Each of the traces for which the 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 |
|
Data / Memory |
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). |
|
Data * Memory |
Multiplies the measured data by a memory trace. |
|
Data - Memory |
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 the data that is subsequently measured on a device. |
|
Data + Memory |
Adds the measured data and the data in the memory trace. |
