I design a board with 4 channel ADC and 4 channel DAC.
i want ti test my board. what is the best test scenario to figure out my board problem.
how can i found that i captured data from my ADC's simultaneously.
To help with these questions, we will need to understand which DACs and ADCs you are using in your design. If you would like to be contacted offline to discuss the specifics, please include that request in your reply.
To see if your ADCs capture simultaneously feed them all with a sine wave from the same source and check for phase shifts in your capture streams. Assuming this is a high data rate application you will need to make sure that the electrical lengths of the four feeds are identical and it's best to use a 4:1 splitter with identical stub cables.
