Hi friends,
We meet one case about avarage usable sensitivity issue.Our unit(walkie talkie PMR446MHz) conduct
measure sensitivity is -121dBm@12dB,and outdoor field test range is 3.2Km in all directions(8 directions,45 degree/direction),but when we sent to lab for test,the result(radiation measurement) fail.we have ever suspected our unit cause the problem,but outdoor test range is good(23dBm TX power&-121dBm sensitivity).
Anyone can guide me what is going on the test result and how to measure so weak signal with radiation measurement correctly?Attach my unit antenna measure data and standard about avarage usable sensitivit radiation measurement----clause 8
Thank you
