Electric Field Probe

For field strength / field homogeneity measurements during radiated immunity tests acc. to. IEC/EN 61000-4-3

DESCRIPTION:
The LUMILOOP Electric Field Probe type LSProbe 1.2 especially has been designed for field strength measurements / field
homogeneity measurements during radiated immunity tests according to IEC/EN 61000-4-3. However, it is also excellent to
measure the radiation pollution of the environment, for example at workplaces or flats.

The LSProbe 1.2 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 even does not need any metering unit (which could also influence the field-strength), because of its direct fibre-optic output, which does allow direct connection of the sensor to the USB-interface of the control PC or laptop. The measuring values may be displayed via the individual IEC 61000-4-3 control software or via a windows-software included in the delivery

The LSProbe 1.2 cover the frequency-range from (10 Hz) 10 kHz – 8.2 (12) GHz. The utilized linearization technology provides a dynamic range up to 100 dB. The LSProbe 1.2 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 measurments down to 0.1 V/m. The probe is laser-powered to allow continuous, galvanically isolated operation without recharging or battery replacement The power supply unit comes in a small handy box.
