Attribute Summary:
Description:
In the FFT analysis mode, the analyzer usually shows only the alias-protected data. For example, with
the frequency resolution set to 400 lines, the FFT size is 513 lines, but only the first 401 points are
displayed because the last 112 lines are in the anti-alias filter transition band. When the show all lines
mode is on and the anti-alias filters for all active channels are off, all the available frequency lines are
displayed.
The number of lines displayed when the show all lines mode is on can be calculated by :
where lines of resolution is 100, 200, 400, 800, or 1600. See the FREQ:RES command for more
information on lines of resolution.
Use the INP:FILT:LPASS command to turn the anti-alias filters off.
Note
Measurement results are not calibrated for flatness when the anti-alias filters are off.
