¸SFU Broadcast Test System
One-box solution
Test transmitter
RF signals for a variety of analog and digital transmission standards can be transmitted over a wide,
­user-­variable frequency range by the integrated test
transmitter. It is easily possible to switch over between the different standards for terrestrial, satellite, or cable transmission. The software is reloaded
to provide the multistandard test transmitter functionality, and a highly accurate spectrum is generated.
Bit error ratio meter
The integrated BER meter makes it possible to measure and evaluate errors on the transmission link.
A BER value can be determined on the transport
stream in parallel or serially as well as via the serial
data and clock circuits.
Channel simulator
Integrated transmission simulators for AWGN,
phase noise, impulsive noise and fading are available for simulating real and, above all, reproducible
environmental conditions in the lab.
Transport stream signal source
Video and audio applications require baseband signals. A variety of transport stream or analog ­video
signals are available as transport stream signal
sources.
◆ Rohde & Schwarz libraries with ready-to-use special signals for tests and development can be
­replayed with the transport stream and video
generator.
◆ Customer files can be easily loaded and replayed
with the transport stream player.
◆ The internal transport stream recorder supports
recording of customer transport streams from
any sources.
¸SFU Broadcast Test System
I/Q signal generator
Customer I/Q waveforms or Rohde & Schwarz waveform libraries for different transmission standards
can be replayed with the arbitrary waveform generator.
Power measurement
High-precision power measurements with ­power
sensors from Rohde & Schwarz can be performed
and displayed on the R&S®SFU's large screen.
High output power
High output levels and signal amplifiers are usually
required in production. The R&S®SFU provides this
high output power with its high power option.
I/Q interface
The digital I/Q interface provides the high-quality
I/Q signals that are required in development as
­input and output signals. The instrument also features an analog I/Q interface and an I/Q wideband
input that allows I/Q signals to be fed directly to the
modulator.
¸SFU Broadcast Test System
Coders
020260775421451
All realtime coders are software-based;
you can activate them immediately by
means of an enabling code (see right).
It is thus not ­necessary to open the
­instrument.
PAL B/G
Cable standards
Satellite standards
DVB-C
The DVB-C coder supports all QAM modulations defined in the EN 300429 standard. The powerful coder hardware is
­also able to cover high-order QAM modulations that have not yet been standardized.
DVB-S, DVB-S/DSNG
DVB-S (EN 300421/EN 301210) was introduced in 1994 as a satellite transmission standard. DVB-S uses QPSK modulation. Since its introduction, DVB-S has
­established itself as the world's most
widely used satellite transmission standard. DVB-S/DSNG also uses 8PSK and
16QAM.
ISDB-C
ISDB-C is a Japanese cable standard
based on ITU-T J.83 Annex C. The DVB-C
coder in the ¸SFU supports all QAM
modulations defined in this standard.
J.83/B
J.83/B is an American cable transmission standard. The coder also supports the standard enhancement with
1024QAM.
T-DMB
DVB-S2
DVB-S2 is an innovative and efficient
channel coding method that is used in
combination with high-order modulation modes. The method is very robust,
offers safe reception and provides up
to 30 % higher data transmission rates
than DVB-S. The ¸SFU supports the
broadcast service mode for non-backwards-compatible broadcast services.
DIRECTV
DIRECTV (and DIRECTV legacy mode) is
a proprietary standard with conditional
­access that is widely used in America and
in the United States. For transmission,
a proprietary transport stream protocol
with 130-byte packets is generated. After
conversion to 188 bytes, ­DIRECTV transport streams can be replayed with the
¸SFU-K22 TRP ­player option.
¸SFU Broadcast Test System
Digital terrestrial TV standards
DVB-C
DVB-T
DVB-T permits high-quality transmission
of digital broadcast signals. Its success
will continue with the conversion from
analog to digital TV.
8VSB
ISDB-T
