The button labeled “Load External Pattern File” is used to select the test pattern file to be loaded into the board memory. Clicking on this button opens a navigator which the user will select the desired test file. The format of the test file can be either .csv or .tsw. Once selected, the file is loaded into the PC memory used by the GUI.
The imported file must be text format integer value from – 2^ (Number of Bits -1) to 2^ (Number of Bits -1) – 1 in a single column format if testing a single DAC. For dual DACs, the file must be in 2 columns. For quad DACs, 4 columns. The length can be from 4096 to 512M (single column) in increments of 32 for the TSW1400 and TSW14J5x. The GUI comes with several example test files that can be found under the following directory:
C:\Program Files\Texas Instruments\High Speed Data Converter Pro\Test files.
Note: Number of Bits = Sample Resolution.
