Hello,
I am working on a system with multiple ADS1282. There is a specific test configuration where a FPGA feeds a single sine ware to the inputs of all ADS1282 on the board. In one of the test runs, I have the following
The expected sine wave is present in all but one channel. When looking at the raw digital data, the noise on the third channel repeats (bit for bit) every 1024 samples. The spectral plot is below
The noise pattern is only seen once. I used the exact same configuration hundreds of times before and after. This noise pattern has never been repeated. Has anyone seen similar noise pattern before? Is the pattern something generated by ADS1282?
Regards,
Steve
