From the files menu, load the configuration file:
TAS5132DDV2EVM Configuration (1.00).cfg
The file is located on the TAS5132DDV2EVM CD-ROM. This file contains all settings for a default setup of
the EVM.
For easy access of the file, it is recommended to copy the files into directory where the GUI is installed.
Default is C:\Program Files\Texas Instruments Inc\TAS5086\.
For more advanced use of the GUI and the features of the TAS5086 modulator, see the GUI User’s Guide
and the TAS5086 data sheet (SLES131 ). The GUI User's Guide can be accessed by clicking on Help in
the toolbar and then selecting User's Guide in the drop-down menu.
