Chapter 9.1, "Connecting the R&S BTC to a Network", on page 40

●

Chapter 9.2, "Connecting the R&S BTC to a Computer", on page 41

6.1 Preventing Electromagnetic Interference

To prevent electromagnetic interference, the R&S BTC must be operated with all
shielding covers fitted. Only suitable and shielded signal and control cables may be
used.

RF/marker/trigger/reference inputs and outputs

In particular cables that are connected to these inputs/outputs can cause EMC prob­lems. Therefore these cables should have at least 80 dB to 1 GHz shielding. This is
usually achieved by means of double-shielded cables.

USB interfaces

To connect the USB interfaces, only use peripheral equipment that does not cause limit
violations. For information on the interface, see Chapter 5.2.5, "USB Interfaces",
on page 23.

TS serial inputs

To connect the TS serial inputs, use double-shielded cables. A termination impedance
of 50 Ω is required.

Display port interface

To connect the display port interface, only use peripheral equipment that does not
cause limit violations. For information on the interface, see Chapter 5.2.2, "DISPLAY

PORT", on page 22.

DVI interface

To connect the DVI interface, use a cable shielded with ferrite cores. For information on
the interface, see Chapter 5.2.3, "DVI Port", on page 22.

LAN interface

To connect the LAN interface, use a suitable cable. For information on the interface,
see Chapter 5.2.4, "LAN", on page 22.

All other cables can be single shielded. The AC cable is unshielded.

9 Operating the R&S BTC in a LAN

The R&S BTC is equipped with a network interface and can be connected to an Ether­net LAN (local area network). The network card operates with 1000 Mbit Ethernet
IEEE 802.3ab. The TCP/IP network protocol and the associated network services are
preconfigured.

To be able to exchange data within a local area network (LAN), every computer or
R&S BTC that is connected must have a unique IP address or a unique computer
name. Access between different users is managed with access authorizations.

Provided the appropriate rights have been assigned and the Window 7 firewall configu­ration is adapted accordingly, the interface can be used e.g. for transferring data, print­ing on network printers, operating/controlling the R&S BTC from a remote computer.

To use network resources, access must be granted. To share files on the R&S BTC
with other network users, access to R&S BTC resources, e.g. the hard drives, must
also be granted. All these administration tasks are normally performed by a network
administrator using the Windows 7 Start menu (for details refer to the Windows 7 docu­mentation). Contact your network administrator for access authorizations.

User name and password of the R&S BTC are factory-set. The user name is used for
auto login, access authorization and remote operation.

network connection is reliably detected and any disruptions during the operation of
the R&S BTC are avoided.

3. Connect the R&S BTC to the network using a CAT-5e cable or better.

4. Switch on the R&S BTC.

To disconnect the R&S BTC from a network

1. Make sure that the R&S BTC is switched off.

2. Disconnect the R&S BTC from the network.

9.2 Connecting the R&S BTC to a Computer

BTC to a Computer

How to set up a LAN connection between an R&S BTC and a single computer without
integration into a larger network depends on the operating system installed on the
computer.

9.2.1 Windows 7 Operating System

If Windows 7 is installed on the computer, you can set up a LAN connection really fast.

1. Activate DHCP on both the computer and the R&S BTC.

2. Connect the computer and the R&S BTC with a standard RJ.45 cross-over cable

(LAN cable).

After approx. 16 seconds, the connection is established.

3. To address the R&S BTC, use the computer name.

Further information:

●

" Querying the computer name using the firmware" on page 42

9.2.2 Other Operating Systems

If Windows 7 is not installed on the computer, you need to assign IP addresses.

1. Assign an IP address to the R&S BTC and the computer.

The IP addresses 192.168.xxx.yyy are available for use here. xxx and yyy can
assume values of 1 to 255. The value for the subnet mask is 255.255.255.0.

Configuring the Network Card

2. Connect the R&S BTC and the computer with a standard RJ.45 cross-over cable

(LAN cable).

3. To address the R&S BTC, use the assigned IP address.

9.3 Zero Configuration Networking

The R&S mDNS service is installed with the firmware. Using this service, you can con­nect to a network automatically. You do not need to set up services, such as dynamic
host configuration protocol (DHCP) and domain name system (DNS), or configure the
network settings manually as described in Chapter 9.4, "Configuring the Network

Card", on page 42.

9.4 Configuring the Network Card

Under Windows 7, network card drivers do not need to be installed separately. If the
R&S BTC is connected to the LAN, Windows 7 automatically detects the network con­nection and activates the required drivers.

The configuration tasks depend on whether your network has a DHCP server or not.
They are performed in Windows 7.

If you are not familiar with LAN configurations, ask your network administrator.
If you use the R&S mDNS Service, you do not need to configure at all. For details, see

Chapter 9.3, "Zero Configuration Networking", on page 42.

Networks with DHCP Server

The R&S BTC is preconfigured for networks using the dynamic host configuration pro­tocol (DHCP). In such networks, the R&S BTC is automatically assigned a free IP
address. Identification in the network is based on the use of a unique computer name.

Every R&S BTC is assigned an individual computer name at the factory. It is displayed
as part of the window title of the application.

