NOTE: This definition can be applied only to Function F. It will be
executed only if Function E is defined as FFT (any display mode). The
number of points will be that of the output of the FFT (i.e. N/2).
Examples:
RDF,FFT,MAG,1250,CI
Redefines the SELECTed trace (E or F) for the
FFT of Channel 1 with maximum 1250 points,
displaying the Magnitude on a linear scale.
Default settings are applied to the
remaining parameters (Rectangular window,
m fact = 1.0, a const = 0.0, zero suppression
ON).
RDF,FFT,PNS,625,C2,BH,2.0,,OFF
Redefines the SELECTed trace (E or F) for the
FFT of Channel 2 with maximum 625 points,
displaying the Power Spectrum on a
logarithmic (dBm) scale. Window Type
Blackman-Harris, m fact = 2.0, a_const = 0.0,
zero suppression is OFF.
RDF,FFTA,PWD,20
Redefines the SELECTed trace (must be F) for
the FFT Power Average of the FFT computed
simultaneously by Function E. Number of
sweeps is 20.
11.4.2 Additional Values in the Descriptors of FFT Processed Waveforms
The oscilloscope waveform and descriptors can be read into a host
computer (see Section 7.6.5).
With the WP02 option, the Waveform Descriptor length is unchanged
(150 bytes). However, in addition to the Descriptor field values defined
in Section 7.7 and 10.4, the following fields have new or additional
values pertaining to the results of FFT processing:
