Label
Adds a label to the math waveform.
Operator
Defines the type of operation to be performed on the selected signal sources.
The following functions are available:
"+"
Adds the values of 2 sources (channel or math waveform).
"-"
Subtracts source 2 from source 1.
"x"
Multiplies the two sources.
"/"
Divides source 1 by source 2.
"1/x"
Calculates the reciprocal of the source.
"- x"
Calculates the negative value of the source.
"|x|"
Determines the absolute value of the source.
"Δx/Δt"
Differentiates the source value relating to the time value.
Not possible on envelope waveforms and waveforms with "Peak
detect" decimation.
"Integral"
Calculates the definite integral of the source.
"log(x)"
Calculates the logarithm of the source value based on 10.
"ln(x)"
Calculates the natural logarithm of the source value (based on e).
"ld(x)"
Calculates the binary logarithm of the source value (binary logarithm,
based on 2).
"x
2
"
Squares the source. If the source contains negative values that have
been clipped, then the result contains positive clipping.
"√x"
Calculates the square root of the source. Note that the square root of
a negative number is undefined and the result is clipped.
"Rescale"
Rescaling of x.
Remote command:
CALCulate:MATH<m>[:EXPRession][:DEFine] on page 527
Source 1, Source 2
Defines the signal source to be evaluated by the math function.
a, b
Defines the values for the rescale function, if "Operator" = "Rescale"
"a"
Multiplication factor
"b"
Offset of the signal source on the y-axis.
Noise reject
Only available for "Operator" = "dx/dt".
Sets the number of neighboring samples that are skipped for differentiation.
To suppress noise effects during differentiation, it can be useful not to consider two
directly neighboring points to calculate dx (x
n
-x
n-1
). Instead, some samples in-between
are skipped and a point a few samples further is used (e.g. x
n
-x
n-3
).
