MATH[1]:DEFine
This command specifies the current math function as a text string. You must
also specify the type (dual waveform, FFT, advanced math, or spectrum math)
using MATH[1]:TYPe
Dual math expressions are strings of the form
<wfm> <o peration> <wfm>,
where the <wfm>s are any combination of live analog or reference waveforms
in the time domain display, the <operation> is any of +, -, * or /, and the type
has been se
tto
DUAL.
FFT math expressions are strings of the form
FFT(<wfm>), where <wfm> is any
live anal
og or reference waveforms in the time domain display, and the type has
been set to
FFT.
NOTE. You can also use FFT as part of a math expression by setting the type
to
ADVanced
using MATH[1]:TYPe. See examples of advanced type math
expressions below.
Advanced math expressions extend beyond dual math expressions, incorporating
combinations of advanced math functions, measurements, and operators.
Spectrum math (MDO models) expressions are strings of the form
<wfm><operation><wfm>, where the waveforms are any combination of live RF
or reference traces in the frequency domain display, the <operation> is either +
or –, and type has been set to
SPECTRUM.
