 Radiated Immunity RF Field Strength Meters

 

EFS-10 / EFS-100

Frankonia EFS field strength meters have been specially designed for field strength measurements / field homogeneity measurements during radiated immunity tests according to IEC 61000-4-3 & IEC 61000-4-20. The field strength meters can also be used to measure the radiation exposure of the environment at workplaces and other areas of interest. 

The EFS is an isotropic miniature E-field sensor to ensure that the E-field will not be influenced by the size of the sensor itself. It doesn't even need a metering unit (which could also influence the field strength) because of its direct fiber optic output which allows direct connection of the sensor to the USB-interface of the control PC or laptop. The measuring values may be displayed via the individual control software or via a Windows software included in the delivery. 

The EFS-10 & EFS-100 cover the frequency range from 10 kHz up to 9.25 GHz and are able to detect electrical field strength in the range from 0.14 V/m to 500 V/m (depending on type). The sensors are battery operated allowing a maximum operation time of 80 hours before recharging. 

Field strength meters up to 26.5 GHz also available.

EFS-LASER

The EFS-LASER was also specially designed for field strength measurements / field homogeneity measurements during radiated immunity tests according to IEC 61000-4-3. It has the same features as the EFS-10 & EFS-100 but utilizes laser power instead of batteries. This allows continuous, galvanically isolated operation without recharging or battery replacement. The utilized linearization technology provides a dynamic range up to 100 dB. The EFS-LASER is a smart, fast, extremely accurate electric field probe, which provides linearization, temperature compensation, control and communication functions. Noise reduction and temperature compensation allow accurate measurements down to 0.1 V/m.
