Downgrade to a firmware version < 1.90
Instruments shipped with a REFBOARD version > 001_000_000 cannot be downgra-
ded to a firmware version < 1.90 simply by executing the related firmware setup file.
Please contact R&S service if you plan such a downgrade.
See the
for the REFBOARD version of your instrument.
12.1.2
Remote operation in a LAN
A LAN connection is used to integrate the analyzer into a home/company network.
LAN connectivity offers several applications, e.g.:
●
Transfer data between a controller and the analyzer, e.g. to run a remote control
program.
●
Control the measurement from a remote computer using Remote Desktop or a sim-
ilar application.
●
Use external network devices (e.g. printers).
The analyzer uses a user name and password as credentials for remote access; see
note on
"User accounts and password protection"
on page 34 for details. To protect the
analyzer from unauthorized access, it is recommended to change the factory setting.
12.1.2.1
Assigning an IP address
Depending on the network capacities, the TCP/IP address information for the analyzer
can be obtained in different ways.
●
If the network supports dynamic TCP/IP configuration using the Dynamic Host
Configuration Protocol (DHCP), all address information can be assigned automati-
cally.
●
If the network does not support DHCP, or if the analyzer is set to use alternate
TCP/IP configuration, the addresses must be set manually.
By default, the analyzer is configured to use dynamic TCP/IP configuration and obtain
all address information automatically. Hence it is safe to establish a physical connec-
tion to the LAN without any previous analyzer configuration.
Manual TCP/IP configuration
If your network does not support DHCP, or if you choose to disable dynamic TCP/IP
configuration, you must assign valid address information
before
you connect the ana-
lyzer to the LAN. Contact your network administrator to obtain a valid IP address,
because connection errors can affect the entire network.
Admin account
You need administrator rights to change the TCP/IP configuration. See note on
accounts and password protection"
