Hi Rurik and Casparians, I have a problem with the data out of the adc5g yellow block and 2's complementary change and captured by a snapshot. It seems there is bit errors during the transmission, or it could be some other problem. This is roach2 with an adc5g clocked at 1400MHz, 2-channel, Nondemux (1:1) mode.
I tested it with a 175MHz sinusoid wave generated by a signal generator. The samples are predicted to be constant for every stream of the total 8 output streams with amplitude 32 within range (-128, 127), but I saw a lot of bit errors (bit flip? ). Attached are the time series of the 8 streams. Has anyone experienced this weird data? I'm appreciated of your attention and advice! Thanks! Weiwei
