Accessing Operating System
The operating system cannot be accessed.
All necessary system settings can be made in the "Setup" dialog.
2.6.1 Connecting the Instrument to the Network
There are two methods to establish a LAN connection to the instrument:
●
A non-dedicated network (Ethernet) connection from the instrument to an existing
network made with an ordinary RJ-45 network cable. The instrument is assigned an
IP address and can coexist with a computer and with other hosts on the same net-
work.
●
A dedicated network connection (Point-to-point connection) between the instrument
and a single computer made with a (crossover) RJ-45 network cable. The computer
must be equipped with a network adapter and is directly connected to the instrument.
The use of hubs, switches, or gateways is not required, however, data transfer is still
performed using the TCP/IP protocol.
In both cases, an IP address has to be assigned to the instrument and the computer, see
chapter 2.6.2, "Assigning the IP Address"
The R&S SMC uses the IP addresses 192.168.xxx.yyy for this purposes, where xxx and
yyy may take values between 1...254; the subnet mask is always 255.255.255.0.
Risk of network failure
Before connecting the instrument to the network or configuring the network, consult your
network administrator. Errors may affect the entire network.
► To establish a non-dedicated network connection, connect a commercial RJ-45 cable
to one of the LAN ports.
To establish a dedicated connection, connect a (crossover) RJ-45 cable between the
instrument and a single PC.
If the instrument is connected to the LAN, the operating system automatically detects the
network connection and activates the required drivers.
The network card can be operated with a 10/100 Mbps Ethernet IEEE 802.3u interface.
2.6.2 Assigning the IP Address
Depending on the network capacities, the TCP/IP address information for the instrument
can be obtained in different ways.
●
If the network supports dynamic TCP/IP configuration using the Dynamic Host Con-
figuration Protocol (DHCP), all address information can be assigned automatically.
