The Keysight U2001B is a USB-connected power sensor for direct average power measurement across 10 MHz to 6 GHz. It delivers -30 dBm to +44 dBm measurement capability with an 80 dB dynamic range, supporting both continuous wave and modulated signals. The sensor eliminates external power supplies by drawing power directly from a PC or laptop USB port, making it ideal for field and bench applications in wireless communications, aerospace, and defense environments.

Dual Measurement Paths:
• Low Power Path: -30 dBm to +23 dBm
• High Power Path: +23 dBm to +44 dBm
• Automatic switching at +23 dBm with ±0.5 dBm hysteresis
– Key Features
• Internal zeroing without DUT disconnection reduces test time and sensor wear
• External zeroing recommended for measurements below -30 dBm
• Supports internal and external trigger measurement modes
• Internal triggering responds to burst signal envelope, eliminating external trigger requirement
• Trace display functionality provides signal envelope visualization for gate placement and trigger setup
• SCPI-compatible for automated system integration
– Typical Applications
Wireless communications, aerospace, and defense power measurement and characterization.
– Compatibility & Integration
USB interface supplies power and handles data transfer. Controllable via Keysight BenchVue software. Operates within 15% to 75% relative humidity at calibrated specifications (25 °C ± 10 °C).
