USB connections
The following figure illustrates a typical USB interface system.
1. Connect your instrument to the USB port on your computer using a USB cable.
2. With the Connection Expert utility of the Keysight IO Libraries Suite running, the computer will automatically
recognize the instrument. This may take several seconds. When the instrument is recognized, your computer will
display the VISA alias, IDN string, and VISA address. This information is located in the USB folder. You can also view
the instrument's VISA address from the front panel menu.
3. You can now use Interactive IO within the Connection Expert to communicate with your instrument, or you can
program your instrument using the various programming environments.
The USB cable is not recommended to be longer than 3 meters.
LAN connections - site and private
A site LAN is a local area network in which LAN-enabled instruments and computers are connected to the network
through routers, hubs, and/or switches. They are typically large, centrally-managed networks with services such as
DHCP and DNS servers. The following figure illustrates a typical site LAN system.
1. Connect the instrument to the site LAN or to your computer using a LAN cable. The as-shipped instrument LAN
settings are configured to automatically obtain an IP address from the network using a DHCP server (DHCP is ON by
default). The DHCP server will register the instrument's hostname with the dynamic DNS server. The hostname as
well as the IP address can then be used to communicate with the instrument. The front panel LAN indicator will
come on when the LAN port has been configured.
If you need to manually configure any instrument LAN settings, refer to
for information about configuring the LAN settings from the front panel of the instrument.
2. Use the Connection Expert utility of the Keysight IO Libraries Suite to add the electronic load and verify a
connection. To add the instrument, you can request the Connection Expert to discover the instrument. If the
instrument cannot be found, add the instrument using its hostname or IP address.
