The following is a list of equipment and software that is needed to do this quick MATLAB example. In the download below there is a txt file that has the instruction with where to place the MATLAB file and ADK files.  Equipment list: Windows 7 oscilloscope with firmware version 6.4 or later MATLAB with the Instrument Control Toolbox or any other toolboxes you will use (e.g. Signal Processing Toolbox). This example will show you how to update a txt file using the Application Development Kit (ADK) with values for your cutoff frequency. Then using a custom MATLAB filter file it will read in the values from this txt file and apply the appropriate butter worth 3 rd order filter with corresponding cutoff frequencies.  */
