the GPIB remote control system are not available in control over
telnet server.
Control using C or Visual Basic
You can control the E5071C by socket programming using the C language
in the UNIX environment, or Visual C++ or Visual Basic in the Windows
environment.
For socket programming, the library for network connection on the TCP/IP
protocol is required. For the UNIX environment, BSD (Berkeley Software
Distribution) Sockets API is available; for the Windows environment,
WinSock (WinSock1.1 and WinSock2.0) created by porting BSD Sockets to
Windows and expanding it is available.
For more information on the control method, see a sample program for
control using WinSock described in "Controlling Using Telnet Server".
Control using Agilent VEE
Agilent VEE allows you to control the E5071C through the connection to the
socket of port 5025 using To/From Socket. The following figure shows an
example (when the IP address of the E5071C is 146.208.116.90). Enter
5025 in Host Name to specify the port for connection (1 in the following
figure) and enter the IP address or host name of the E5071C in the field to
specify the host name (2 in the following figure).
