Troubleshooting the Initial Connection
Getting the analyzer to work with your network often requires detailed
knowledge of your local network software. This section attempts to help
you with some common problems. Contact your network administrator
for additional assistance.
The analyzer LAN interface does not need or include any proprietary
driver software. It was designed to operate with common network
utilities and drivers.
Either a hardware problem or a software problem can prevent the
analyzer's remote file server from communicating over the LAN. The
following common problems may be encountered:
Communications Not Established If you have just installed and
configured the LAN interface and you have never been able to access
the analyzer via ftp or telnet, go directly to “Pinging the Analyzer
from Your Computer or Workstation” on page 119.
If you have previously been able to access the analyzer via ftp or
telnet and now cannot do so, check the following:
❏ Has any hardware been added or moved on your network? This
includes adding or removing any workstations or peripherals, or
changing any cabling.
❏ Have software applications been added to the network?
❏ Has the functionality been turned off from the front panel? Press
System, Config I/O, SCPI LAN.
❏ Have any configuration files been modified? Pressing
System,
Restore Sys Defaults restores the original factory defaults and you
will have to re-set the instrument IP address and hostname.
❏ Is the upper- and lower-case character usage in your hostname
consistent?
