To confirm again ,

RBW=200Khz start=2Mhz stop=50Mhz,; M$ ]" t5 {2 L0 z9 ]: S
if measured power level >-30dBm then it's fail , <-30dBm it's pass.
9 z* s+ k* v+ s3 A Right ?
3 x- g# B7 [( c+ P* v
: |5 |& P* d2 B) ?1 u, F5 D& u- Y$ { 2. But my boss tell me it's need below -70dbm not -30dbm , I don't know why.# l3 p/ X: x* e+ u* N
If I transfer it to dbm/hz is -83dmb/hz ,it become more severe than -70dbm
5 n8 _5 ]# d3 j7 F9 f0 m and unit also different.
