Hi Stefan,

>> I measured 6,56Np over 1mW which should do for a start.

  >Wuuw, Np! So P= 1 mW * 2.718 EXP(6.56) = 706 mW ??

Try  ln [SQRT (P/0,001W) ] = 6,56Np

Solve for P which is a bit tedious and you end up with
P= e^(2*6,56+ln 0,001)

Or you convert Np directly into dB which is much simpler (1Np = 8,686dB) ...
