Managing Filters
Managing Filters
Software defined filters can be applied to emulate a measurement
situation with lower bandwidth, or to obtain filter characteristics that are
theoretically perfect instead of hardware filters that change with time and
from unit to unit. On the Optical Sampling Oscilloscope, you can use the
following filters:
³
Bessel
³
Butterworth
³
Chebychev
You can set the order of the filter, and customize a bandwith over which
the filter is applied.
Note: The Chebychev filter is of Type 1, with a 1-dB ripple in the passband.
Note: You must be in pattern mode and use a repetitive sequence to use filters.
To add a filter to the sampling:
1. From the main window, select the Display menu, then Filtering.
2. Select the type of filter to apply. You can select only one type at a time.
