[dsg-hdice] Found a built in averaging and referencing feature on sweep tab of Zurich lock-in amplifier

[Xiangdong Wei]

Hi Tyler,

After reviewing the UITF run plans, I just realized that we need to remotely drive 2 independent Oxford superconducting magnet power supplies at the same time, not just 1.

Would you please check to see if it is possible to add another VI to Rack 2 computer to realize this mode?

Thanks,

Xiangdong
