Remote Interface Configuration
|
If you have the security option installed on your instrument, the instrument must be unsecured with the security code to perform many of these actions. |
The instrument supports remote interface communication over three interfaces: GPIB (optional), USB, and LAN (optional on 34460A). All three are "live" at power up when the instrument ships from the factory.
- GPIB Interface: Set the instrument's GPIB address and connect to your PC using a GPIB cable.
- USB Interface: Use the rear-panel USB connector to communicate with your PC. For details, see USB Settings.
- LAN Interface: By default, DHCP is on, which may enable communication over LAN. The acronym DHCP stands for Dynamic Host Configuration Protocol, a protocol for assigning dynamic IP addresses to networked devices. With dynamic addressing, a device can have a different IP address every time it connects to the network.
Connectivity Software
- The instrument ships with the Keysight Automation-Ready CD. This CD contains Keysight IO Libraries Suite software, which must be installed to enable remote-interface operations. The CD auto-starts and provides information on installing the software. Also includes Keysight Technologies USB/LAN/GPIB Connectivity Guide, which contains additional information.
GPIB Configuration
Each device on the GPIB (IEEE-488) interface must have a unique whole number address between 0 and 30. The instrument ships with a default address of 10, and the GPIB address is displayed at power-on.
- This setting is non-volatile; it will not be changed by power cycling or *RST or SYSTem:PRESet.
- Your computer’s GPIB interface card address must not conflict with any instrument on the interface bus.
- Front Panel: Press [Utility] > I/O Config > GPIB Settings. From this menu, you can set the GPIB address and turn GPIB on or off. After making changes, you must cycle power on the instrument for the change to take effect.
- SCPI:
SYSTem:COMMunicate:GPIB:ADDRess <address>
SYSTem:COMMunicate:ENABle {ON|1|OFF|0},GPIB
LAN Configuration
The following sections describe the primary front panel LAN configuration functions, including SCPI commands where applicable. Some LAN configuration functions can be performed only via SCPI. See SYSTem Subsystem - I/O Configuration for all LAN configuration commands, and see LAN Configuration Procedure to configure the LAN via the front panel.

Some LAN settings require you to cycle instrument power to activate them. The instrument briefly displays a message when this is the case, so watch the screen closely as you change LAN settings.

Resetting the LAN
You can clear the Web Interface password, turn DHCP on, and restart the LAN at any time:
- Front Panel:[Utility] > I/O Config > LAN Reset
The message "Performing LAN Reset" is displayed while the LAN is reset.
- SCPI: LXI:RESet
DHCP On/Off
DHCP (Dynamic Host Configuration Protocol) can automatically assign a dynamic IP address to a LAN device. This is typically the easiest way to configure the instrument for LAN.
- This setting is non-volatile; it will not be changed by power cycling or *RST or SYSTem:PRESet.
- Front Panel:[Utility] > I/O Config > LAN Settings > Modify Settings
Then set the first softkey to DHCP to use DHCP to automatically assign an IP address.
- SCPI: SYSTem:COMMunicate:LAN:DHCP {ON|1|OFF|0}
- If you change this parameter, you must either press the Apply Changes softkey (front panel) or send SYSTem:COMMunicate:LAN:UPDate (remote interface) for the change to take effect.
To manually set an IP address, Subnet Mask, or Default Gateway, turn DHCP off, then change the IP setup as described below.
IP Address
You can enter a static IP address for the instrument as a four-byte integer expressed in dot notation. Each byte is a decimal value, with no leading zeros (for example, 169.254.2.20).
- If DHCP is on, it attempts to assign an IP address to the instrument. If it fails, Auto-IP attempts to assign an IP address to the instrument.
- Contact your LAN administrator to obtain an IP address.
- This setting is non-volatile; it will not be changed by power cycling or *RST or SYSTem:PRESet.
- Front Panel:[Utility] > I/O Config > LAN Settings > Modify Settings
Then set the first softkey to Manual and press IP Address to enter a new IP address.
