The HP/Agilent 8484A Power Sensor is a precision RF power measurement instrument engineered for low-level signal detection across microwave frequencies. It delivers exceptional sensitivity and accuracy in telecommunications, research, and aerospace environments, capable of resolving power levels as low as 0.1 nanowatt while maintaining stability in complex signal conditions.
Technical Specifications
• Frequency Range: 10 MHz to 18 GHz
• Power Measurement Range: −70 dBm to −20 dBm (0.1 nW to 10 µW)
• Maximum Average Power: 200 mW
• Maximum Peak Power: 200 mW
• Impedance: 50 ohms nominal
• RF Connector: Type N Male (military specification)
• Dimensions: 36 mm × 44 mm × 133 mm (excluding attenuator)
• Weight: 0.4 kg (excluding attenuator)
– Key Features
• Sensitivity to 0.1 nW enables measurement of extremely weak signals. Exceptional accuracy and stability in multi-tone, modulated, and harmonic-rich environments. Low standing wave ratio minimizes mismatch uncertainty. Noise and drift specifications less than 5% of full scale on the 300 pW range. Individual NIST/NBS-traceable calibration certificate supplied with each unit. Includes HP 11708A 30 dB Reference Attenuator (maximum SWR 1.05 at 50 MHz) for field recalibration. Requires one-hour thermal stabilization before recalibration procedures.
– Typical Applications
• RF power monitoring in telecommunications infrastructure
• Low-level signal measurement in research and development
• Aerospace and defense power characterization
• Multi-carrier and modulated signal assessment
