HP 437B RF Wattmeter Technical Specifications
• Measurement Frequency Range: Wide RF frequency support from 100 kHz to 50 GHz (up to 110 GHz with some special sensor models) depending on the attached power sensor model.
• Power Measurement Range: Sensitive average power measurement from -70 dBm (100 pW) to +44 dBm (25 W) depending on the selected compatible sensor series.
• Sensor Compatibility: Industry standard for all HP / Agilent / Keysight 8480 series coaxial and waveguide RF power sensors with full compatibility.
• Dynamic Range: Total dynamic measurement range of 50 dB in 10 dB steps with a single sensor calibration or step.
• Built-in Power Reference (Power Ref): Factory-set ±0.7% accuracy reference signal output on the front panel for automatic calibration and zeroing operations 1.00 mW (0 dBm) / 50 MHz reference signal output.
• Measurement Accuracy: High instrument accuracy of ±0.02 dB or ±0.5% (±0.04 dB or ±1% for relative [REL] mode outside the range).
• Screen Resolution: Selectable 0.1, 0.01, and 0.001 dB resolution in logarithmic mode; linear (linear) mode with 1%, 0.1%, and 0.01% of full scale sensitive reading option.
• Indication Units: Absolute measurements in Watts and dBm; relative measurements in percentage (%) and dB.
• Memory and Recording: Store/Recall function to optimize sensor calibration factors and frequency curves in device memory with 10 separate measurement records.
• Duty Cycle Entry: Ability to automatically calculate and display the peak power of pulsed signals using average power measurement data.
• Military EMI / RFI Protection: Thanks to the integration of special plastic cabinet technology and metal shielding armor MIL-STD-461C structure that meets electromagnetic interference standards
• Digital Connection and Communication: standard for automatic test systems (ATE) and laboratory computer integrations HP-IB (IEEE-488) data interface port
• Size and Design: compact industrial case design, saving space in ATE cabinets, only 3 inches (approximately 88 mm) high and half-rack wide
