Dear all :
The doc spec write as below ,
FrequencyEmission Level
2Mhz to 50Mhz-30dbm/200khz
1. what's it mean ?
2. How should I do when I measure spurious use Spectrum Analyzer ?
(ex: set RBW=200khzand measured spurious below -30dbm is pass ?
or others )
Thanks.

You got it
Dear sir :
Thanks your reply.
To confirm again ,
1. It means when I measure use Spectrum Analyser I need to set RBW=200Khz start=2.5Mhz stop=100Mhz,
if measured power level >-30dBm then it's fail , <-30dBm it's pass.
Right ?
2. But my boss tell me it's need below -70dbm not -30dbm , I don't know why.
If I transfer it to dbm/hz is -83dmb/hz ,it become more severe than -70dbm and unit also different.
I don't know which part is wrong ?
Thanks.
Sorry , it should be start=2Mhz stop=50Mhz
