We are currently supporting old stand alone test equipment that is coming to the limit of it's service life. We are operating under DOS and the current number of test are greater that 200, so changing to a complete new operating system is not an option. We are looking at CPI, cCPI, and PXI. It appears that any one of the three would work for us, but which would have the largest selection of measuremnet devices, lowest cost, and long term support? I will have to create a interface driver that will intercept the GPIB calls of the old software and port them to the new test equipment, which of the three would be the best for this. Th
e test stations with new equipment and the old equipment must function the same with only a change in the linking libraries.
