4 Connecting the Instrument
This chapter describes how to connect the instrument to the power supply and external
devices.
Preventing electromagnetic interference
Use only suitable and double-shielded signal/control cables with at least 80 dB to
1 GHz shielding.
In particular cables that are connected to the ASI inputs and outputs can cause
EMC problems. Depending on the data rate and the packet timing of the transport
stream, high levels can occur sporadically within the signal spectrum.
The R&S DVMS can be used with different AC power voltages and adapts itself automatically to it. Adjusting the instrument to a particular AC supply voltage is therefore
not required. See the data sheet for the requirements of voltage and frequency.
Shock hazard
Observe the basic safety instructions at the beginning of this manual, especially the
instructions on electrical safety.
1. If you use the S/S2 receiver module (R&S DVMS‑B51), connect this module before
switching on the R&S DVMS (see Chapter 3.2.8, "S/S2 Receiver Module
(R&S DVMS-B51)", on page 21).
2. Connect the R&S DVMS to the AC power supply, using the supplied power cable.
The AC power connector is on the rear panel of the instrument.
Since the R&S DVMS complies with safety class EN61010‑1, connect it only to a
socket with a ground contact.
The R&S DVMS has no AC power switch. Therefore the R&S DVMS starts operating
when it is connected to the AC power supply. For further details, see Chapter 5.1,
"Switching On the Instrument", on page 26.
4.2 Connecting External Devices
Using the USB interfaces, you can directly connect USB devices to the R&S DVMS.
This number can be increased as necessary by using USB hubs.

Sample Application
Creating a Basic Configuration
6 Sample Application
Follow the instructions in this chapter to perform your first measurement with the
R&S DVMS.
For an expanded selection of measurement examples and background information,
refer to the user manual or the help system.
In this measurement, the R&S DVMS is used for basic compliance checks of one single MPEG2 transport stream (TS) signal.
Since the R&S DVMS base unit provides 4 baseband transport stream inputs (TS
IN/OUT 1...4, see Chapter 3.2.4.1, "TS IN/OUT 1 ... 4", on page 16), you can perform
the described measurement with every R&S DVMS independently of the number of
installed modules.
The DVB TS‑ASI input signal used in this measurement is generated by either a TS
generator (i.e. R&S DVSG) or by any other DVB-compliant TS‑ASI source.
The R&S DVMS is locally operated by using an LCD monitor (DVI input required, at
least 1024 x 768 pixels) and a USB mouse.
6.2 Setting Up the R&S DVMS
The required connectors are on the rear panel of the R&S DVMS. For details on the
connectors, see Chapter 3, "Interfaces and Connectors", on page 13.

7 Operating the R&S DVMS in a LAN
The R&S DVMS is equipped with a network interface and can be connected to an
Ethernet LAN (local area network). The network card operates with 10/100/1000
Base‑T Ethernet. 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
instrument that is connected must have a unique IP address or a unique computer
name. Access between different users is managed with access authorizations.
If the appropriate rights have been assigned and the Windows 7 firewall configuration
is adapted accordingly, you can use the interface for example for:
●
Transferring data
●
Printing on network printers
●
Operating/controlling the R&S DVMS from a remote computer
To use network resources, access must be granted. To share files on the R&S DVMS
with other network users, access to instrument 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, see the Windows 7 documentation). Contact your network administrator for access authorizations.
User name and password of the R&S DVMS are factory-set. The user name is used for
auto login, access authorization and remote operation.

7.1 Connecting the R&S DVMS to the Network
Risk of network failure/virus infection
Before connecting the R&S DVMS to the network or configuring the network, do the
following:
●
Consult your network administrator.
●
If your network does not support DHCP or if you choose to disable dynamic TCP/IP
configuration, you must assign valid address information before connecting the
R&S DVMS to the LAN.
Errors can affect the entire network.
Efficient virus protection is a prerequisite for secure operation in the network. Never
connect the R&S DVMS to a network without proper protection against a virus infection, as doing so can damage the instrument software.
To connect the R&S DVMS to the network
1. Fulfill all prerequisites mentioned above.
2. Make sure to switch off the R&S DVMS. This way you ensure that the R&S DVMS
detects the network connection reliably and works without any disruptions.
3. Connect the R&S DVMS to the network using a CAT‑7 RJ.45 cable.
To disconnect the R&S DVMS from the network
1. Make sure to switch off the R&S DVMS.
2. Disconnect the R&S DVMS from the network.
7.2 Connecting the R&S DVMS to a Computer
How to set up a LAN connection between an R&S DVMS and a single computer without integration into a larger network depends on the operating system installed on the
computer.
7.2.1 Windows 7 Operating System
If Windows 7 is installed on the computer, you can set up a LAN connection fast.
1. Activate DHCP on both the computer and the R&S DVMS.

2. Connect the computer and the R&S DVMS with a standard RJ.45 cross-over cable
(LAN cable).
After approx. 16 seconds, the connection is established.
3. To address the R&S DVMS, use the computer name.
Further information:
●
" Querying the computer name using the firmware" on page 39
If Windows 7 is not installed on the computer, you need to assign IP addresses.
1. Assign an IP address to the R&S DVMS 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.
2. Connect the R&S DVMS and the computer with a standard RJ.45 cross-over cable
(LAN cable).
3. To address the R&S DVMS, use the assigned IP address.
7.3 Configuring the Network Card
Under Windows 7, network card drivers do not need to be installed separately. If the
R&S DVMS 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. If
necessary, ask your network administrator.
If you are not familiar with LAN configurations, ask your network administrator.
Networks with DHCP server
The R&S DVMS is preconfigured for networks using the dynamic host configuration
protocol (DHCP). In such networks, the R&S DVMS is automatically assigned a free IP
address. Identification in the network is based on the use of a unique computer name.
Every instrument 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, see the Windows 7 documentation.

