Laser Powered E-Field Probe


Lumiloop LS 1.2 Probe


Frequency Ranges:
Standard: 10 kHz ... 6 GHz
Option LO: 10 Hz ... 6 GHz
Option HI: 10 kHz ... 8.2 GHz
Option HI+LO: 10 Hz ... 8.2 GHz

Best-in-class compensation of linearity, frequency and temperature guarantees accurate measurements from less than 0.1 to at least 1,000V/m.

A dynamic range of 100 dB is achieved for many frequencies, enabling field measurements at more than 10,000V/m
Customization for higher field strenth on request.




User Manual


The miniaturized 6 GHz 3D E-Field Analyzer LSProbe ensures unattended, uninterrupted measurements combined with high resolution, high speed and low noise over the entire test period.

With the galvanically insulated power supply, the need for batteries is now eliminated.

The field probe does not only measure average values but the time course of fields. With an unprecedented wide dynamic range and fast pulse response, LSProbe provides the user completely new measuring options.

The LSProbe enables a higher efficiency through shorter and lower-cost testing intervals.
