L4400 User’s Guide 17
Configuring the L4400 Instruments
Instrument configuration as applied to the L4400 series of LXI instruments
involves the following:
• identifying the IP address and host name (LAN programming)
• (optional) setting the GPIB address
• testing the communication paths (LAN and/or GPIB) to the instrument
• opening the Web interface to the instrument
Each task listed above is accomplished using the Agilent Connection Expert
Feature of the Agilent IO Libraries Suite.
The information included this section of the chapter is:
• Selecting a LAN Network
• Connecting the LAN Cables
• Configuring the LAN Interface
• GPIB Configuration
Selecting a LAN Network
This user’s guide defines a private (isolated) LAN as a network in which
instrument access is limited to a direct connection between the computer and
the instrument, or to multiple instruments connected via a dedicated router or
switch. A site (company- wide) LAN is defined as a network in which
instrument access is available to many users in on-site and remote locations.
The instrument’s application and/or your company’s Information Technology
(IT) department may have guidelines that help decide the type (private or site)
of network used. If a network configuration has not been determined, refer to
the following considerations concerning each type.
Private LAN Considerations
Some of the basic parameters of a private LAN network to consider are:
security, performance, reliability, and IP address availability.
