Math = Data/Mem
Activates the mathematical mode where the active data trace is divided by the last generated memory
trace. The division is calculated on a point-to-point basis: Each measurement point of the active trace is
divided by the corresponding measurement point of the memory trace. The result of the division is a
mathematical trace and replaces the active data trace in the diagram area. The mathematical trace is
updated as the measurement goes on and the analyzer provides new active trace data.
This function is disabled unless a memory trace is coupled to the active data trace. Trace coupling
ensures that the two traces have the same number of points so that the mathematical trace Data/Mem .
Math = Data/Mem and Math = User Def are alternative options of the mathematical mode.
Selecting one option disables the other. The mathematical expression defined via User Def Math is not
affected.
Remote control: CALCulate<Ch/Tr>:MATH[:EXPRession]:SDEFine <string>
CALCulate<Ch/Tr>:MATH:STATe ON
Show Data
Displays or hides the active data trace in the diagram area. If one of the mathematical options Math =
Data/Mem or Math = User Def are active, then the active mathematical trace is displayed or hidden.
Remote control: No command, display configuration only.
Show Mem
Displays or hides the active memory trace in the diagram area or the memory trace associated with the
active data trace.
•
If no memory trace is associated with the active data trace, Show Mem is disabled.
•
If several memory traces are associated with the active data trace (see -> Mem) , Show Mem
affects the last generated or changed memory trace.
Remote control: No command, display configuration only.
More Mem
Opens a submenu to store traces as memory traces, show or hide traces. The submenu complements
the Data -> Mem menu command.
