楼上说的接收机的频谱是指扫描时候的解析带宽RBW吗,如果是重要,那EUT的电磁干扰的带宽是指那个,是否指的是FCC中的那个6dB的带宽?
我看了标准上有这么一句:narrowband: equipment to be used in a non-channelized continuous frequency band of equal or less than 200 kHz, or equipment to be used in a channelized frequency band with a channel spacing of equal or less than 200 kHz
wideband:equipment to be used in a non-channelized continuous frequency band covering more than 200 kHz, or equipment to be used in a channelized frequency band with a channel spacing greater than 200 kHz。
我想知道这个200K赫兹是指什么带宽? |
