about dbm/200khz problem..

super

Dear all :
               The doc spec write as below ,
                   Frequency         Emission Level
                2Mhz to 50Mhz    -30dbm/200khz

0 Z( D+ M; ], r1 _4 A; k) f             1. what's it mean ?
  D- }9 B. x) ~4 T. h             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.

I'm not an expert, I think "set RBW=200khz  and measured spurious below -30dbm is pass" is correct.
. c# f$ f6 \; s2 N" V# a& j- g" rI know another spec: -40dBm/1MHz, that's to measure dBm per 100k(RBW=100k)., then sum(10), if below -40dBm is pass.

Dear sir :
           Thanks your reply.
            To confirm again ,
          1. It means when I measure use Spectrum Analyser I need to set
5 l* g/ f5 |1 t& x1 s              RBW=200Khz start=2Mhz stop=50Mhz,
             if measured power level >-30dBm then it's fail , <-30dBm it's pass.
/ U9 f( c& \# C' m* m              Right ?
2 m. G9 L% `# |+ g  r/ p8 t
4 t  C$ A: A/ j8 U# k6 k" V          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 ?
