偶然发现的，还没搞太明白。
The R&S®PR100系列接收机频率范围为 9kHz to 7.5GHz。配合HE300 系列GPS天线，就可快速检测出干扰手机的干扰源。能扫描很宽的频谱，包括GSM、UMTS，CDMA2000和LTE网络，协助消除干扰源。
此接收机提供10MHz实时中频频谱，可在150Hz~500KHz宽范围内解调。
此便携式接收机提供艺术级的数字信号处理，提供高灵敏度的接收，确保检测极弱信号又不降低处理速度。
我的看法是，这个是手持扫频仪，接收信号后，进行数字中频信号处理及解调，也就是说它是一个非常宽频的接收机，能接收从9KHz到、长波、中波、短波、调频广播、电视、对讲机、手机信号、卫星信号，还能形成频谱并解调出来。有了此物，不需别的任何接收机了。别说HAM们津津乐道的偷听二奶台了，如果知道通信密码，任何手机通话都能听到。
不知有谁试过没有，看了此机后觉得虽然改革开放三十年了，国内电子从业人员不知在干些啥。业余爱好者限于条件，但那些技术人员和厂家还继续不思进取一心用那一点点知识和粗糙产品在骗钱？
The R&S®PR100 Series portable receiver operates in a wide frequency range from 9kHz to 7.5GHz, and when combined with the R&S®HE300 Series GPS enabled directional antenna, is ideal for quickly detecting and locating the source of cellular band interference disrupting wireless infrastructure equipment.
Featuring a compact and lightweight design, the reliable R&S®PR100 portable receiver provides 10MHz real-time IF spectrum and demodulation over a bandwidth ranging from 150Hz to 500kHz.
The R&S®PR100 portable receiver scans a broad frequency spectrum, including GSM, UMTS, CDMA2000® and LTE networks to quickly detect and assist in eliminating the source of interference. The R&S®PR100
portable receiver features state-of-the-art digital signal processing that provides high receiver sensitivity to enable detection of extremely weak signals without loss in processing speed.
