Programming Fundamentals
Using the LAN to Control the Analyzer
Using Telnet to Send Commands
Using telnet to send commands to your analyzer works in a similar way
to communicating over GPIB. You establish a connection with the
analyzer, and then send or receive information using SCPI commands.
NOTE If you need to control the GPIB using “device clear” or SRQ’s, you can
use SICL LAN. SICL LAN provides control of your analyzer via IEEE
488.2 GPIB over the LAN. See “Using SICL LAN to Control the
Analyzer” on page 106. in this chapter.
On unix:
The syntax of the telnet command is:
telnet <vsa hostname> 5023
or
telnet <IP address>
The initial telnet connection message will be displayed and then a
SCPI> prompt. At the SCPI prompt, simply enter the desired SCPI
commands.
On a PC:
You would type at the dos prompt
telnet
The telnet gui has the host/port setting menu.
Unix Telnet Example:
To connect to the instrument with host name my4406 and port number
5023, enter the following command:
telnet my4406 5023
NOTE You must have changed your instrument host name from the default
(for example, change E566DD69 to my4406) in order to specify your
instrument by name. Press
System, Config I/O, Host Name.
Alternately, you can enter the IP address directly in the telnet
command, in place of the analyzer name:
telnet 15.4.45.255 5023
