NEXT MIN
RIGHT
The NEXT MIN RIGHT softkey sets the active marker/delta marker to the
next higher minimum right of the current marker position on the selected tra-
ce.
IEC/IEEE-bus commands: CALC:MARK:MIN:RIGH
CALC:DELT:MIN:RIGH
NEXT MIN
LEFT
The NEXT MIN LEFT softkey sets the active marker/delta marker to the next
higher minimum left of the current marker position on the selected trace.
IEC/IEEE-bus commands: CALC:MARK:MIN:LEFT
CALC:DELT:MIN:LEFT
PEAK
EXCURSION
The PEAK EXCURSION softkey enables – for level measurements – the
entry of a minimum level value by which a signal must rise or fall so that it will
be identified as a maximum or a minimum by the NEXT PEAK and NEXT
MIN search functions.
Valid entries are from 0 dB to 80 dB; the resolution is 0.1 dB.
IEC/IEEE-bus command: CALC:MARK:PEXC 10dB
The default setting for the peak excursion is 6 dB. This value is sufficient for
the NEXT PEAK and NEXT MIN functions if NEXT MODE ABS is selected
since, in this mode, the next lower maximum or next higher minimum will al-
ways be detected.
If SEARCH NEXT LEFT or SEARCH NEXT RIGHT is selected, the NEXT
PEAK and NEXT MIN functions search for the next relative maximum or mi-
nimum right or left of the current marker position irrespective of the current
signal amplitude. Relative maximum is understood to mean a decrease of the
signal amplitude by a defined value – i.e. the peak excursion – right and left of
the amplitude peak.
The 6 dB level change set as a default value may be attained already by the
inherent noise of the instrument. In such a case, the R&S ESCI would identify
noise peaks as maxima or minima. The value entered for the PEAK
EXCURSION should therefore be higher than the difference between the hig-
hest and the lowest value measured for the displayed inherent noise.
The following example illustrates the effect of different settings of the PEAK
EXCURSION.
