PROBLEM TO BE SOLVED: To provide a signal receiving/analyzing device which can reduce degradation of signal quality due to noise in a device which transmits a signal subjected to frequency conversion and composition for each channel by a signal reception unit to a signal analysis unit on one transmission line, and analyzes the signal by the signal analysis unit by performing frequency conversion again for each channel.SOLUTION: A signal analysis unit 2 outputs a reference signal generated from a reference signal generation unit 26 to a frequency divider 29 provided for each channel and transmits the reference signal to a signal reception unit 1. The signal reception unit 1 receives the reference signal and distributes the reference signal to a frequency divider 17 provided for each channel. Each frequency divider 17 and each frequency divider 29 divide the frequency of the reference signal by a frequency division value preset for each channel. The divided frequency is used by the signal reception unit 1 of a signal receiving/analyzing device in the first frequency conversion for converting to a different frequency for each channel, and by a signal analysis unit 2 in the second frequency conversion for returning the converted frequency to the original frequency.COPYRIGHT: (C)2012,JPO&INPIT【課題】 信号受信部でチャネル毎に周波数変換され合成された信号を1本の伝送路で信号解析部に送信し、信号解析部でチャネル毎に再度周波数変換して解析する装置において、雑音による信号品質劣化を低減できる信号受信解析装置を提供する。【解決手段】 信号解析部2が、基準信号生成部26で生成された基準信号を、チャネル毎に設けられた分周器29に出力すると共に信号受信部1に伝送し、信号受信部1が、基準信号を受信してチャネル毎に設けられた分周器17に分配し、各分周器17及び各分周器29が、予めチャネルに応じて設定された分周値で基準信号をそれぞれ分周し、分周された周波数を、信号受信部1でチャネル毎に異なる周波数に変換する第1の周波数変換と、信号解析部2で変換された周波数を元に戻す第2の周波数変換で用いる信号受信解析装置としている。【選択図】 図1
