Module triples EMC testing range to 18 GHz

A digital EMC/EMI receiver module from TESEQ extends the frequency range of the PMM 9010 receiver system from 6 GHz to 18 GHz.  Suitable for use in commercial test labs and by in-house manufacturers’ test facilities, the upgraded PMM system can now be used for a wider range of EMC testing.

The  PMM 9180 eliminates the need for coax cables and periodic calibration checks and provides improved radiated emissions system sensitivity.

The battery-powered PMM 9180 is an EMI receiver module that directly connects to an antenna located inside the testing chamber and has the ability to transmit data outside the testing chamber via fibre-optic cable, eliminating signal losses that can exceed 20 dB.

The PMM 9180 is fully compliant with CISPR 16-1-1 and MIL-STD.  It features a plug-in Li-Ion rechargeable battery that lasts for a minimum of four hours.

The FCC requires that EMC emissions testing be performed at 10 times the highest clock frequency in a product.  By using the PMM 9180, FCC testing can be performed on products with clock speeds to 1.8 GHz as well as MIL 461 RE 102 testing, which has an upper frequency limit of 18 GHz.  The PMM 9180 can also be used for CE marking.

The PMM 9180 is fully compatible with the PMM Emissions Suite software.  This software offers full control of all auto and manual receiver functions, real-time display, editing of standard limits, creation of correction factors tables and warning messages for incorrect settings.

In addition, the software includes one-click operation for selecting measuring mode: swept, spectrum analyzer or tuned.  All measurements taken by the receiver can be retrieved, saved, recalled and compared when using PMM’s PC Emissions Suite software.

The TESEQ PMM 9180 features an optical interface, an operating temperature of -5°C to 45°C, a measurement accuracy of +2.0 dB and a maximum input level of 137 dBuV without damage.
