Operating Manual 1145.1084.12 – 30 662
Define a mathematical trace, dividing the data trace by the stored memory trace.
The mathematical trace is not displayed
CALC:MATH:STAT ON
Display the mathematical trace instead of the active data trace.
CALCulate<Chn>:MATH[:EXPRession]:SDEFine '<string>'
Defines a general mathematical relation between traces. To calculate and display the new mathematical
trace, the mathematical mode must be switched on (CALCulate<Chn>:MATH:STATe ON).
<Chn>
Channel number used to identify the active trace.
'<string>'
String parameter for the mathematical expression, enclosed in brackets. The string
format must correspond to an allowed string in the Define Math dialog.
Parameters
Operands, operators and functions; see table below.
*RST value

Command
Types
Device-specific, command or query. This command also queries a mathematical
expression defined via CALCulate<Chn>:MATH[:EXPRession][:DEFine].
Example:
*RST; :CALC:MATH:MEM
Copy the current state of the default trace Trc1 to a memory trace named
'Mem2[Trc1]'. The memory trace is not displayed.
CALC:MATH:SDEF 'Trc1 / Mem2[Trc1]'
Define a mathematical trace, dividing the data trace by the stored memory trace.
The mathematical trace is not displayed.
CALC:MATH:STAT ON
Display the mathematical trace instead of the active data trace.
Expressions defined via CALCulate<Chn>:MATH[:EXPRession]:SDEFine may contain the following
