Overview
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:
Value Description
Divides the measured data by the data in the memory trace.
Data /
This function can be used to evaluate the ratio of two traces
Memory
(e.g., evaluating gain or attenuation).
Multiplies the measured data by a memory trace.
Data *
Memory
Subtracts a memory trace from the measured data. This
Data -
function can be used, for example, to subtract a vector error
Memory
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.
Data +
