IP Address (LAN)  You can enter a static IP address for the 33210A as 
a four-byte integer expressed in dot notation ("nnn.nnn.nnn.nnn", where 
"nnn" in each case is a byte value from 0 to 255). Each byte is expressed 
as a decimal value, with no leading zeros (for example, 169.254.2.20). 
• You need not enter an IP address if DHCP or Auto IP is in use. 
However, If both DHCP and Auto IP fail to assign a valid IP address, 
the currently configured static IP Address is used.
• Contact your network administrator for a valid IP address to use for 
your function generator.
• Enter the IP address using the numeric keypad (not the knob).
• The IP address is stored in non-volatile memory and does not change 
when power has been off or after a remote interface reset.
• Front panel operation: Press  and press the I/O softkey. Select 
LAN, then Modify Settings, followed by IP Setup. By default, DHCP 
and Auto IP are On. Select DHCP Off and Auto IP Off. The IP 
Address field appears. Enter the desired address (for example: 
169.254.11.22).
• Remote interface operation: 
SYSTem:COMMunicate:LAN:IPADdress <address>
SYSTem:COMMunicate:LAN:IPADdress?
More About Dot Notation: Dot-notation addresses ("nnn.nnn.nnn.nnn" where "nnn" 
is a byte value) must be expressed with care, as most web software on the PC 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 33210A 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 PC web software to address the instrument. Do not use "255.255.020.011" - 
the PC will interpret this address differently due to the leading zeros.
