radio spectrum analyzer

基本解释

Because traditional radio monitoring system is composed of a spectrum analyzer and a single or a multi channel receiver, system performance and automation has been restricted greatly.
傳統的監測系統採用單信道或多信道數字監測接收機和頻譜分析儀搆成，系統性能和自動化程度受到較大限制。
Spectrum of the amplitude-modulated wave is observed by a radio frequency spectrum analyzer and amplitude values of every spectrum are recorded at the upper sideband or lower sideband.
用射頻頻譜分析儀觀測一個已調波的頻譜成分，記錄上邊帶或下邊帶中各條譜線的幅度值，從而可以根據有關算式計算出調制信號（音頻信號）的失真度。
