Yesterday, I put two boards of LIGO-D1800304 with two pairs of circuits populated in each of them for testing.
As of today, I see that all sensors have reached a temperature which is within the sensing range of boards. However, I see different readings on them, probably due to different actual resistor value on each copy of circuit. The channels are being saved by fb4. I'll pull out time series data after some more time when we can safely assume that everything has thermalized. The fluctuations in the difference of these signals would tell us about environmental coupling and the board noise and precision itself.