ISDB-T is a Japanese digital standard for
terrestrial transmission of video, audio,
and data signals by means of 13 segments. ISDB-T with partial reception is
for mobile operation.
ISDTV
ISDTV is the Brazilian digital standard
for the terrestrial transmission of video,
­audio, and data signals. It is based on
ARIB STD-B31 and thus corresponds to
ISDB-T as regards RF transmission.
J.83/B
DMB-T
DMB-T is a non-standardized multicarrier
transmission method developed for use
in China. It can be regarded as the predecessor of DTMB (GB 20600-2006).
ATSC/8VSB
8VSB is a terrestrial DTV standard from
the USA with vestigial sideband modulation. At a bandwidth of 6 MHz, a sideband is suppressed in the spectrum.
ATSC/A-VSB
A-VSB is another terrestrial DTV standard from the USA. It is based on 8VSB
and has been especially developed for
mobile reception.
Analog terrestrial television
standards
B/G, D/K, M/N, L and I
Analog standards with the B/G, D/K, M/
N, L, and I transmission systems as well
as the PAL, NTSC, and SECAM color systems are also available. Since the baseband signal has already been ­integrated,
an additional signal generator is not
­required.
ISDB-T
DVB-S2
DTMB (GB 20600-2006)
DTMB was developed in China and
has meanwhile become known as the
GB20600 standard. It offers high-­quality
digital TV with excellent characteristics,
based either on an OFDM or a singlecarrier transmission method.
¸SFU Broadcast Test System
Mobile TV standards –
video goes mobile
The following standards are ­terrestrial
transmission methods for broadcast
­applications with mobile receivers such
as mobile phones and PDAs.
DVB-H
The DVB-T/H coder provides the following functions: the newly introduced 4k
mode, use of the TPS carriers for time slicing signaling, the additional 5 MHz channel bandwidth and corresponding native
and in-depth symbol interleavers as well
as MPE forward error correction (FEC).
­Hierarchical coding is also possible.
T-DMB
T-DMB was developed in Korea and is
based on the digital audio broadcasting
(DAB) standard known in Europe, which
was also developed for mobile reception with radios. The T-DMB/DAB coder in the ¸SFU supports both the
­Korean and the European transmission
standards.
ISDB-T (partial reception)
With mobile ISDB-T in accordance with
ARIB 1.5, only one of altogether 13 available segments is used for transmission.
The remaining 12 segments can transmit
TV programs for stationary reception.
Testing mobile broadcast applications with the ¸SFU and the ¸CMU200
¸SFU Broadcast Test System
MediaFLO™
MediaFLO™ was developed and standardized by the American company
­QUALCOMM. The baseband signal in
this proprietary standard is based on a
transport stream with 188 bytes. MediaFLO™ is currently used in a nationwide
network in the USA. QPSK and 16QAM
methods are used as OFDM modulation
at a bandwidth of 5 MHz and 6 MHz. The
­data rates transmitted to the mobile receiver range ­between 50 kbit/s and 1
Mbit/s.
DMB-TH
DMB-TH is a modification and enhancement of the DMB-T standard initially
­developed. The DMB-H mode makes it
possible to use this modulation also for
handheld reception.
Terrestrial sound broadcasting
standards
DAB
Based on a COFDM transmission method, DAB was developed for digital and
high-quality audio transmission to
­mobile receivers.
ISDB-TSB
ISDB-TSB is a Japanese narrowband digital sound broadcasting standard for
the terrestrial transmission of audio
and ­data signals by means of one segment. ISDB-TSB is mostly used for ­mobile
­applications.
TS generator (¸SFU-K20)
A transport stream generator in the
baseband internally provides test
streams for the realtime coder. For
­external equipment, the test streams
are made available at an ASI output.
An ­external MPEG-2 generator is therefore no longer necessary. Furthermore,
the number of instruments needed for
testing set-top boxes is reduced and the
costs are minimized.
The transport stream generator allows
you to generate endless and seamless
high-bit-rate MPEG-2 transport streams
for the broadcast range. The SDTV transport stream library included as standard
contains ATSC and DVB test streams.
The numerous transport streams from
Rohde & Schwarz cover a wide range of
applications and test scenarios.

