XA is a LAN-based power sensor delivering peak and average power measurements across 10 MHz to 33 GHz with 90 dB dynamic range. Operating from −70 dBm to +20 dBm, this sensor executes time-gated, pulse parameter, and free-run measurements with real-time rates up to 50,000 readings per second. Square-law diode operation ensures accurate broadband modulated signal measurement. Internal zero and automatic calibration reduce measurement uncertainty, while long-term drift performance enables unattended automated monitoring.

– Compatibility & Integration

Connectivity via standard LAN with PoE eliminates need for dedicated power infrastructure. Requires PoE-enabled port; standard PC or instrument LAN ports are insufficient. Includes 5 ft (1.5 m) LAN cable, two BNC-to-SMB trigger cables (50 Ω, 1.5 m each), calibration certificate, and documentation.
