If you want filters with special characteristics, the custom design feature allows you to design
unique filters tailored to your specific needs. The required filter can be designed with a digital filter
design or with a math package such as MATLAB or Mathcad. Filter coefficients can be directly
downloaded from the program into the scope, using the DSOFilter utility. It is also possible to
specify the filter coefficients on an Excel spreadsheet and to use DSOFilter to download them
from the spreadsheet to the scope.
DFP2's flexibility is shown by the following example:
1. A 25 kHz square wave combined with an
unwanted 60 Hz sinusoidal component.
2. A high-pass filter set to attenuate signals
lower than 1 kHz is applied to remove the
unwanted 60 Hz component.
3. FFT of the unfiltered trace.
4. FFT of the filtered trace. Note the absence
of the 60 Hz component.
Enhanced Solutions
DFP2 can be coupled with other LeCroy software products such as JTA2 or DDM2 to enhance
the capabilities of these products and to provide improved solutions. For Jitter Measurement, for
example, the DFP2 Band-pass Filter can be coupled with the JTA2 package to measure jitter over
a narrow frequency range.
