Agilent / Keysight U2001B 10 MHz – 6 GHz USB Power Sensor

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.

Technical Specifications

Frequency Range: 10 MHz to 6 GHz Power Measurement Range: -30 dBm to +44 dBm Dynamic Range: 80 dB Measurement Speed: Up to 250 readings per second Measurement Uncertainty: Typically ≤1.9% at room temperature (excluding power level dependent terms) Operating Temperature Range: 0 °C to +55 °C Warm-up Period: 30 minutes required for specifications validity 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).
