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).

IP Address

An Internet Protocol (IP) Address is required for all IP and TCP/IP communications with the instrument. If DHCP is enabled (factory setting), the specified static IP address is not used. However, if the DHCP server fails to assign a valid IP address, the currently configured static IP address will be used.

If you change the IP address, you must cycle power on the 34980A to activate the new setting.

• The default IP Address for the 34980A is “169.254.9.80”.
