Show FFT segment filter slopes ( Ctrl-i )
This option is a diagnostic aid intended for use when editing FFT segment table files for
phase noise and AM noise acquisition with the PhaseStation 53100A or TimePod 5330A.
When acquiring noise plots on the PhaseStation 53100A, data for each visible FFT
segment undergoes highpass and/or lowpass filtering based on the declarations in the
segment table
, accessible via the Additional options page in the 53100A acquisition
dialog. By rendering the entire extent of each segment record, Trace → Show FFT
segment filter slopes ( Ctrl-i ) provides a visual display of the filter skirts for each
segment, as well as the overlap between them. In this mode, you can temporarily hide
the skirts by holding the
Shift
key.
For detailed information about the segment table’s format and contents, refer to the
comments within the default segment table file. This file can be accessed by pressing
the
Additional options button in the 53100A acquisition dialog, followed by Edit
segments .
Most users will not need to edit the segment table.
