Fig. 4-13 Examples of level measurement with different settings of PEAK
EXCURSION
Maximum relative level change between the measured signals:
Signal 1 to signal 2: 30 dB
Signal 1 to signal 3: 55 dB
Signal 1 to signal 4: 56 dB
With 40 dB peak excursion, signal 3 will be detected by NEXT PEAK and
signal 4 by NEXT PEAK RIGHT. Signal 2, by contrast, will not be detected be-
cause the signal level decreases by only 30 dB between signal 1 and signal 2.
Signal 4 will not be detected with NEXT PEAK, as the signal level decreases
by less than 40 dB between signal 3 and 4.
Order of signals detected:
PEAK: signal 1
NEXT PEAK: signal 3
NEXT PEAK: no further signal detected
or
PEAK: signal 1
NEXT PEAK RIGHT: signal 4
NEXT PEAK RIGHT: no further signal detected
With 20 dB peak excursion, signal 2 will also be detected since the largest
signal level change of 30 dB between signal 1 and 2 is now greater than the
peak excursion.
Order of signals detected:
PEAK: signal 1
NEXT PEAK: signal 2
NEXT PEAK: signal 3
NEXT PEAK: no further signal detected
