The Marconi IFR Aeroflex 6934S is a precision power sensor for RF and microwave measurements from 10 MHz to 40 GHz. It delivers ±0.15 dB measurement accuracy across a dynamic range of -60 dBm to +20 dBm, making it essential for telecommunications, aerospace, and defense applications where measurement integrity is non-negotiable.
Technical Specifications
Frequency Range: 10 MHz to 40 GHz
Power Range: -60 dBm to +20 dBm (30 µW to 1 W)
Measurement Accuracy: ±0.15 dB. Linearity correction data and calibration factors are supplied for entry into compatible power meters to enhance measurement confidence.
VSWR: <1.5:1 across the operating band, with typical values of 1.12 across the full frequency range. Low input VSWR reduces measurement uncertainty.
Maximum Input Power: +20 dBm with high overload capability.
Connector: 2.92 mm (K) female, 50 Ω. MPC 2.92 mm male connectors are standard. Requires torque spanners for proper connector handling.
Calibration: Traceable to national standards. Calibration factor and linearity correction data accompany the sensor. Regular zeroing minimizes baseline drift and uncertainty.
Physical: 70 mm × 70 mm × 130 mm; 0.5 kg. Compact, lightweight design with rugged construction. Field replaceable RF assembly.
Operating Temperature: 0°C to 40°C. Designed for pollution degree 2 environments and Installation Category I supply.
