1.2 ADS131B26Q1EVM-PDK Quick-Start Guide
The following instructions are a step-by-step guide to connecting the ADS131B26Q1EVM-PDK to the computer
and evaluating the performance of the ADS131B26-Q1:
1. Review the default jumper settings in
and GUI software installation in
2. Connect the ADS131B26Q1EVM-PDK to the PHI controller. Install the two screws as indicated in
3. Connect the PHI controller to your PC using the provided USB micro cable. Three LEDs illuminate on the
PHI controller to indicate connectivity to the PC.
a. LED D5 lights up solid, indicating that the PHI is powered up.
b. LEDs D1 and D2 start blinking at different rates to indicate that the PHI is booted up and communicating
shows the resulting LED indicators.

4. Launch the ADS131B26Q1EVM-PDK GUI software and power is supplied to the EVM. The default
installation path is
C:\Program Files (x86)\Texas Instruments\ADS131B26-Q1 EVM
.
5. When the GUI finishes loading and is connected to the EVM hardware, the screen appears as illustrated in
. The GUI consists of multiple
Pages
, which include:
• Register Map Config
• Time Domain Display
• Spectral Analysis
• Histogram Analysis
• Channel Configurations
• Sequencer Configurations
Below the
Pages
section are the basic SPI op-code commands, the
