It is happened, despite there is enough reception level (40\uff5e50dB at end terminal), television not can recieve. To measure clearance of dropped ripple is required to solve the problem. <\/p>\n<p> For brief sequence of measurement, Use the full span function in this spectrum analyzer. Indicate wide band spectrum. Narrow down the span. Detect a point of dropped noise. Moreover narrow down the span until the dropped noise is visible in this analyzer screen. <\/p>\n<p> This analyzer is helpful for checking phenomenon of multipath and distortion by booster interference. <\/p>\n\n\n\n<h2>Solution<\/h2>\n<h3>Connection image<\/h3>\n<img loading=\"lazy\" decoding=\"async\" src=\"\/eng\/image\/application\/DTB-00.jpg\" alt=\"Figure:Connection image\"
