Here are the test results from today's ADC-DAC loopback tests. Channels 14 and 15 were the only ones behaving abnormally. Not sure what the issue is, but needs further debugging. The DAC output was as expected for both of them, but the corresponding ADC inputs were the same regardless of what offset was used (hovering around values of -4 and -5). NOTE: all measurements listed in the attached table are 'averages' in the sense that the ADC inputs and DAC outputs hovered around the listed values, changing by +1 or -1. |
