So are you using the drivers for the 4156C? The 41501B is only connected to the 4156C, correct? Does the 41501B need to be configured as well before you use both in LabVIEW? Technically you should only need the drivers for 4156C if that is the only thing connected to the computer. However, there may be some functionality that is not included in those drivers to automatically set up the 41501B that you would have to add to your program, if it is an available feature. This may require a bit of research on your part.
Hope this helps!
