Programming with VISA 3
Agilent VISA User’s Guide 37
The following table illustrates the format of the rsrcName
for different VISA interface types. INSTR is an optional
parameter that indicates that you are communicating with a
resource that is of type INSTR, meaning instrument. The
keywords are:
•ASRL - used for asynchronous serial devices.
•GPIB - used for GPIB devices and interfaces.
•GPIB-VXI - used for GPIB- VXI controllers.
•TCPIP - used for LAN instruments.
•VXI - used for VXI instruments.
•USB - used for USB instruments.
