This sample program does an identification (*IDN?) query to a LAN-connected instrument via the Windows Sockets (Winsock) I/O API.
Date: December 1, 2004
Version: 1.00
Programming Language: C in Microsoft® Visual Studio® (Using the Winsock 2 communication API)
Required Instrument: Any LAN-enabled instrument with raw TCP socket capabilities and a *IDN? response (33220A, for example.)
Operating Systems Required: Windows® 98, Windows Me, Windows NT® 4.0, Windows 2000, Windows XP
Usage Instructions:
Unzip the Visual Studio project into a "clean" directory and open the project. Change the IP address in the RawSocketComm.c file to the IP address of a LAN instrument that can respond to a *IDN? query and supports raw TCP/IP socket communication. The VISA resource name for such instruments is of the form "TCPIP::hostname::portnumber::SOCKET". Compile and execute the program.
Other Information:
Any I/O API that supports raw TCP (Transmission Control Protocol) socket communication can be used for a program equivalent to this one. Agilent recommends the VISA I/O Library in either the C-language or COM (Component Object Model) API format for instrument communication. However, when VISA is not available or usable for some reason, raw TCP socket communication via a native operating system-provided I/O API such as Winsock is often possible with Agilent's LAN-connected instruments. See the Agilent IO Libraries Suite documentation for more information on LAN communication and VISA.
