about dbm/200khz problem..

Dear all :
               The doc spec write as below ,
" ]1 P4 \0 H' K, q4 X8 X                   Frequency         Emission Level
                2Mhz to 50Mhz    -30dbm/200khz
( `: E% E9 k! Y9 j4 f
( I6 d0 b# }3 Z3 ], ]             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 ?

I'm not an expert, I think "set RBW=200khz  and measured spurious below -30dbm is pass" is correct.
9 k. n9 h' u7 }; r2 B. eI know another spec: -40dBm/1MHz, that's to measure dBm per 100k(RBW=100k)., then sum(10), if below -40dBm is pass.

Dear sir :
- N, P  e6 G4 S4 k           Thanks your reply.
            To confirm again ,
+ b' {2 M4 t- g1 r2 `7 P  Q          1. It means when I measure use Spectrum Analyser I need to set
              RBW=200Khz start=2Mhz stop=50Mhz,
             if measured power level >-30dBm then it's fail , <-30dBm it's pass.
3 i& r! v4 o% ^( M2 j8 _7 A              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
- {% k" o4 Q0 H! w             and unit also different.
7 s! v; }  i# M: K% s             I don't know which part is wrong ?
