Figure E 14: Representative Filter Characteristics
These filters can be used to eliminate extraneous components of the waveform
and to reduce the foldback component when there are a small number of
waveform points. Specifically, these filters reduce the jaggedness of the
waveform and raise the S/N ratio. The rising and falling time for the waveform
when it is not passed through the filters is about 4 ns.
Time Difference from SYNC Signals with Each Filter. Filters have their own unique
delay time. This time difference with the SYNC signals, marker signals, and
other output signals can be varied by changing the filter value.
Table E-3 shows the delay relative to the sync signals caused by the filters.
