CALCulate:MATH Subsystem
The CALCulate:MATH subsystem allows to process data from the SENSe-subsystem in numeric
expressions. The measurement windows are selected by CALCulate1 (screen A) or CALCulate2
(screen B).

CALCulate<1|2>:MATH[:EXPression][:DEFine] <expr>
This command defines the mathematical expression for relating traces to trace1.
The zero point of the result display can be defined with CALC:MATH:POS. Command
CALCulate:MATH:STATe switches the mathematical relation of traces on or off .
Parameter: <expr>::= ‘OP1 - OP2’
OP1 ::= TRACE1
OP2 ::= TRACE2 | TRACE3
Example: "CALC1:MATH (TRACE1 - TRACE2)" 'Selects the subtraction of trace 1
'from trace 2 in screen A.
"CALC2:MATH (TRACE1 - TRACE3)" 'Selects the subtraction of trace 1
'from trace 3 in screen B.
Characteristics: *RST value: -
SCPI: conforming
Mode: R, A
CALCulate<1|2>:MATH:POSition -100PCT to 200PCT
This command defines the position of the result of the trace mathematics in the selected
measurement window. The indication is in % of the screen height, with 100% corresponding to the
upper diagram border.
Example: "CALC:MATH:POS 50PCT" 'Sets the position in screen A to the
'horizontal diagram center.
Characteristics: *RST value: 50 %
SCPI: device-specific
Mode: A
