Much like other instrument or data acquisition VIs, these VIs “pass through” an instrument handle and error wires to make it easy to enforce execution order. The high-level VI should start with Initialize.vi and end with Close.vi, use the provided instrument handle with other VIs between intitialize.vi and close.vi.
Feel free to look into the VIs to see how they operate. They are found in the Public folder within \instr.lib, though the easiest way to access them is the functions palette under Instrument I/O, then Instr Drivers, then ASI TG-1000.
Please contact ASI if you find bugs or would like to see other features added!
