I need to measure C end-to-end à la the @SIY method. Present calculation is measured arm cable, measured interconnect, parasitic of the board from the designer, data sheet for the opamp, and some allowance for connectors, rounded up to the nearest quarter nF. The interconnect is only 14”, though STP. Even so, shaving a few inches off isn’t going to matter.Also, I think the lowest possible capacitance would help in this case. 100 pF total is possible if cabling is optimized.
(Would be interesting to see the V15V JICO SaS/B with 30k)
I’ve SAS B, S, R, and Z for the V. Some day I’ll measure them all and play with loading. It just never makes it on to the priority list.
