I am trying to evaluate the AD7960. We have designed a dedicated board for testing the device on the ATE system. We have to extract all static and dynamic parameters. The stimulis are a sinus or a ramp generating by AWG 24bits.
But something wrong. Codes is missing. and I don't understand why. I verified all the ATE system. The algorithm to compute the data is certified.
Here is my setup:
E0 to E3: 1001
2.048V to REFIN
Convertion rate: 4MSPS
Any Hints on what is going on would be welcome.
