Remote programming and operation of the instrument is accomplished via raw socket programming over Ethernet or the GPIB. The following paragraphs provide general information about interface language, utilizing VISA, interface connections, and cable requirements.
VISA is an I/O software standard for communicating with test instruments, like the MG362x1A, over any of the bus architectures which the MG362x1A supports. Anritsu recommends NI-VISA, the National Instruments implementation of the VISA I/O standard.
Note
Use the full version of NI-VISA (not just the runtime) for the best support of the latest .NET Framework, USB, and TCP/IP updates. Check with National Instruments for details.
The MG362x1A LabVIEW driver uses VISA to communicate. VISA uses connection strings to set up communication with the MG362x1A over various protocols. Some examples include:
//Raw Socket Connection string
"TCPIP0::192.168.1.7::9001::SOCKET";
//GPIB Connection string
"GPIB0::6::INSTR";
To communicate with the MG362x1A, note either the IP address or GPIB address of the signal generator and then set up a resource using the appropriate connection string.
Interface Connectors
When using Ethernet connectivity, the interface between the signal generator and other devices is through an RJ45 connector and a standard CAT-5 or CAT-7 Ethernet cable. For instruments on the GPIB, connectivity is established via a 24-wire interface cable. This cable uses connector shells having two connector faces. These double-faced connectors allow for the parallel connection of two or more cables to a single device.
