But the circuit and its properties differ significantly. One important aspect: Where the 66309D only has…

HP 6060B System DC Electronic Load: Adjustment

Sure, for a unit capable of 60 A that seems reasonable, and well within its specs of ±0.1% ±75 mA. But since I’ll use…

This option certainly is not unheard of, but not too common either. Retrofitting is possible, but can be quite some work.…
