about dbm/200khz problem..

lalajie

Dear all :
               The doc spec write as below ,
                   Frequency         Emission 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=200khz  and measured spurious below -30dbm is pass ?
                   or others )

              Thanks.

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.
