Kapteos Vector Electric Field Probes (40Hz to 100GHz)

Comprehensive electric field measurement system

The picture below presents the up to date available products and accessories.
The minimum required system to perform an electric field measurement is to have the eoProbe sensor connected to the optoelectronic converter called eoSense.

 

 

The System Components are as follows:

  • eoSense: opto-electronic converter (from 1 to 3 channels)
  • eoProbe: optic probe (1 probe measures 1 axis of an electric field)
  • eoSwitch: optical switch to select a probe among several ones
  • eolink: optical extension lead
  • eoCal: electric field applicator to calibrate a probe
  • eoPod: holder to maintain up to 3 probes

Data
This opto-electronic converter must be used with the eoProbe sensors, a dedicated Kapteos software or using dedicated instructions sent from your own software via the Ethernet port. It operates up to 3 eoProbe directly connected. It converts in real-time (100% analog conversion) the optical signal transmitted by the eoProbe into an electrical signal that can be analysed with an instrument like an oscilloscope, a spectrum analyser or any other signal processing instrument.
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.
