How is Prologix GPIB-USB controller different from other vendors?
While Prologix GPIB-USB controller provides many of the same features as GPIB-USB controllers from other vendors, it is much easier to use. Prologix GPIB-USB controller provides a virtual serial interface to communicate with instruments, while handling all GPIB protocol details for you. As a result, you can easily communicate with your instruments using a simple terminal program instead of having to write custom programs using a vendor supplied GPIB library. Please see the Manual for a complete list of features.
