EMSense™ Platinum E-Field Probe

ETS-Lindgren’s EMSenseTM Platinum Laser-powered Electrical Field Probe is designed for applications where speed and accuracy are critical. This probe is ideal for demanding EMC and RF testing environments, especially where pulsed or rapidly changing fields are present, such as in radar pulse analysis and mode-stirred chambers. With its exceptionally fast performance—capable of up to 2 million full measurements per second and 6 million samples across all three axes—the EMSense Platinum delivers real-time insight into highspeed field variations. Unlike traditional probes that rely on buffered data, the Platinum Probe ensures every reading reflects the actual field strength at the exact moment it’s requested, preventing data lag and enabling stable operation of automated test routines.

This probe offers a broad frequency range from 20 MHz to 18 GHz and supports a wide dynamic field strength measurement range from 2 to 1,000 V/m, with a maximum damage threshold of 1,500 V/m. High resolution down to 0.01 V/m and tight linearity specifications (± 1 dB ± 0.5 V/m) ensure accuracy across a wide range of applications. Its anisotropic performance is equally impressive, with deviations limited to ± 0.5 dB below 1 GHz and ± 2 dB up to 18 GHz. Built into a compact stalk-style housing, the EMSense Platinum contains three orthogonal dipole antennas and a 1 cm³ measurement volume, making it an ideal choice for both confined and open test environments.

Integration with ETS-Lindgren’s modular EMCenter™ EM8 system is seamless, offering flexible configurations ranging from single-slot benchtop units to high-speed, multi-slot rackmount systems.

To maintain its measurement integrity over time, the probe is factory-calibrated in accordance with ISO/IEC 17025 standards, with all adjustment parameters—such as temperature compensation and linearity—stored internally. Additionally, users can upload custom frequency correction data for each axis directly into the probe memory, eliminating the need for manual software adjustments and enhancing usability across multiple setups.
