1. It means when I measure use Spectrum Analyser I need to set 1 h& ]! T+ @# Z4 x( ]
RBW=200Khz start=2Mhz stop=50Mhz,8 }- x- y6 v; g" v
if measured power level >-30dBm then it's fail , <-30dBm it's pass., R8 j! h* y; u( [5 t
Right ?, _- q0 B7 j' o( P% ~8 i+ d4 H2 C

2. But my boss tell me it's need below -70dbm not -30dbm , I don't know why.& N( Z8 c q' V& _
If I transfer it to dbm/hz is -83dmb/hz ,it become more severe than -70dbm R0 B9 y6 E }* z3 Q' E. E
