7.10.3 Trace Math
Access : TRACE > "Trace Math"
If you have several traces with different modes, for example an average trace and a
maximum trace, it may be of interest to compare the results of both traces. In this
example, you could analyze the maximum difference between the average and maxi-
mum values. To analyze the span of result values, you could subtract the minimum
trace from the maximum trace. For such tasks, the results from several traces can be
combined using mathematical functions.

Trace Math Function
Defines which trace is subtracted from trace 1. The result is displayed in trace 1 and
refers to the zero point defined with the
Trace Math Position setting. The following sub-
tractions can be performed:
"T1-T2->T1" Subtracts trace 2 from trace 1.
"T1-T3->T1" Subtracts trace 3 from trace 1
"T1-T4->T1" Subtracts trace 4 from trace 1
"T1-T5->T1" Subtracts trace 5 from trace 1
"T1-T6->T1" Subtracts trace 6 from trace 1
To switch off the trace math, use the Trace Math Off button.
