If you are having difficulty communicating with your instrument using the instrument driver VIs, use the Easy VISA IO VIs to test simple reads and writes interactively without running the VISA Open and VISA Close VIs. For example, for the Easy VISA Write VI, you only need to provide the resource name and the message to be sent to the instrument. The Easy VISA IO VIs include the following:
Although these Easy VISA IO VIs are convenient for testing purposes, they should be used with caution for application development. For each read or write to the instrument, these VIs always open and close a VISA session, which can slow down your application if called repeatedly. For this reason, it is best to use the standard VISA functions for application development.
