TES3000 is an isotropic, selective, electric field probe operating on a very broadband frequency range: from 100 KHz to 3 GHz. The wide frequency range covers many applications, from AM to FM radio, analog and digital TV, all mobile phone bands, including UMTS, Bluetooth.
Originally designed for military applications (NEMP), after the implementation of a few simplifications, it has been optimised for the measurement of the electric field generated by RF transmitters as a human safety related instrument. The most recent developments, funded by the Italian National Research Council, have recorded the embedding of the fiber optic probe in selective narrowband peripheral stations forming a wireless automatic field monitoring network covering large highly populated areas.
The main use is therefore expected to coincide with the measurement of the electric field radiated by telecommunication antennas, the so called “electrosmog”. The TES3000 is able to give the total field without any mechanically rotating element at selected frequencies, irrespective of the field polarization and direction of propagation, in near and far field conditions, even close to metallic structures.
It can however be utilized, thanks to its small size, to map narrow cavities, like, for instance, to measure the shield effectiveness of small Faraday cages and electronic equipment cabinets.
TES1000 is the first of a family of selective probes that in association with a spectrum analizer and, optionally WIN-MF software allow the acquisition of electric field levels over broad frequency ranges with discrimination of the sources.
TES1000 operates from 100 KHz to 1 GHz with linearity guaranteed up to 30 V/M. Different ranges can be provided on request. The measurement outdoors proceeds under software control from the acquisition in three orthogonal directions to the identification of major peaks and calculation of total isotropic field. The extreme sensitivity of the probe makes it possible its use in shielding effectiveness tests and mapping of fields inside small shielded enclosures.
