The following advanced parameters are available:
●
"mDNS and DNS-SD": The additional protocols "multicast DNS" and "DNS service
discovery" are used for device communication in zero configuration networks,
working without DNS and DHCP.
●
"ICMP Ping": Must be enabled to use the ping utility.
If you disable this setting, the instrument does not answer ping requests. The set-
ting does not affect the LXI ping client. You can ping other hosts from the instru-
ment, even if the setting is disabled.
●
"VXI-11 Discovery": Must be enabled to detect the instrument in the LAN.
If you disable this setting, the instrument cannot be detected by the VXI-11 discov-
ery protocol mechanism. The setting does not affect other detection mechanisms.
Setting up a VXI-11 connection via the IP address or the host name is independent
of this setting.
Password protection
Changing the LAN configuration is password-protected and requires the security pass-
word. The default password is "instrument".
10.5.3.3
Ping Client
The "Ping Client" page provides the ping utility to verify the connection between the
LXI-compliant instrument and another device.
The ping is initiated from the instrument. Using the
ICMP
echo request and echo reply
packets, the function checks whether the communication with a device via LAN is
working. Ping is useful for the diagnosis of IP network or router failures.
To initiate a ping at the instrument:
1. On the "Ping Client" page, enter the IP address of the host in the "Destination
Address" field (for example 10.111.0.125).
2. Select "Submit".

SCPI Remote Trace
The remote trace functionality allows you to trace input and output strings at the
remote control interface of the R&S
SGU, see
Chapter 10.5.4, "How to Record SCPI
Commands and Messages exchanged via the LXI Web Browser Interface"
A recorded trace (message log) can be evaluated directly in the dialog. Use the high-
lighting and navigation functions provided by the lower toolbar to locate error mes-
sages and messages containing arbitrary search strings. You can also export the mes-
sage log to a
*.csv
file and evaluate the file using a suitable program.
To trace and display messages, switch on "logging" and "live mode" in the toolbar.
