SYSTem:COMMunicate:LAN:IPADdress
Syntax
SYSTem:COMMunicate:LAN:IPADdress <address>
SYSTem:COMMunicate:LAN:IPADdress? [{CURRent|STATic}]
Description
This command assigns a static Internet Protocol (IP) Address for the 34980A. Contact your network administrator for a valid IP address to use for your instrument.
|
|
If you change the IP address, you must cycle power on the 34980A to activate the new address. |
Parameters
|
Name |
Type |
Range of Values |
Default Value |
|
<address> |
Numeric |
Specified in four-byte dot notation ("nnn.nnn.nnn.nnn"), where "nnn" in each case is a byte value in the range 0 through 255. |
169.254.9.80 |
Remarks
If DHCP is enabled (see SYSTem:COMMunicate:LAN:DHCP command), 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.
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 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 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. 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).
Return Format
The query command returns the IP address in the form "nnn.nnn.nnn.nnn".
Note that the query command has two optional parameters. Specify "CURRent" (default) to read the dynamic IP address currently being used by the instrument. Specify "STATic" to read the IP address currently stored in non-volatile memory within the instrument (may not be the actual address used by the instrument if DHCP is enabled).
Examples
The following command sets the IP address.
SYST:COMM:LAN:IPAD 255.255.25.14
The following query returns the IP address currently being used by the instrument (the quotes are also returned).
SYST:COMM:LAN:IPAD? CURR or SYST:COMM:LAN:IPAD?
Typical Response: "169.254.149.35"
