The Agilent/Keysight U2004A is a USB power sensor that delivers accurate RF and microwave power measurements from 9 kHz to 6 GHz across an 80 dB dynamic range. Direct USB connectivity to a PC eliminates the need for external power meters, enabling simplified benchtop and field deployments without sacrificing measurement speed or precision.
– Technical Specifications
Frequency Range: 9 kHz to 6 GHz
Power Measurement Range: -60 dBm to +20 dBm
Maximum Power Handling: +25 dBm average (5 VDC), +33 dBm peak (< 10 µs)
Dynamic Range: 80 dB
Measurement Speed: Up to 250 readings/second (buffered mode)
Connector: Type-N male
– Key Features
• Dual measurement modes — Average-only mode optimized for wide dynamic range with external TTL trigger control; Normal 2 mode for time-gated average power measurement with internal RF-based or external TTL triggering
• Automatic path switching at -7 dBm with ±0.5 dBm hysteresis and ±0.5% offset accuracy (typical)
• Internal zeroing capability eliminates external calibration and reduces test time; measurements can proceed while connected to the DUT without powering down
• Low-power path: -60 dBm to -7 dBm | High-power path: -7 dBm to +20 dBm
• Plug-and-play USB connectivity with minimal power draw from the host port
• Compact, lightweight design reduces bench and rack footprint
– Typical Applications
• RF and microwave power characterization across benchtop and field environments
• Burst and time-gated signal power measurement
• Device Under Test (DUT) power monitoring during operation without shutdown cycles
– Compatibility & Integration
• Software: Keysight BenchVue (including BV0007B Basic Power Meter/Sensor Control and Analysis App)
• System control: SCPI command support for integration with PC-based and Keysight USB instrument systems
• Included: Power sensor cable, trigger cable (BNC male to SMB female, 50 Ω, 1.5 m), calibration certificate, documentation CD-ROM, instrument control DVD
