HOW TO RUN THE SASWDP SCRIPT

The SASWDP script is required for running the Waveform Distortion Penalty (5.3.9) test. This script can

be obtained from the T10 organization website (http://www.t10.org/cgi-bin/ac.pl

). A valid T10 login is

required for downloading this download.

Note: As of March 2nd, 2014 this script can be found at the following site but this is subject to change:

http://www.t10.org/cgi-bin/ac.pl?t=d&f=09-015r0.zip

1. This script must be run from the same directory as the stressor, symbol and waveform data files.

• The stressor file is included when the script is downloaded from the T10 website (this file is

also included with QPHY-SAS3).

• The symbol and waveform data files are created when the WDP test is run from QPHY-

SAS3.

2. If MATLAB is installed on the oscilloscope:

• Unzip the 09-015r0.zip file to the D:\Waveforms\SAS3 directory.

i. The link to this file is provided above.

3. If MATLAB is installed on a separate PC

• Unzip the 09-015r0.zip to a temporary directory on the PC

• Copy the sas2_symbol.txt and sas2_waveformData.txt files to the same directory.

4. Run the SASWDP.m script.
