Step 5. Press ] while holding down Ctrl in the telnet screen to break the connection to
the E4980A/AL. The telnet prompt appears. Type “quit” at the telnet prompt
and press Enter to finish using telnet.
Control from a program (using port 5025)
When controlling the E4980A/AL from a program on the external controller,
use the socket of port 5025 for connection.
Control using C or Basic
You can control the E4980A/AL by socket programming using Visual Studio in
a Windows environment.
For socket programming, the library for network connection on the TCP/IP
protocol is required. For a UNIX environment, BSD (Berkeley Software
Distribution) Sockets API is available; for a Windows environment, WinSock
(WinSock1.1 and WinSock2.0), created by porting BSD Sockets to Windows
and expanding it, is available.
Control using Keysight VEE
Keysight VEE allows you to control the E4980A/AL through the connection to
the socket of port 5025 using the To/From Socket. Figure 8-5 shows an
example (when the IP address of the E4980A/AL is 192.168.1.101). Enter
“5025” in the field to specify the port for connection (1 in Figure 8-5) and enter
the IP address of the E4980A/AL in the field to specify the host name (2 in
Figure 8-5).
