Pressing the Shift key and then Trace (5) key brings up the Trace main menu. The trace math feature supports Trace Overlay to allow viewing two traces at the same time to compare a stored trace to a live trace.
Trace Math operations include Trace - Memory. It is possible to copy a trace to display memory directly from the Trace menu. Traces can also be recalled from internal memory or downloaded from Master Software Tools into the instrument and compared with live traces.
