R&S ESU Remote Control – Description of Commands
CALCulate Subsystem
6.5.5 CALCulate:MATH Subsystem
The CALCulate:MATH subsystem allows to process data from the SENSe-subsystem in numeric expres-
sions.
The measurement windows are selected by CALCulate1 (screen A) and CALCulate2 (screen B).
CALCulate<1|2>:MATH[:EXPression][:DEFine] (<expr>)
This command defines the mathematical expression for relating traces to trace1.
The CALCulate<1|2>:MATH:STATe command switches the mathematical relation of traces on or off.
The measurement windows are selected via CALCulate1 (screen A) or 2 (screen B).
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: conform
Mode: A-T
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-T
CALCulate<1|2>:MATH:STATe ON | OFF
This command switches the mathematical relation of traces on or off.
The measurement windows are selected via CALCulate1 (screen A) or 2 (screen B).
Example:
"CALC:MATH:STAT ON"
'Switches on the trace mathematics in screen A.
Characteristics: *RST value: OFF
SCPI: conform
Mode: A-T
