Installation
Communicating Over the LAN
To launch the graphical web interface:
1. Open a Web browser on your computer.
2. Enter the instrument’s hostname or IP address into the browser’s Address field
to launch the graphical web interface. The B2900 home page will appear.
3. Click on the Browser Web Control button in the navigation bar on the left to
begin controlling your instrument.
4. For additional help about any page, click “Help with this Page”.
If desired, you can control the access to the graphical web interface using password
protection. As shipped from the factory, the password is set to Keysight, keysight, or
agilent. To change the password, click on the View & Modify Configuration button.
Refer to the online help for additional information about setting the password.
Using Telnet
The Telnet utility (as well as sockets), is another way to communicate with B2900
without using I/O libraries or drivers. In all cases, you must first establish a LAN
connection from your computer to the B2900 as previously described.
In an MS-DOS Command Prompt box, type “telnet hostname 5024” where
hostname is the B2900’s hostname or IP address, and 5024 is the instrument’s telnet
port. You should get a Telnet session box with a title indicating that you are
connected to the B2900. Type the SCPI commands at the prompt.
Using Sockets
NOTE Keysight B2900 allows any combination of up to four simultaneous data socket,
control socket, or telnet connections to be made.
Keysight instruments are standardized on using port 5025 for SCPI socket services.
A data socket on this port can be used to send and receive ASCII/SCPI commands,
queries, and query responses. All commands must be terminated with a newline for
the message to be parsed. All query responses will also be terminated with a
newline.
The socket programming interface also allows control socket connections. The
control socket can be used by a client to send device clear and to receive service
requests. Unlike the data socket, which uses a fixed port number, the port number
for a control socket varies and must be obtained by sending the following SCPI
query to the data socket: SYSTem:COMMunicate:TCPip:CONTrol?
