I need to create a stair step analog function to control a galvonometer. I am trying to scan a small chip with a laser. I have one galvo to move side to side and one to move down the chip. I currently use a triangle wave on a rising slope but this causes the system to zig-zag across the chip. I would much rather have the side to side galvo scan straight across the chip.
Could you please elaborate as to how you are using the PCI-6229 to achieve this and why it is a problem to have the "side to side galvanometer" scan straight across the chip.
