RBW=200Khz start=2Mhz stop=50Mhz,8 X9 Y. @9 x, E# _9 e% D' s7 w' r7 ?
if measured power level >-30dBm then it's fail , <-30dBm it's pass.
: r( ]+ {$ z; u, ?3 ^: K Right ?5 T8 G/ \" x; G4 D, l4 q% ?
) h2 |2 e6 n( K* ?6 n) j. y
2. But my boss tell me it's need below -70dbm not -30dbm , I don't know why.( Q6 t2 ?5 j# Y2 z4 g6 e/ T
If I transfer it to dbm/hz is -83dmb/hz ,it become more severe than -70dbm
