1. It means when I measure use Spectrum Analyser I need to set 9 m; d/ M% a) g6 I+ R- _
RBW=200Khz start=2Mhz stop=50Mhz,
7 D5 X8 H# g( v' i" R, F$ D4 y if measured power level >-30dBm then it's fail , <-30dBm it's pass.
) n+ G* g0 p3 ?% y0 N2 ~- v1 e% j Right ?6 {: ]# c+ d7 T' _
- a# w; c6 a$ C T0 c
2. But my boss tell me it's need below -70dbm not -30dbm , I don't know why.
" H) o. ?; j$ Z2 f If I transfer it to dbm/hz is -83dmb/hz ,it become more severe than -70dbm) F9 q6 I- v. T- Q
