"√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 498
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
).
Envelope wfm selection
Selects the upper or lower part of the input waveform for mathematic calculation, or a
combination of both.
Remote command:
CALCulate:MATH<m>:ENVSelection on page 500
8.2.3 Math filter
Access:[Math] > "Filter" tab
The finite impulse response filter is a filter to create filtered math waveforms with low-
pass or highpass. The filter requires additional settings.
In remote control, filter settings are defined in the expression string, see CALCulate:
MATH<m>[:EXPRession][:DEFine] on page 498.