Configuring the Simple Network Management (SNMP) Agent
Querying the computer name using the firmware
In the firmware, "host name" is used as synonym for "computer name".
1. In the "Help" menu, click "About DVMS".
2. Under "Computer Name", 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: RS-DVMS4-100104
The serial number consists of 6 digits and is printed on the cabinet of the R&S DVMS.
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, see the Windows 7 help system.
7.4 Firewall Settings
By default, the Windows firewall is activated to protect the R&S DVMS from an attack
of hostile users and programs. The Windows firewall suppresses all network communication which is not initialized by the R&S DVMS itself or which is not defined as an
exception.
To enable data transfer or to allow access to the R&S DVMS, define exceptions using
the Windows 7 "Start" menu. For details, see the Windows 7 documentation or contact
your network administrator for support.
7.5 Configuring the Simple Network Management (SNMP) Agent
The "Instrument Configuration" dialog, "System Settings" tab gives access to the
SNMP configuration settings.
For details, see the user manual or help system, chapter "Configurations".

Operating System
8 Installed Software
The firmware and the operating system are already installed on the R&S DVMS.
For further information:
●
Performing a firmware update: see the release notes.
●
Installing software options: see the user manual or the help system.
The R&S DVMS is equipped with the Windows 7 Embedded operating system in the
32-bit version. When the R&S DVMS 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.
8.1.1 Login
Windows 7 requires that you identify yourself by entering a user name and password in
a login window. The R&S DVMS 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 DVMS 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.

Backup and Restore of the System Partition
The Windows 7 Start menu provides access to the Windows 7 functionality and the
installed programs. Under "Control Panel", the system settings are grouped. For
details, see the Windows 7 documentation.
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.
8.3 Backup and Restore of the System Partition
Before you start a backup or restore of the system partition, make sure that the hardware watchdog is disabled. See Chapter 8.3.1, "Prerequisite for Backup and Restore",
on page 41.
8.3.1 Prerequisite for Backup and Restore
As a prerequisite for the backup/restore process, in the BIOS settings, the hardware
watchdog must be disabled. Otherwise the backup/restore process (which normally
lasts about 10 to 15 minutes) will be terminated and fail due to a reboot issued by the
watchdog after about 4 minutes.
To disable the hardware watchdog
1. Connect an external keyboard to the USB interface.
2. Switch the R&S DVMS off and on again.
3. In the early boot phase when prompted at the bottom of the screen, press the DEL
key of the external keyboard.
The BIOS settings are displayed.

13. Continue as described in Chapter 8.3.2, "Backup and Restore Application",
on page 45.
After a successful boot with the default option "Firmware" in the boot dialog or a
restored backup, the hardware watchdog will automatically be re-enabled by the
R&S DVMS system software. Make sure that the required sequence as described
above is not interrupted for some reason. Otherwise restart at step step 2.
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.
Connect an external keyboard.
If the instrument does not have a monitor, connect also an external monitor.
To display the main dialog for backup and restore
1. Restart the R&S DVMS.
The boot screen is displayed. By default, "System" is selected. If you do not perform the next step within 4 seconds, the dialog vanishes and the booting process
continues.

9.1 Cleaning the Instrument
Maintenance
Replacing the Fuses
9 Maintenance
The R&S DVMS does not need periodic maintenance. 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 the beginning of this manual.
Shock hazard
Before cleaning the R&S DVMS, make sure that the R&S DVMS is disconnected from
all power supplies.
1. Clean the outside of the R&S DVMS using a soft, lint–free dust cloth.
2. Make sure that vents are unobstructed.
Instrument damage caused by cleaning agents
Cleaning agents contain substances that can damage the R&S DVMS, e.g. cleaning
agents that contain a solvent can damage the front panel labeling or plastic parts.
Never use cleaning agents such as solvents (thinners, acetone, etc.), acids, bases, or
other substances.
9.2 Replacing the Fuses
The R&S DVMS is protected by two fuses (IEC 127 – T 3.15 H/250 V) that are a part of
the AC power connector.
Shock hazard
Before replacing a fuse, make sure that the R&S DVMS is disconnected from all power
supplies.
Always use fuses supplied by Rohde & Schwarz as spare parts, or fuses of the same
type and rating.

9.3 Storing the Instrument
Maintenance
Storing the Instrument
To replace the fuses
1. Open the lid of the AC power connector.
2. Lift the fuse holder out of its slot.
3. Exchange the two fuses.
4. Put the fuse holder back in its slot.
5. Close the lid.
The storage temperature range of the R&S DVMS is given in the data sheet. If the
R&S DVMS is to be stored for a longer period of time, it must be protected against
dust.
Repack the R&S DVMS 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 DVMS from slipping inside the package. Wrap antistatic packing foil around the
R&S DVMS to protect it from electrostatic charging.