- SCPI: SYSTem:COMMunicate:LAN:IPADdress "<address>"
- If you change this parameter, you must either press the Apply Changes softkey (front panel) or send SYSTem:COMMunicate:LAN:UPDate (remote interface) for the change to take effect.
Subnet Mask
Subnetting allows the LAN administrator to subdivide a network to simplify administration and minimize network traffic. The subnet mask indicates the portion of the host address used to indicate the subnet.
- Contact your LAN administrator for details.
- This setting is non-volatile; it will not be changed by power cycling or *RST or SYSTem:PRESet.
- Front Panel:[Utility] > I/O Config > LAN Settings > Modify Settings
Then set the first softkey to Manual and press Subnet Mask to enter a new subnet mask with the arrow keys (for example: 255.255.0.0).
- SCPI: SYSTem:COMMunicate:LAN:SMASk "<mask>"
- If you change this parameter, you must either press the Apply Changes softkey (front panel) or send SYSTem:COMMunicate:LAN:UPDate (remote interface) for the change to take effect.
Default Gateway
A gateway is a network device that connects networks. The default gateway setting is the IP address of such a device.
- You need not set a gateway address if using DHCP.
- Contact your LAN administrator for details.
- This setting is non-volatile; it will not be changed by power cycling or *RST or SYSTem:PRESet.
- Front Panel:[Utility] > I/O Config > LAN Settings > Modify Settings
Then set the first softkey to Manual and press More and Gateway. Then set the appropriate gateway address using the arrow keys.
- SCPI: SYSTem:COMMunicate:LAN:GATeway "<address>"
- If you change this parameter, you must either press the Apply Changes softkey (front panel) or send SYSTem:COMMunicate:LAN:UPDate (remote interface) for the change to take effect.
Hostname
A hostname is the host portion of the domain name, which is translated into an IP address.
- The instrument receives a unique hostname at the factory, but you may change it. The hostname must be unique on the LAN.
- The name must start with letter; other characters can be an upper or lower case letters, numeric digits, or dashes ("-").
- This setting is non-volatile; it will not be changed by power cycling or *RST or SYSTem:PRESet.
- Front Panel:[Utility] > I/O Config > LAN Settings > Modify Settings
Then press Host Name and enter the hostname with the front panel arrow keys.
- SCPI: SYSTem:COMMunicate:LAN:HOSTname "<name>"
- If you change this parameter, you must either press the Apply Changes softkey (front panel) or send SYSTem:COMMunicate:LAN:UPDate (remote interface) for the change to take effect.
Domain Name
A domain name is a registered Internet name that gets translated into an IP address. You cannot set it from the front panel or SCPI.
DNS Server
DNS (Domain Name Service) is an Internet service that translates domain names into IP addresses. The DNS server address is the IP address of a server that performs this service.
- Normally, DHCP discovers DNS address information; you only need to change this if DHCP is unused or not functional. Contact your LAN administrator for details.
- This setting is non-volatile; it will not be changed by power cycling or *RST or SYSTem:PRESet.
- Front Panel:[Utility] > I/O Config > LAN Settings > Modify Settings
Then set the first softkey to Manual and press More and Primary DNS or Second DNS to enter a DNS address using the front panel arrow keys.
- SCPI: SYSTem:COMMunicate:LAN:DNS[{1|2}] "<address>"
- If you change this parameter, you must either press the Apply Changes softkey (front panel) or send SYSTem:COMMunicate:LAN:UPDate (remote interface) for the change to take effect.
Current Configuration (LAN)
- Press [Utility] > I/O Config > LAN Settings to view the MAC address and current LAN configuration. There is no equivalent SCPI command.
- If the instrument goes into remote, all LAN changes will be canceled and the display will go to a different screen. Re-selecting the LAN Settings page will display the new settings if a LAN restart took place.
Web Interface
The instrument includes a built-in Web Interface for remote instrument access and control over LAN via a Web browser. For details, see Web Interface.
