5.4.1.2 Rules for Ripple Test Definition
The analyzer places few restrictions on the definition of ripple limit ranges.
The following rules ensure a maximum of flexibility:
●
Ranges do not have to be sorted in ascending or descending order (e.g. the "Start
Stimulus" value of range no. n does not have to be smaller than the "Start Stimu-
lus" value of range no. n+1).
●
Overlapping ranges are allowed. The limit check in the overlapping area is related
to the tighter limit (the pass test involves a logical AND operation).
●
Gaps between ranges are allowed and equivalent to switching off an intermediate
ripple limit range.
●
Ripple limit ranges can be partially or entirely outside the sweep range, however,
the limits are only checked at the measurement points.
The following figure shows a ripple limit test involving 3 active ranges.
