Vector E-Field Probes
Kapteos eoProbe Kapteos Logo  Made in France

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

Comprehensive non-invasive electric field measurement system.

No metal content E-Field probe 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

triaxial: optic probe (1 probe measures 3 axis of an electric field)

Kapteos E-Field Vector Probe System 

Kapteos new triaxial vector electric field probe

How to measure the three components of the E-field vector within a small enclosure?

For that purpose, Kapteos introduces a breakthrough with a triaxial vector electric field probe. Such probe allows to measure sequentially the three E-field components while staying in same position and direction. To switch from Ex to Ey component, and then from Ey to Ez component, the probe simply needs to be rotated 120°

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.
