Compatibility between traces in mathematical relations
Mathematical traces are either constant functions or functions of one or more data or
memory traces. They are calculated on a point-to-point basis. Each trace point no. i of
the mathematical trace is calculated from a set of constant values c
1
, ..., c
n
plus the
trace points Trc1
i
, Trcm
i
of all traces 1 to m in the mathematical relation:
Math
i
= Fct. (c

, ..., c
n
, Trc1

, Trcm
i
), i = 1, no. of points
Different traces can be used in the same mathematical relation provided that they con-
tain the same number of points. The analyzer places no further restriction on the com-
patibility of traces, e.g. the sweep points of the traces do not have to be the same.
The number of points belongs to the channel settings. Coupled data and memory
traces are always compatible because they have the same channel settings.
The analyzer processes only numeric values without units in the mathematical formu-
las. No consistency check for units is performed.
