1. It means when I measure use Spectrum Analyser I need to set 8 K l5 ^6 C' h' w
RBW=200Khz start=2Mhz stop=50Mhz,
$ u, ~0 F9 L3 b: x9 |! {8 |' t if measured power level >-30dBm then it's fail , <-30dBm it's pass.
7 v: s4 ?. ~5 g6 ^3 t. c, n# {6 r Right ?- a% A5 z, ^3 ~+ e6 M
! s( l% }1 O6 I7 @5 ^" ]7 w$ k* D0 K
2. But my boss tell me it's need below -70dbm not -30dbm , I don't know why.
' Z8 V4 d# o, \ If I transfer it to dbm/hz is -83dmb/hz ,it become more severe than -70dbm
. Z' E5 } S/ W# x+ X2 C M8 O and unit also different.6 C4 k: i6 n, g9 f: C
I don't know which part is wrong ?* @$ p9 K5 G# D
