Comparing Traces/Performing Data Math

Each of the traces for which measured data is displayed is provided with an additional
trace, called a memory trace, that temporarily stores measured data. You can use the
memory trace to compare traces on the screen or to perform complex data math between
the memory trace and measured data.
The following data math operations are available:
Data / Memory
Data * Memory
Data − Memory
Data + Memory

Comparing Traces/Performing Data Math
Divides the measured data by the data in the memory trace. This
function can be used to evaluate the ratio of two traces (e.g., evaluating
gain or attenuation).
Multiplies the measured data by a memory trace.
Subtracts a memory trace from the measured data. This function can be
used, for example, to subtract a vector error that has been measured and
stored (e.g., directivity) from data subsequently measured on a device.
Adds the measured data and the data in the memory trace.
