Jan de Vries:
So i cannot do the meassurments conform ITU-R SM.1268-1, although you have the mask drawn in the spectrum analyser, and the mask on the  analyser is there but not related to anny meassuring methode.
Am reading your comments right ??

Jan:
It is already mentioned in the manual: "If the spectrum plot is outside the mask on any frequency, the transmission device may be considered as overmodulating. If the spectrum plot is within the mask, additional peak frequency deviation measurement must be always made to verify if the station exceeds the peak deviation limit or not."
In other words, exceeding the mask limit gives a final information that the transmitter does not pass the test. A curve that is entirely below the limit does not bring any information (in relation to ITU-R SM.1268-1).
