about dbm/200khz problem..

Dear all :
2 m# o+ v9 R  X7 Y               The doc spec write as below ,
                   Frequency         Emission Level
) s( Q8 ~5 y6 g                2Mhz to 50Mhz    -30dbm/200khz
; d3 p2 l% e( @+ a' V- d! A$ A8 X; ]
             1. what's it mean ?
             2. How should I do when I measure spurious use Spectrum Analyzer ?
& w: t4 @* a: W8 p+ \& ~7 w$ G            (ex: set RBW=200khz  and measured spurious below -30dbm is pass ?
                   or others )
0 ^) \6 q1 m* q- M# Q
8 h; T+ v, w1 Z. h$ x# e' l
              Thanks.

I'm not an expert, I think "set RBW=200khz  and measured spurious below -30dbm is pass" is correct.
I 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
              RBW=200Khz start=2Mhz stop=50Mhz,
             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.
( W% n+ n: S- q4 B9 X             I don't know which part is wrong ?
