VISA COM I/O Implementation Notes

Supported I/O Types

This implementation of VISA COM supports the GPIB::INSTR, GPIB::INTFC, TCPIP::INSTR, TCPIP::SOCKET, USB::INSTR, PXI::INSTR, and ASRL::INSTR resource types. Resource sessions of these types may be opened and used. 

Underlying VISA Library

The Keysight VISA COM library attempts to use Keysight VISA to perform its I/O operations. The Keysight VISA library is installed with all Keysight I/O hardware and with the Keysight IO Libraries Suite product; Keysight VISA supports any Keysight Technologies I/O product and can be configured to work with the gpib32.dll (NI-488) library. If the Keysight VISA I/O library is not installed, but some other VISA implementation is installed, the VISA COM I/O library may still function, but this configuration is not supported by Keysight Technologies. Consult the Keysight IO Libraries Suite Help for information on how to configure non-Keysight I/O hardware.