A large number of additional libraries
can be integrated. They make development faster and easier and allow new
products to be tested.

¸SFU Broadcast Test System
Stream generation tools
Stream generation tools provide full
flexibility when generating your own
streams, which can be used with
the ¸SFU-K20 TS generator. The
R&S®DV-ASC advanced stream combiner
allows you to generate your own transport streams, also for DVB-H.
TS recorder (¸SFU-K21)
A transport stream recorder and player as an expansion of the data source is
available for the ¸SFU. It allows you
to record any externally applied transport streams and ETI data streams at
­data rates between 100 kbit/s and up to
90 Mbit/s.
The available recording formats are TRP
with eight bits (8-bit data), T10 (10-bit
­data, 1-bit data valid, 1-bit packet sync),
and ETI. With the 8-bit and T10 formats,
the parallel SPI (LVDS) interface is used.
The ¸SFU-B11 ETI interface (optional) is required for the ETI format.
¸DV-ASC advanced stream combiner
The amount of data that can be recorded
is limited only by the size of the hard disk.
The recorded transport streams can be
transferred to other storage media via the
USB or LAN interface. Using the TS recorder, the streams can be replayed endlessly and seamlessly with packet-exact
cutting at the end-of-file/start-of-file transition.
To enable R&S®SFU-K21, you require the
R&S®SFU-B6 ­additional hard disk, the
R&S®SFU-B4 memory ­extension 2, and
the R&S®SFU-K22 TRP player.

TRP player (¸SFU-K22)
Arbitrary waveform generator
The TRP player lets you replay your own
transport streams in TRP format. The
transport streams can be copied via the
USB or LAN interface to the ¸SFU
file system and be replayed from there.
The integrated arbitrary waveform (ARB)
generator of the R&S®SFU opens up a
wide range of additional applications,
such as simulating occupied adjacent
channels, adding interferers to the useful signal, and generating user-defined
RF signals (e.g. notched noise).
In addition, this TRP player is used to replay T-DMB and DAB ETI streams. For
this purpose, the TRP player can replay
predefined ETI test streams for T-DMB
and DAB from an optional T-DMB/DAB
library (¸SFU-K221).
To enable the ¸SFU-K22 TRP ­player
option, the ¸SFU-B6 additional
hard disk and the ¸SFU-B4 memory
­extension 2 are required.
It is thus possible to generate any externally computed complex modulation
­signals. A hardware resampler and a low
oversampling rate significantly reduce
the memory space needed to store I/Q
waveforms on the hard disk. This allows
you to store a large number of I/Q waveforms directly on the hard disk.
Video/audio generator
(¸SFU-K23)
Together with the analog realtime coders, the video/audio generator offers a
complete solution for modulated analog
and interruption-free video test patterns
and audio signals. The video/audio generator is generally available with every
analog realtime coder.
In addition to the PAL, NTSC, and
­SECAM test patterns included in the
­basic configuration, an ATV-Video library
with comprehensive analog video test
signals can be integrated.

¸SFU Broadcast Test System
Externally generated I/Q waveform files
can also be loaded into the instrument
and read out via one of the computer
­interfaces such as USB or LAN, or via the
IEC/IEEE bus.
Together with the ¸SFU-K81 option,
which switches off the realtime coder
function, the ARB generator can also be
used for easy, cost-efficient production
solutions. If a wider scope of functions is
required, the realtime coders ­integrated
in the ¸SFU can subsequently be enabled by means of keycode options (see
figure on page 12).
Waveform libraries
Additional waveform libraries allow
quick evaluation of new modulations. I/Q
waveform libraries are available for the
following signals:
T-DMB/DAB (R&S®SFU-K351)
DVB-H (R&S®SFU-K352)

