DHCP
DHCP (Dynamic Host Configuration Protocol) is a protocol for
automatically assigning a dynamic IP address to a device on a network.
DHCP is typically the easiest way to configure your instrument for remote
communication using the LAN interface.
If you change the DHCP setting, you must cycle power on the 34980A to
activate the new setting.
• When DHCP is enabled (factory setting), the instrument will try to
obtain an IP address from a DHCP server. If a DHCP server is found, 
it will assign a dynamic IP address, Subnet Mask, and Default Gateway
to the instrument.
• When DHCP is disabled or unavailable, the instrument will use the
static IP address, Subnet Mask, and Default Gateway during power- on.
• If a DHCP LAN address is not assigned by a DHCP server, then a static
IP will be assumed after approximately 2 minutes.
• The DHCP setting is stored in non- volatile memory, and does not
change when power has been off, after a Factory Reset (
*RST
command), or after an Instrument Preset (
SYSTem:PRESet command).
