Ethernet Summary

VISA provides a cross-platform API for programming Ethernet instruments. Other APIs provide the same Ethernet functionality and implement additional protocols, so if you are familiar with them, then there is not a strong reason for you to change to VISA. However, if you have instruments with more than one type of port or connection available to them (such as TCP/IP and GPIB on the same instrument), or are using multiple types of instruments with different hardware interface types, then using VISA may be advantageous because you can use the same interface independent API regardless of the connection medium. The only code that changes is the resource string.
