When internet line is unconnect by up stream noise, in order to solve the problem, It is not enough measureing peak level of  the noise by spectrum analyzer. It is necessary to measure carrier to noise ratio (C\/N). And compare carrer signal to figure noise. Our spectrum analyzer is handy, and lightweight,battery drive. It is useful when you acquire data in field survey, This analyzer directly can save a data (CSV format) in a USB mem ory. It is easy to read out data and quickly monitoring spectrum  wave data and setting paramete on analyzer's screen. Moerever the price is very reasonable. Consequently it can to curb installation cost. <\/p>\n\n\n\n<h2>Solution<\/h2>\n<p class=\"miniTitle\" style=\"text-align:left;padding-left:1em\">1.Up stream noise measurement of CATV<\/p>\n<ul
