Narda Safety Test Solutions PMM 9180 EMI receiver unit

Narda Safety Test Solutions has released the EMI receiver unit PMM 9180 which extends the frequency range of the digital EMI receiver PMM 9010 up to 18 GHz for measurements of EMC emissions in full compliance to CISPR and MIL-STD standards.

The receiver features modularity that allows the main unit (10 Hz - 30 MHz) to be extended in frequency to 3 GHz (PMM 9030), 6 GHz (PMM9060) and to 18 GHz with the recently released model PMM 9180 by simply adding one of these external modules.

All these modules are EMI receivers, fully compliant to CISPR and MIL-STD standards. Small-sized and lightweight, these modules can be easily installed inside the anechoic or shielded chamber, directly connected to the measuring antenna and fixed to the mast by means of an adapter. The connection with the main unit PMM 9010 - which remains in the instruments room - is made by high-speed digital link via fibre-optic cable. Up to four hours of continuous in-room operation are provided by the plug-in, rechargeable Li-ion battery.

Additional features include: elimination of signal loss due to the coaxial cable and to the connections; improvement of the receiver dynamic range without needing preamplifiers; improvement of the overall uncertainty; elimination of interfering signals that may be picked up along the coaxial cable path; elimination of scattering phenomena due to the coaxial cable; calibrations of the coaxial cables are not needed; in comparison with the coaxial cables, the unpaired flexibility of fibre-optic allows for easier installation even in the same path of power cables and reaches long distances (up to 100 m).

The PMM Emission Suite software is supplied with the receiver and allows for complete control of the tests, including mast and turntable functions.
