SF Free Space Field Sensors – Precision Electromagnetic Field Measurement

Reliable Measurement of Fast Pulsed Electromagnetic Fields

The SF Free Space Field Sensors by Montena are high-precision instruments designed for the accurate measurement of fast pulsed electric (E-field) and magnetic (B-field) fields. These sensors provide interference-free and passive operation, making them ideal for EMC testing, high-voltage applications, and RF measurement environments.

Key Features & Benefits

Wide Frequency Response: Measures fields up to 10 GHz, capturing transient pulses with high accuracy.
Passive Operation: No external power source is required, ensuring long-term reliability.
High Sensitivity & Precision: Optimized for fast-rise time measurements in EMC and RF testing.
Balanced to Unbalanced Signal Conversion: Compatible with baluns and passive integrators for enhanced signal processing.
Fiber Optic Compatibility: Allows long-distance, noise-free transmission to measurement equipment.
Compact & Durable Design: Lightweight and robust for easy installation in test setups.
