    Communicating Over the LAN Using the Graphical Web Interface Your Keysight B2961A/B2962A has a built-in graphical web interface that lets you control it directly from an Web browser on your computer. Multiple simultaneous connections are allowed, but only from one computer. With additional connections, performance will be reduced.

  • Page 97: Using Telnet

    Using Telnet The Telnet utility (as well as sockets), is another way to communicate with B2961A/B2962A without using I/O libraries or drivers. In all cases, you must first establish a LAN connection from your computer to the B2961A/B2962A as previously described.
  • Page 98 To send a device clear, send the string “DCL” to the control socket. When the B2961A/B2962A has finished performing the device clear, it will echo the string “DCL” back to the control socket. Service requests are enabled for control sockets using the Service Request Enable register.
