•

 Step 

1 

Install the LabVIEW Run-time Engine  

LabVIEW85RuntimeEngineFull.exe

 

 (if not already installed). 

 

•

 Step 

2 

Start the LabVIEW application “ADC1x13.exe”. a graphical window will pop-up 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Under the “ Write register from command file” field, choose the write configuration file from “ADC Command” 
directory  depending on the used operating points.  

 

 

 

 

 

 

Click on the “read from config file”. 

Push the Push_A button on the board to make a manual synchronization of the JESD204A communication. 

 

 

 

 

 

 

 

Fill the Input Frequency and Clock Frequency fields with the wanted operating points.
