All about Trace Math

Trace Math is available ONLY in CAT and NA Modes, but not in DTF
measurements.
A trace is a series of measurement data points that are connected to form a line.
This „live‟ data trace is updated as data points are measured.
A memory trace is a live trace that has been stored in the FieldFox volatile
memory. It then becomes static, meaning it is not updated with measurements.
It can be displayed on the screen by itself, or with a data trace for comparison
purposes.
 In NA mode, memory traces are the same color as data traces, but muted
 In CAT mode, the data trace is displayed in yellow and the memory trace is
How to display data and memory traces

How to perform Trace Math
Trace math is performed between a data trace and a memory trace. When one of
the following math operations are selected, the data trace displays the current
measurement with the selected trace math applied. The math operation symbol
indicated below in [brackets] is displayed in the left pane.
