The PMM Narda FR4003 Field Receiver , is a new reference in measuring electric fields up to 30 MHz.
Thanks to its innovative approach, it replaces traditional rod antennas adding several benefits. It fully meets all military standards and, CISPR specifications, of the rod antenna, and it is a real full compliant CISPR 16-1-1 receiver with the capability of working, via fibre optic link, either stand alone when connected to a PC, or connected to a PMM receiver. Nonetheless, it can maintain full legacy with any standard receiver, because it also has the traditional coaxial cable output.
The internal receiver structure, features preselectors, attenuators and preamplifiers, fully controlled either by the internal firmware, or manually, by the operator. Hence, a test set-up does not need any additional receiver. Moreover, an internal tracking generator, allows performing a self-calibration procedure which always guarantees optimum performances, ensuring the accuracy of measurements. The same internal tracking generator, is part of an internal capacitance, meter, that becomes essential, not only for the self-calibration, but also for verifying the grounding effectiveness of the antenna.
Last but not least, the FR4003 can become a field generator. In this case, the antenna broadcasts the signal, made by the internal signal generator, and can thus be used to characterize environments or other receiving set-ups.
In addition to the PMM Emission Suite, the FR4003 comes also with a controlling software, which can be used when connected to a standard receiver. Thanks to its replaceable Li-Ion battery, the FR4003 can work for several hours, with no connection, having thus unperturbed field.
