Specification: , detection frequency range: 9khz~30mhz (kh3961) or 9khz~300mhz (kh3962) , frequency stability: 1x 10-6 , frequency resolution: (9khz~150khz) 30hz; (150khz~30mhz) 1khz , test tolerance: ¡¨¤2 db , measure and detection method: pk, qp and av , measure range from 20db|¨¬v to 140db|¨¬v , frequency scanning step length: 20hz~2mhz , sweep bandwidth: 200hz; 9khz; 120khz , connect pc via usb and software can be run win7, win8 Kh3962 is an automatic emi receiver system. It is a main test system for emi (electro magnetic interference) testing. The kh3962 is produced by the full closure structure and strong electro-conductibility material, which has high shielding effect. Due to the new technology for the emi test system, it solved the instrument self-emi problem. The test results are according to the international format test report. The emi test system kh3962 fully meets cisprl6-1, gb17743, fcc, en55015 and en55022.
