2Features and Functions

•Dot- notation addresses (“nnn.nnn.nnn.nnn” where “nnn” is a byte value) must be expressed with care, as most web software on the computer will interpret byte values with leading zeros as octal numbers. For example, “255.255.020.011” is actually equivalent to decimal “255.255.16.9” not “255.255.20.11” because “.020” is interpreted as “16” expressed in octal, and “.011” as “9”. To avoid confusion, use only decimal expressions of byte values (0 to 255), with no leading zeros.

For example, the 34980A assumes that all dot- notation addresses are expressed as decimal byte values and strips all leading zeros from these byte values. Thus, attempting to set an IP address of “255.255.020.011” will become “255.255.20.11” (a purely decimal expression). Be sure to enter the exact expression, “255.255.20.11”, in your computer web software to address the instrument. Do not use “255.255.020.011” — the computer will interpret this address differently due to the leading zeros.

•If you are planning to use a static IP address on a Corporate LAN, contact your network administrator to obtain a fixed IP address to be used exclusively for your instrument.

•The IP address 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).

Auto-IP

The Auto- IP standard automatically assigns an IP address to the 34980A when on a network that does not have DHCP servers.

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

•Auto- IP allocates IP addresses from the link- local address range (169.254.xxx.xxx).

•From the factory, the Auto- IP setting is enabled.

•The Auto- IP 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).
