:CALCulate<1|2>:MATH<1 to 4>[:EXPression][:DEFine] <expr>
This command defines the mathematical expression for relating traces and reference line. Command
CALCulate:MATH:STATe switches the mathematical relation of traces on or off .
Parameter: <expr>::= ‘OP1 - OP2 [ + RLINE]’
OP1 ::= TRACE1 | TRACE2 | TRACE3 | TRACE4
OP2 ::= TRACE1 | TRACE2 | TRACE3 | TRACE4 | RLINE
Examples: ":CALC:MATH1 (TRACE1 - TRACE3 + RLINE)"
":CALC:MATH4 (TRACE4 - RLINE)"
Features: *RST value: -
SCPI: conforming
Modes: A, VA
The operand [+ RLINE] may be used only if OP2 is different from RLINE. The numeric suffix in
CALCULATE<1|2> is not significant. The numeric suffix in MATH<1 to 4> denotes the trace where
the result of the mathematical operation is stored. The number must be identical to the number of the
operand OP1.
:CALCulate<1|2>:MATH<1 to 4>:STATe ON | OFF
This command switches the mathematical relation of traces on or off.
Example: ":CALC:MATH1:STAT ON"
Features: *RST value: OFF
SCPI: conforming
Modes: A, VA
The numeric suffix in CALCULATE<1|2> is not significant. The numeric suffix in MATH<1 to 4>
denotes the trace which the command refers to.
