I have also noticed that the interface will show up as unknown and with a yellow question mark icon in the VISA Interactive Control tool.SolutionThis error indicates that control of the VISA resource (e.g., the serial port, GPIB port, Ethernet port, etc.) could not be taken. It can oc...
On this basis, the NI-VISA programming interface is used to define the order of magnitude of the serial port bytes, the imported data information is processed by configuring the remote serial port, and the program block diagram system is combined to realize...
If you have both NI and Agilent/HP controllers in the same system, you must configure the cards at different system addresses, such as GPIB0 and GPIB1. If both vendors try to use the same interface address, NI-VISA reports an error fromviFindRsrcor VISA Find Resources. ...
