At this moment, DCRC v2 can do SQUID tuning on all channels. I can see phonon signal on channel D after closing the loop. Channel A and C will saturate after closing the loop. Channel B has no phonon signal. I will send the board to Fermilab next Monday after chatting with Sten.

UPDATE: The phonon signal seen on channel D maybe in open loop mode. I'm confused. They need to be checked again at Fermilab.
