frequency in Index 4567. The center frequencies are set to the frequencies at which
peaks are currently observed. The frequency range without exceeding the limit value is
thus defined by the current fre/- the tolerance.
Once the peak frequency ranges are defined, the minimum and maximum amplitude
values of all defined peaks can be read out. These can be used to get a better
impression of the range of values of the amplitudes. Likewise, the maximum amplitude
values in the frequency ranges between the defined peak frequency ranges, before the
first peak frequency range and after the last peak frequency range can be output.

An upper and lower limit value for the amplitude can be set for each defined peak
frequency range. The special feature of the standard analysis is that upper limit values
can also be set for the areas between the peaks via Index 4572.
NOTE
In the case of broadly tapering peaks, it can be difficult to simultaneously define a
sufficiently narrow frequency range for the peak and still obtain reasonable maximum
amplitude values for the ranges between the peaks.
In the case of broadly tapering peaks, the entire peak is often not within the peak fre‐
quency range. This may result in the maximum amplitudes in the intermediate ranges
being defined by the offshoots of the peak, as illustrated in
. A frequency
range before and after the peak frequency range can therefore be defined in Index
4568 and 4569; this range will be ignored. In this way, it can be ensured that the
broadly tapered peak does not affect the amplitudes in the intermediate ranges before
and after the peak.
