5 Software Overview
Once the XTR108EVM-USB starts up, several SPI communications take place to initialize the Interface
Board and read the XTR108 register values. Refer to Figure 18 for a screen shot of how the software
should appear if the EVM is functioning properly. The actual values of the fields inside the XTR108 block
diagram (such as PGA gain or I
LIN
DAC Linearization) may vary.