BER measurement
The BER measurement, which operates
independently of other applications, is
used to check channel conditions. The
integrated BER tester allows you to evaluate a signal demodulated and decoded
by the DUT by means of the BER measurement. Two general methods are
available for this purpose.
A measurement with a pure pseudo-random binary sequence (PRBS) can check
the demodulation section of the ­receiver.
A known PRBS-modulated data sequence
is sent to the DUT, which decodes the signal and feeds the ­decoded data and the
associated clock back to the ¸SFU.
If the error ratio of the decoding branch
must also be measured, the MPEG-2 TS
can be returned. In this case, the test
signal includes an MPEG-2 TS that contains a PRBS as payload. If path measurements on a live MPEG-2 signal are to be
performed, the null packets must contain
a PRBS payload. The BER tester of the
¸SFU synchronizes to the returned,
known PRBS and counts the bit errors.
The quotient obtained by dividing the
number of ­error bits by the total number
of bits is the BER.

You can easily switch operating parameters (e.g. roll-off, puncturing rate, QAM
mode) and select operating parameters
whose values exceed those defined in
the standard for lab applications. Nonideal behavior of the I/Q modulator can
be simulated by selectively changing
amplitude, phase, and carrier leakage
before the signal enters the I/Q modulator.

AWGN generator
(¸SFU-K40)
The digital additive white Gaussian noise
(AWGN) generator is used as a source
for generating a pure noise signal modulated onto the carrier and for influencing
the actual useful signal. Realistic noise
can be simulated in the transmission
path – via satellite, cable or ­antenna
– by generating a 96 MHz broadband
­AWGN signal with a Gaussian amplitude
distribution in the digital baseband.
The AWGN generator can be used if the
R&S®SFU-K40 software option has been
enabled.
Phase noise (¸SFU-K41)
The phase noise of the ¸SFU
synthesizer is typically less than
–135 dBc/Hz (1 GHz, 20 kHz offset). The
¸SFU is therefore ideal for simulating phase noise. The option allows you
to simulate phase noise in oscillators and
phase lock loops. In the setting range from
­–10 dBc/Hz to –110 dBc/Hz, the wanted
phase noise can be loaded as a profile. User-defined profiles can be generated with
conventional simulation programs such as
­MATLAB®, ported as a file to the ¸SFU
by means of a USB stick, and stored on
the hard disk. The phase noise functionality can be used if the ¸SFU-K41 software option has been enabled.

¸SFU Broadcast Test System
Impulsive noise
(¸SFU-K42)
Impulsive noise permits the pulsed addition of an AWGN signal to the useful signal with a settable number of ­pulses.
I­mplementation is in line with DTG,
Dbook, and A/74 with a maximum bandwidth of 96 MHz. In addition, the statistical distribution of the pulse intervals can
be selected.
The pulse generator required for the pulses is integrated in the ¸SFU. An additional external signal generator and
the associated cabling are thus no longer
necessary. The pulse spacing limits, the
number of pulses, and the burst duration
can be configured very easily.
The impulsive noise functionality can be
used if the ¸SFU-K42 software option
has been enabled.
Multinoise use
(¸SFU-K43)
Impulsive noise with DVB-T
The multinoise use functionality can be
used if the ¸SFU-K43 software option
has been enabled.
It permits the simultaneous use of multiple noise sources in the form of an additive noise signal which, in turn, can be
added to the useful signal.

Fading simulator
(¸SFU-B30/¸SFU-B31)
The channel simulator (fading simulator)
of the ¸SFU is ideal for realtime simulation of multipath and mobile reception. The basic version (¸SFU-B30)
provides up to 20 paths; with the full
version (¸SFU-B31), up to 40 paths
are available.
Profiles
The fading simulator supports profiles
in accordance with DVB, ATTC, and
­MediaFLO™. Several fading profiles per
path can be selected and simulated. You
may choose from the following profiles:

You can vary all fading parameters such
as attenuation, phase, delay and Doppler, speed and direction.
DAB with Gaussian fading
The Gaussian fading (¸SFU-K32)
used for DAB and for the Korean T-DMB
mobile standard is included in the realtime T-DMB/DAB coder (¸SFU-K11)
and in the T-DMB/DAB waveforms option (¸SFU-K351), respectively, and
permits the corresponding channel
simulations.

