FR4003 – Field Receiver
Description
The FR4003 is the new gold standard in measuring electric fields up to 30 MHz. Thanks to its innovative approach it replaces traditional rod antennas and adds several benefits. It fully meets all MIL-STD and CISPR specifications for rod antennas and is also a fully-compliant CISPR 16-1-1 receiver with a fiber optic link that allows it to work as a stand-alone device (when connected to a PC) or in tandem with a PMM receiver. It fully meets all the standards in both swept and FFT mode, as selected by the user.
It is possible to switch the analog signal from the internal receiver to the analog output and connect it to any standard receiver by traditional coaxial cable, although this is not recommended due to scattering and other drawbacks typical of rod antennas.
The internal receiver structure features pre-selectors, attenuators and preamplifiers fully controlled either by the internal firmware or manually by the operator. Hence, a test set-up requires no additional receiver. An internal tracking generator allows a self-calibration procedure to guarantee optimum performance and accurate measurements. This tracking generator is part of an internal capacitance meter that is crucial not only for self-calibration, but also for verifying the grounding effectiveness of the antenna. The FR4003 can even become a field generator. In this case the antenna broadcasts the signal produced by the internal signal generator and can therefore be used to characterize environments or other receiving set-ups.
Standard PEMS controlling software is included with the FR4003. Thanks to its rechargeable and easily replaceable Li-ion battery, the FR4003 can work for several hours on its own and therefore with an unperturbed field.
