MARGIN The MARGIN softkey activates entry of the margin, i.e. the acceptance threshold for
determining the peak list. The limit line is shifted by this value when the maximums
are determined. The value range extends from -200 dB to 200 dB. The default value
is 6 dB.
Remote command:
CALC:PEAK:MARG –200dB...200dB
VIEW PEAK

peak list.
The header data is made up of three columns, separated by ';':
