[dsg-hdice] Dilution fridge card

Mon Apr 15 11:06:55 EDT 2019

Hi Xiangdong,

Tyler, Pablo, and I took a look at the dilution fridge card on Friday and we noticed that the card was receiving 30V as opposed to 24V, the correct voltage the card should be receiving.  The 30V seems to be coming directly from the power supply.  We cannot access the power supply to take a closer look at it.

We then connected 24V to the card to test how the card behaved.  The resistors that were overheating no longer overheated with the 24V supply.

Regards,

Amanda
