Using Telnet to Send Commands

	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.
	If you need to control the GPIB using “device clear” or SRQ’s, you can
NOTE
	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 95.
	On unix:
	The syntax of the telnet command is:
	telnet <vsa hostname> 5023
	or
	telnet <IP address> 5023
	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
	When you connect to the instrument, it will display a welcome message
	and a command prompt.
	The instrument is now ready to accept your SCPI commands. As you
	type SCPI commands, query results appear on the next line. When you
	are done, break the telnet connection using the escape character (in this
	case Ctrl ]), and type quit.
	The analyzer responds with the a welcome message and the SCPI
	prompt. You can immediately enter programming (SCPI) commands.
	Typical commands might be:
	CONF:SPECTRUM
	CALC:SPECTRUM:MARK:TRACE SPECTRUM
	CALC:SPECTRUM:MARK:MAX
	CALC:SPECTRUM:MARK:MAX?
