Add/Subtract Trace Math
:TRACe:MATH:ADD|SUBTract <destina-
tion_trace>,<source_trace1>,<source_trace2>
:TRACe:MATH?
Add or subtract the selected source traces and display the result as
destination trace.
Source_trace1, 2 are variable between trace1, 2, 3, 4 and the
display line.
Destination_trace is variable between trace1, 2, 3, and 4.
Note that a trace math mode is an enumeration; that is, when a
math function is set for a trace it turn off any math function that is
on for that trace and sets the new function.
The parameters sent in the command are reflected in the values in
the softkey menu. There is no default for any parameter; all 4
parameters must be sent to satisfy the parser. Failure to specify a
parameter will result in a missing parameter error.
The query returns the math mode, the operand traces, all
separated by commas.
Example: :TRACe:MATH:SUBTract TRACE1,TRACE2,TRACE3

Trace Math By
:TRACe:MATH:BY PWR|PLOG
This SCPI set trace sum or subtract by power or by power log. PWR
is by power(unit is W). PLOG is by power log(unit is dbm).
