eoSense converter: to operate the probes that measure the E-field (EMF)

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 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.

Above 40 GHz, systems are based on requirement.

Main advantages

Automatic antenna factor correction

Real-antenna factor correction

This unique feature takes into account the full measurement channel to minimize the errors like temperature drift, vibrations, fibre optic. This feature allows to reach very high performances.

Basic frequency curve

Fully calibrated for better performances

Each system delivered by Kapteos is calibrated for a period valid for 2 years. A calibration certificate is provided in standard. This feature allows to reach very high performances.

Easy operation of electric field measurement system

Easy operation

Less than few minutes is needed to start an electric field measurement thanks to the user-friendly software, opto-electronic converter and wide choice of accessories.

100 meters of optic fibre

Up to 100 meters of fibre optic

Thanks to Kapteos technology, up to 100 meters of fibre optic may be used between the measured E-field and the converter. More than enough!

Options for the eoSense opto-electronic converters

Amplification option inside instrument

Internal amplification of signal : AMP

Depending of your need, Kapteos may propose you to integrate an internal amplifier to reach your required specifications of low E-field values.

Accessories for the eoSense opto-electronic converters

eoLink fibre optic extension

Fibre optic extension

The fibre optic extension is inserted between the eoSense converter and an eoProbe sensor to increase the distance up to a maximum of 100 meters. A rugged version for outdoor usage is available in standard.
