Using the LAN to Control the Analyzer

Refer to the User’s Guide “Using System Features” chapter for information about configuring the analyzer input/output settings from the front panel. Use the SYSTem commands to change settings remotely.

Remember that in any type programming using LAN you should avoid constantly opening and closing connections. This uses up processing resources, adds to your system overhead, and can cause problems with asynchronous implementation of successive commands. When you are sending the instrument multiple commands: open the connection, send all the commands, and close the connection.

Using ftp for File Transfers

File transfers can be done using the instrument LAN connection. For example, you can use the ftp functionality to download instrument screen dumps to an external server.

A sample ftp session might be:

ftp 15.88.163.118 (<instrument IP address>)

At the name prompt enter:

vsa

At the password prompt enter:

service

You are now in the instrument /users directory and can get files from the analyzer. Type in help at the prompt to see the ftp commands that are available on your system. Typing quit will end your ftp session.

Do NOT delete files from this directory. Most of the files are required for the instrument, and it’s optional personality modes, to operate.
