Resolving Network Connection Failures

Several issues may cause failures in the network connection to the instrument. This section lists the most likely reasons and the recommended solutions.

Common reasons for network connection failures
  • Network connecting cables and cable connectors of poor quality
  • Incompatibility between the network interface of the R&S SMA and certain switches or routers available on the market
  • An invalid IP address assigned to the instrument
Possible solutions

Risk of connection errors

Before configuring the network, changing IP addresses or exchanging hardware, consult your network administrator.

Connection errors can affect the entire network.

  • Check the network infrastructure. Exchange connecting cables if obvious damage is visible.
  • Observe the link status LED on the connected network device. The link status LED is located next to the LAN connector.
    If a link failure is detected, connect the instrument to a different device port or to a different network device.
  • Check whether the LAN interface and the required LAN services are enabled.
    See "LAN Services".
  • Check whether the IP address of the instrument is within the network's address range.
    See "Network Settings ".
    Check whether IP addresses that were set manually or obtained via the Zeroconf (APIPA) protocol are valid.
