kind of Modulation, 一般為FSK).
Tramsmitter
Test Items
1. Emission between 25MHz -1GHz, 3m Test distance
主要Freq. 主頻, Band Edge(26.96MHz and 27.28MHz),諧波, 雜波 , Test Ant. 水平,垂直
Band Edge Limit Mark 26.96MHz and 27.28MHz , Limit 應使用較嚴格限制值(69.5dBuV)
SPA設定 25MHz - 30MHz, RBW, VBW = 10KHz; 30 MHz -1GHz , RBW, VBW = 100KHz
Test Receiver設定 25MHz - 30MHz, RBW, VBW = 9KHz; 30 MHz -1GHz , RBW, VBW = 120KHz
2.Occupied Bandwidth Measurement
測試頻道: Upper and Lower; RBW,VBW min 1KHz, SPAN 50KHz
O.BW 依據ANSI要求-26dB
必須繪圖
