gn 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 Teledyne 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.
