Function Commands 16

Agilent Infiniium 90000 Series Oscilloscopes Programmer's Reference 303

:FUNCtion<N>:FFTMagnitude

Command :FUNCtion<N>:FFTMagnitude <operand>

The :FUNCtion<N>:FFTMagnitude command computes the Fast Fourier

Transform (FFT) of the specified channel, function, or memory. The FFT

takes the digitized time record and transforms it to magnitude and phase

components as a function of frequency.

<N> An integer, 1 - 4, representing the selected function.

<operand> {CHANnel<n> | DIFFerential<P> | COMMonmode<P> | FUNCtion<n> |

WMEMory<n> | <float_value> | MTRend | MSPectrum}

See the discussion of possible operands in the introduction to Chapter 16,

“Function Commands,” starting on page 287.

Example This example sets up function 1 to compute the FFT of waveform memory
