Get Started with TCP/IP Interface for VXI-11 and HiSLIP
The TCP/IP interface is supported through a VISA-TCP/IP object. The features
associated with a VISA-TCP/IP object are similar to the features associated with a
tcpclient object. Therefore, only functions and properties that
are unique to VISA's TCP/IP interface are discussed in this section. Both VXI-11 and
HiSLIP protocols are supported.
Refer to TCP/IP Communication Overview for more information about TCP/IP communication.
Create VISA-TCP/IP Object
Create a VISA-TCP/IP object with the
visadev function. Each object is associated with an instrument
connected to your computer.
visadev requires the resource name or alias as an input. The
resource name consists of the name of the TCP/IP board index, IP address or host
name, and LAN device name of your instrument. You can find the VISA-TCP/IP resource
name or alias for a given instrument with the configuration tool provided by your
vendor or with the
visadevlist function. Define the alias using your VISA vendor
The VISA-TCP/IP resource name has the format
For example, use the VISA-TCP/IP interface to connect to an instrument at IP address 169.254.2.20 using the VXI-11 protocol.
visatcpip = visadev("TCPIP0::169.254.2.20::inst0::INSTR")
visatcpip = TCPIP with properties: ResourceName: "TCPIP0::169.254.2.20::inst0::INSTR" Alias: "Keysight_33210A" Vendor: "Agilent Technologies" Model: "33210A" LANName: "inst0" InstrumentAddress: "169.254.2.20" Show all properties, functions

You can use dot notation to configure and display property values. For more information about configuring these properties, see visadev Properties.
You can communicate with your instrument using the
