求助:射频电磁场辐射抗扰度问题!----200HMz 無線麥克風
在測試
垂直极化: 80-100M, SINAD: 9dB;
300-320M, SINAD: 4dB;
380-400M, SINAD: 3.8dB;
水平极化:120-125M, SINAD: 4dB;
本產品需要過EN300489-01:V1.8.1 標准. RS
產品為接收模組, 四周都被鐵外殼包住. 只有供電電源線和天線,信號線外引出來.
the test level shall be 3 V/m (measured unmodulated). The test signal shall be amplitude modulated to a depth of 80 % by a sinusoidal audio signal of 1 000 Hz. If the wanted signal is modulated at 1 000 Hz, then an audio signal of 400 Hz shall be used;
the test shall be performed over the frequency range 80 MHz to 1 000 MHz and 1 400 MHz to 2 700 MHz with the exception of the exclusion band for transmitters, receivers and duplex transceivers (see clause 4), as appropriate;
for receivers and transmitters the stepped frequency increments shall be 1 % frequency increment of the momentary used frequency, unless specified otherwise in the part of EN 301 489 series [11] dealing with the relevant type of radio equipment |
