<x> ?
MATH<x>:DEFINE
Allows the user to define new waveforms using mathematical expressions. This
is equivalent to selecting Change Math waveform definition in the Math<x>
side menu.

MATH<x>
<QString> contains the mathematical expression. The expression can include
any amount of white space. Expressions can be either single or dual waveform
expressions. <src> and <function> elements are case independent.
The format for a single waveform expression is:
<function>(<source> [, <window>, <scaling>, <phase
suppression>])
The format for a dual waveform expression is:
<source><operator><source>
where:
<function> ::= INV | DIF | FFT | INT
H INVert (for invert): inverts the defined waveform.
H DIFferentiate (available with Advanced DSP Math only): takes the
derivative of the selected waveform.
H FFT (available with Advanced DSP Math only): provides an FFT of the
selected waveform. It uses the format: “FFT(<source>, <window>,
<scaling>, <phase suppression>)” where the window, scaling, and phase
suppression arguments in the parentheses are optional. You can specify these
arguments in any order.
