Hello,

unfortunately there is no offset trimming available at the A-156 module. P1,
P2 and P3 are just attenuators (with buffers) but do not offer an offset
feature. One would have to add an offset externally or modify the A-156 (by
adding trimming potentiometers and resistors for offset adjustment). I can
tell you details if required.

Best wishes