If necessary, you can change the computer name using the Windows 7 Start menu (for
details refer to the Windows 7 documentation).

Querying the computer name using the firmware

In the firmware, "host name" is used as synonym for "computer name".

1. If the R&S BTC has a default computer name, the computer name is displayed in

the title bar of the application.

2. If no default computer name is displayed, do the following.

a)

In the toolbar, tap
b) On the "System" tab, under "LAN Services", select the "Host Name" field.

3. Read out the name.

Naming rule for the default computer name

The default computer name is composed as follows:

<instrument short name>-<serial number>

Example: BTC-100104

The serial number consists of 6 digits and is printed on the cabinet of the R&S BTC.

Networks without DHCP Server

In networks that assign fixed IP addresses, the network administrator usually config­ures the network card. Contact your network administrator. The IP address is set using
the Windows 7 Start menu (for details refer to the Windows 7 documentation).

9.5 Firewall Settings

By default, the Windows Firewall is activated to protect the R&S BTC from an attack of
hostile users and programs. The Windows Firewall suppresses all network communi­cation which is not initialized by the R&S BTC itself or which is not defined as an
exception.

To enable data transfer or to allow access to the R&S BTC, define exceptions using the
Windows 7 Start menu. For details refer to the Windows 7 documentation or contact
your network administrator for support.

The firmware and the operating system are already installed on the R&S BTC.

Further information:

●

Performing a firmware update: see the release notes.

●

Installing software options
See the installation instructions for options or the user manual.

The R&S BTC is equipped with the Windows 7 Embedded operating system in the 32­bit version. When the R&S BTC is delivered, the operating system is configured for
optimum operation. Changes to the system settings are required only if you install
peripherals such as a keyboard and printer or if you configure the network and the set­tings do not conform to the default settings.

Risk of causing instrument unusability

To prevent malfunctions and to avoid instrument repair, only install service packs
approved by Rohde & Schwarz.

In particular, do not use service packs for other Windows 7 editions.

10.1.1 Login

Windows 7 requires that you identify yourself by entering a user name and password in
a login window. The R&S BTC provides a factory–installed auto login function, i.e. login
is carried out automatically in the background. The ID used for auto login has adminis­trator rights.

User name and password are factory-set as follows.

●

User name = instrument

●

Password = 894129

If the R&S BTC is connected to a network and if the user name and the password are
identical under Windows 7 and on the network, you log on to operating system and the
network at the same time.

Risk of causing instrument unusability

The instrument is equipped with the Windows 7 operating system. Additional software
can therefore be installed on the instrument. The use and installation of additional soft­ware may impair instrument function. Thus, run only programs that Rohde & Schwarz
has tested for compatibility with the instrument software.

The drivers and programs used on the instrument under Windows 7 have been adap­ted to the instrument. Existing instrument software must always be modified using only
update software released by Rohde & Schwarz.

.

10.3 Backup and Restore Application

Using the backup and restore application, you can back up the instrument installations
and their configuration so that they can be restored if necessary. When restoring, you
can choose between various states.

●

Factory default state
If, for example, the system crashes, you can restore the factory default state.

●

Intermediate states that you have saved
For example, you can back up the current system partition before a firmware
update or provide different system configurations for different environments.

In the restore process, the system partition is deleted, formatted and written newly. The
data partition is not affected.

Cleaning the Instrument

11 Maintenance

The R&S BTC does not need a periodic maintenance unless it is operated in dusty
areas.

Risk of instrument damage

If the R&S BTC is operated in dusty areas, the fans may become obstructed by dust or
other particles in the process of time. Make sure to check and, if necessary, clean the
fans regularly to ensure they operate properly at all times. If the R&S BTC is run with
obstructed fans for a longer period, it may become overheated which may cause dam­age.

Clean the outside of the instrument when necessary and check the rated data from
time to time.

If any problem arises, contact one of our customer support centers. The addresses of
our customer support centers are provided at www.customersupport.rohde-

schwarz.com.

11.1 Cleaning the Instrument

Shock hazard

Before cleaning the R&S BTC, make sure that the R&S BTC is switched off and dis­connected from all power supplies.

1. Clean the outside of the R&S BTC using a soft, lint-free dust cloth.

2. Make sure that vents are not obstructed.

Instrument damage caused by cleaning agents

Cleaning agents contain substances that may damage the R&S BTC, e.g. cleaning
agents that contain a solvent may damage the front panel labeling or plastic parts.

Never use cleaning agents such as solvents (thinners, acetone, etc), acids, bases, or
other substances.

Storing the Instrument

11.2 Storing the Instrument

The storage temperature range of the R&S BTC is given in the data sheet. If the
R&S BTC is to be stored for a longer period of time, it must be protected against dust.

Repack the R&S BTC as it was originally packed when transporting or shipping. The
two protective foam plastic parts prevent the control elements and connectors from
being damaged. The antistatic packing foil avoids any undesired electrostatic charging
to occur.

If you do not use the original packaging, provide for sufficient padding to prevent the
R&S BTC from slipping inside the package. Wrap antistatic packing foil around the
R&S BTC to protect it from electrostatic charging.
