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 it
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 later data measured on a
device.
Adds the measured data and the data in the memory trace.

Function
Turns off data math functions (Do not perform
data math.).
Divide the measured data by the memory trace
and store the result in the data trace.
Multiply the data trace by the memory trace
and store the result in the data trace.
Subtract the memory trace from the data trace
and store the result in the data trace.
Add the data trace and memory trace and store
the result in the data trace.
