RBW=200Khz start=2Mhz stop=50Mhz,% a9 W5 B# G. J5 d8 @ h. C
if measured power level >-30dBm then it's fail , <-30dBm it's pass.$ z, a+ }, O p2 W7 r3 ] `$ L
Right ?2 Y1 E2 B6 I" k: u; g

2. But my boss tell me it's need below -70dbm not -30dbm , I don't know why.# r8 b- r/ B0 x A- D
If I transfer it to dbm/hz is -83dmb/hz ,it become more severe than -70dbm
% X0 y, g' z! t/ O and unit also different.
