Subject: offset voltage vs. gain of common mode servo 

At 1Y2 rack, I measured offset voltage of the common mode servo (D040180-B) with the gain of it varied.

For now, all signal cables that come into or go out of the common mode servo are not plugged.

 

I will upload the data I took and report the result later.
