CALCulate<Chn>:MATH[:EXPRession][:DEFine] <Expression>
Defines a simple mathematical relation between traces. To calculate and display the
new mathematical trace, the mathematical mode must be switched on
(
CALCulate<Chn>:MARKer<Mk>[:STATe] ON
).
Note: This command places some restrictions on the mathematical expression and the
operands. Use
CALCulate<Chn>:MATH[:EXPRession]:SDEFine
to define general
expressions.
Suffix:
<Chn>
.
Channel number used to identify the active trace.
Parameters:
<Expression> <expr>
(
<operand1><operator1><operand2>[<operator2>
<operand3>]
) The expression must be enclosed in brackets.
Operands: See list of trace names in Chapter 7.3.19, "TRACe
Commands" , on page 1174.
Operators: +, -, *, /
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 (CH1DATA / MDATA2)
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.
DIAGnostic:SERVice:FUNCtion <SFId1>, <SFId2>...
Activates a service function (mainly for internal use). Service functions are identified by
groups of numbers, separated by dots.
Parameters:
<SFId1>
<SFId2> Service function identifier entered as a (pseudo-)numeric value,
the dots being replaced by commas. Five groups of numbers are
allowed at maximum. See also
DIAGnostic:SERVice:
SFUNction
.
FORMat:DEXPort:SOURce <Format>
Defines the format for traces retrieved with the R&S ZVR-compatible command
TRACe[:DATA][:RESPonse][:ALL]?
.
This command is not relevant for results read with the
CALCulate<Chn>:DATA...
commands.
