Page 34: Configuring The Lan Interface
Configuring the LAN Interface By default, LAN connectivity with DHCP (Dynamic Host Configuration Protocol) is enabled on the 33502A. In many cases you can simply let DHCP assign the necessary parameters for a LAN connection. However, you can also turn off DHCP and set parameters manually. -
Page 35: Ip Address
Subnet Mask. • Changing the Subnet Mask setting will cause an automatic LAN reset. • The default Subnet Mask for the 33502A amplifier is “255.255.0.0”. • A value of “0.0.0.0” or “255.255.255.255” indicates that subnetting is not being used. -
Page 36: Default Gateway
• The default for the amplifier is “0.0.0.0” (no gateway, and subnetting is not being used). • The Default Gateway 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. Keysight 33502A User/Service Guide... -
Page 37: Host Name
IP address. • Changing the Host Name will cause an automatic LAN reset. • The default Host Name for the amplifier is “A–33502A–nnnnn”, where nnnnn is the last five digits of the instrument’s serial number representation. • If Dynamic Domain Name System (DNS) is available on your network and your amplifier uses DHCP, the Host Name is registered with the Dynamic DNS service at power–on. -

Instrument Preset (SYSTem:PRESet) command. Instrument Unexpectedly Goes into Remote If your 33502A unexpectedly goes into remote mode, it is likely because you have the instrument configured to the LAN on someone else’s host controller. Operations on that host controller can query your instrument causing it to go into remote mode. -
