I notice a different behaviour of my position sensing detector, PSD (PDP90A, Thorlabs) when reading AIs connected to a BNC-2110 and SCB-68A blocks. My suspicion is that the grounding options (Floating source and Ground reference for BNC-2110) are different for the 2 blocks. I can change the ground option on the BNC-2110, but have no idea how it works on SCB-68A. The difference in signal, read by the position sensing detector, is a strong signal delay visible when using the compact SCB-68A block. Do you have any idea how I could use SCB-68A with the performance of BNC-2110?
