One thing I have to say about working with bonafide NI GPIB controllers is that the driver software v15, v16 &v17 are free and very extensive. If you are at all familiar with Basic, c or c++, the MS Visual Community tool set is free and very easy to use for GPIO programming.
Further, NI includes numerous utility programs such as the GPIB tracer app that lets you monitor all transactions on the GPIB bus.