Enhanced fading
(¸SFU-K30)
The moving propagation and birth-death
dynamic fading configurations can be
used to increase the resolution of the

propagation conditions as well as fine
delay configurations. These configurations are provided by the enhanced fading option.
Dynamic fading with moving propagation
The enhanced fading functionality can be
used if the R&S®SFU-K30 software option
has been enabled. It requires an installed
R&S®SFU-B30 option (or R&S®SFU-B30
and R&S®SFU-B31).

Diversity simulation
When testing diversity receivers, a separate RF receive signal must be provided for each antenna of the ­receiver.
The ­receive signals must have the same
baseband signal and the RF signal must
be coupled. The noise and fading signals, however, must show no correlation; this is only possible with one
¸SFU per antenna.

Interferers
Interferers can be added to the useful ­signals at different points along
the transmission path. When adding
the ­interferers, the level can be varied within a wide range. The maximum
­frequency shift to the useful signal can
be ±40 MHz.
Transmission simulations can be used
for the mixed signals. The R&S®SFU can
simulate the impairment of the useful
signal by interferers very compactly and
without requiring any external ­signal
sources.
±40 MHz
In addition to the signals and signal libraries already available from
­Rohde & Schwarz (such as the multi ATV
predefined option with analog TV signals), you can define other interferers
by means of the R&S® WinIQSIM™ software and use them on the ¸SFU.
Interferer libraries
±40 MHz
The following signal libraries are available as options for analog and digital ­interferer scenarios in line with
IEC 62002 (MBRAI), NORDIG, and A/74:
Useful signal with analog (top) and digital interferer
◆ ¸SFU-K199, multi ATV
­predefined, analog interferers
◆ ¸SFU-K354, DTV interferers,
­digital interferers
For complex cable interferer scenarios, a
collection of diverse test functionalities
based on SCTE 40 is made available as a
library in the following option:
◆ ¸SFU-K356, cable interferers

Interferer management
LAN
GPIB
The ¸SFU-K37 option permits easy
and straightforward interferer management. Level, frequency, frequency offset,
and signal type can be set.
Internal interferers
The ¸SFU-K199/-K354/-K356
­interferer ­libraries/signals or any other
ARB I/Q signal can be used as internal
interferers.
External interferers
External interferers can be applied via
the ¸SFU‑K80 analog or digital I/Q
interface while ARB sequences or analog TV signals can be provided internally.
USB interfaces on the front panel
Connectivity
LAN (100BaseT), GPIB, and a USB connector are available as interfaces on
the instrument's rear panel. Files, firmware updates, and modulation data can
be loaded fast and easily via these interfaces.
GPIB/IEEE
LAN/Ethernet
Possible remote control variants with the ¸SFU
Remote operation and remote
­control
The ¸SFU can be remote-operated
via an Ethernet connection or in a LAN
network over IP and is preconfigured
for DHCP use. The preinstalled Remote
Desktop software or the VNC software
that comes with the instrument makes
this very easy to do.
Remote control is possible by means of
control commands via the IEC/IEEE bus
(GPIB) or LAN. The ¸SFU can thus
be integrated into existing test programs
and remote-controlled.
The compatibility of the ¸SFU
­remote control commands with the
¸SFE family ensures easy porting of
the remote control programs. Programs
generated for the ¸SFU can thus be
used in the lab or in production without
any loss of time, since time- and cost­intensive verification tests do not have to
be performed.
Looking forward
The ¸SFU's modular design makes it
a future-proof investment. Options can
usually be activated quickly and conveniently on-site at any time by means of
firmware update and license code.
This feature ensures fast and easy availability without time loss and is a big advantage for use in production and development. The ¸SFU can be adapted
to perfectly match current requirements,
and its configuration can be tailored to
meet customer-specific needs. It thus
saves a lot of money yet offers full flexibility and openness for new, evolving
fields of application.
