Test Equipment Description

The all-in-one that sets the standard for miniature optically coupled broadband E-field isotropic probes. Exceptionally small-sized spherical symmetrical configuration, lightweight and miniaturized electronics combined with excellent RF characteristics make the Narda PMM EP-601 isotropic RF electric field probe to 500 V/m is the ideal solution for all EMC/EMI applications (chambers and TEM/GTEM cells), biology and materials research and wherever fast and accurate measurements with negligible or minimum interference of the probe to the field under measure are essential. Accredited calibration on request.

This is a small unobtrusive electric field probe for the measurement of radiated electric field during EN61000-4-3 testing in enclosed chambers or GTEMs. As the immunity specs are now going up to 6GHz the range of this sensor is ideal. It essentially consists of the 'Orthogonal' miniature sensor. The sensor head is then connected via a duplex fibre optic cable interfacing into a fibre to RS232 adapter. A further interface then converts the RS232 to a USB connector. This then connects directly with any laptop with the PMM display software. The hired kit comes with a CD for installing on a customer’s PC. We have also written the driver enabling it to be used with one of our laptops and integrated into our Em-CIM conducted/radiated immunity software package. The probe head itself consists of three miniature dipoles 52mm from end to end. A 10m fibre optic cable will then connect the probe to the RS232 interface module.
