Module triples digital emc testing range

The PMM 9180 is designed for commercial test labs, in house manufacturers' test facilities and a wide range of emc testing. According to Teseq, it offers high performance and cost savings by cutting turnaround times and eliminating the need for expensive coax cables and periodic calibration checks. And, says Teseq, it provides better radiated emissions system sensitivity than other units on the market. The battery powered PMM 9180 is said to be the only fully compliant emi receiver module on the market directly connected to an antenna located inside the testing chamber. Teseq notes that it has the ability to transmit data outside the testing chamber via fibre optic cable, eliminating signal losses that can exceed 20dB. The device is fully compatible with CISPR 16-1-1 and MIL-STD and 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 1.8GHz as well as MIL 461 RE 102 testing, which has an upper frequency limit of 18GHz. It can also be used for CE marking. The PMM 9180 is compatible with the PMM Emissions Suite software, which offers full control of auto and manual receiver functions, real time display, editing of standard limits, creation of correction factors tables and warning messages for incorrect settings. The software includes one click operation for selecting measuring mode: swept, spectrum analyser or tuned. All measurements taken by the receiver can be retrieved, saved, recalled and compared when using PMM's PC Emissions Suite software. According to Teseq, the PMM 9180 features a high speed optical interface, an operating temperature of 5 to 45°C, a measurement accuracy of 2dB and a maximum input level of 137dBuV without damage.
