Command
:FUNCtion<N>:FFTPhase <source>
The :FUNCtion<N>:FFTPhase command computes the Fast Fourier Transform
(FFT) of the specified channel, function, or waveform memory. The FFT takes
the digitized time record and transforms it into magnitude and phase
components as a function of frequency.
<N>
An integer, 1 - 4, representing the selected function.
<source>
{CHANnel<n> | FUNCtion<n> | WMEMory<n> | <float_value>}
CHANnel<n> is:
An integer, 1 - 2, for two channel Infiniium Oscilloscopes.
An integer, 1 - 4, for all other Infiniium Oscilloscope models.
FUNCtion<n> and WMEMory<n> are:
An integer, 1 - 4, representing the selected function or waveform memory.
<float_value> is:
A real number from -1E6 to 1E6.
Example
This example sets up function 1 to compute the FFT of waveform memory 3.

Functions Used as Operands
A function may be used as a source for another function, subject to the following
constraints:
F4 can have F1, F2, or F3 as a source.
F3 can have F1 or F2 as a source.
F2 can have F1 as a source.
F1 cannot have any other function as a source.
