11.1
FAST FOURIER WAVEFORM PROCESSING OPTION
(WP02, V 2.06FT)
Processing Capabilities
The FFT option (WP02) adds a spectrum analysis capability to a 9400A
already equipped with the waveform processing option WP01.
The 9400A’s Functions E and F can be defined as the fast Fourier
transform of one of the source waveforms - Channel 1, Channel 2, Memory
C, Memory D, and Function E (for Function F only). A glossary of the
terms used in this chapter is given in Section 11.6.
Values of the following FFT processing parameters can be selected in
the FFT redefine menu or with remote control commands.
