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