eoSense Opto-electronic Converter

Functionality

The system allows for the measurement of the E-field VECTOR (amplitude and phase for each eigen axis). The E-field measurement is totally independent from the B-field. The electro-optic probes technology allows the best possible measuring performances without disturbing the E-field.

The eoSense converter provides, per channel:

  • A fully analogue signal (VOUT) proportional to the E-field component to be measured. This signal is recorded and stored either by any oscilloscope (for time domain analysis) or by a spectrum analyser or a VNA (for frequency domain analysis).
  • The Normalisation Factor (analogue value delivered by the OE converter) or the Antenna Factor (digital value read on the PC) lead to the absolute value of the E-field signal in V/m.

This opto-electronic converter must be used with the eoProbe sensors, a dedicated Kapteos software or dedicated instructions sent from your own software via the Ethernet port. It operates up to three directly connected eoProbes .

In real-time, the (100% analog conversion) the optical signal transmitted by the eoProbe is converted into an electrical signal that can be analysed with an instrument like an oscilloscope, a spectrum analyser. It includes an antenna factor (AF) real-time treatment for measuring absolute electric fields (modulus, phase). Each eoSense is delivered with a Routine Test Report valid for 2 years.
