Front view of the ¸SFE100
The R&S®SFE100 is a single-standard
test transmitter with realtime coding for
broadcast signals. R&S®SFE100 models
are available for all common TV standards and a number of sound broadcasting standards.
The R&S®SFE100 is a compact and reliable instrument that can be equipped
with a power amplifier unique in this
class, making it particularly valuable in
production test systems. Plus, it can be
used as a simple and economical signal
generator as well as for special applications as a second RF channel for the
R&S®SFU.
Every R&S®SFE100 model can be
equipped with the appropriate digital
or analog baseband signal source with
which test signals from Rohde & Schwarz
libraries or customer-specific test signals
can be replayed.
The R&S®SFE100 thus combines two
functions in one box, thereby significantly simplifying complex production
test systems.
The R&S®SFE100 model with an arbitrary
waveform generator enables you to generate modulation signals of any type and
to replay customer-specific waveform
files, irrespective of the available realtime coder models.
Occupying only one height unit, the
R&S®SFE100 is extremely compact.
Nevertheless, all functions can be
selected locally on the instrument.
Alternatively, the R&S®SFE100 can be
remote-operated from a PC. In this case,
operation is performed using the same
convenient graphical user interface as
for the R&S®SFE and R&S®SFU.

Single-standard signal
generator with realtime coding
The R&S®SFE100 is a single-standard
instrument specially designed for use
in production. Realtime coding offers a
number of advantages in this area as
well. Realtime coders generate endless
and seamless test signals. Therefore,
the signal generators do not need to be
synchronized with the production cycle.
Moreover, very long sequences can be
replayed and the modulation parameters
can be set as required.
Coder for realtime signal generation ◆
The R&S®SFE100 has a powerful
hardware platform for baseband signal processing. The platform provides
the I and Q bit streams for the broadband vector modulator. It is factoryconfigured for the specific transmission standard required
Adjustable modulation parameters ◆
With each transmission standard,
various modulation parameters such
as constellation, code rate, and FFT
mode must be defined. These parameters can be varied irrespective of the
transport stream or A/V signal to be
transmitted. All conceivable versions
of a standard can thus be tested. The
realtime coder automatically adjusts
the corresponding signaling information for the receiver
Models for all common digital
and analog broadcasting
standards
As a single-standard instrument, the
R&S®SFE100 comes with a factory installed coder. R&S®SFE100 models are
available for all major standards and
technologies. For signal generation
systems in production, this is a major
advantage: No matter whether digital or
analog receivers or terrestrial, satellite,
or cable set-top boxes are being manufactured, all test signals can be generated with the same type of test transmitter.
The R&S®SFE100 is available for the
following standards:
Terrestrial digital TV: DVB-T, DTMB, ◆
ATSC/8VSB, ISDB-T, ISDB-T
Cable TV: DVB-C, J.83/B, ISDB-C ◆
Satellite TV: DVB-S/DSNG, DVB-S2, ◆
DirecTV
Mobile TV: DVB-H, T-DMB, ISDB-T ◆
1-segment, MediaFLO™, ATSC/AVSB,
DMB-TH
Analog TV: B/G, D/K, I, M/N, L ◆
Sound broadcasting: DAB, ISDB-Tsb, ◆

Wide frequency range with very
good signal quality
The instrument‘s RF characteristics
make it clear that the R&S®SFE100 is a
high-quality signal generator despite its
compact design and economical price. It
covers the entire frequency range that is
relevant for broadcast applications, from
IF, VHF, and UHF up to the L band. And
it does so with a signal quality that is
unprecedented in this class.
Frequency range 100 kHz to 2.5 GHz ◆
The frequency can be adjusted in
steps of 1 Hz. Either the center frequency or the channel number is entered, which is especially useful in
analog TV
Low phase noise and high MER ◆
Advanced COFDM modulation
methods place high requirements
on the stability and spectral purity
of the oscillator signal. With an SSB
phase noise of <–115 dBc (typ. at
300 MHz and 20 kHz carrier offset),
very high MER values of over 40 dB
(typ.) are attained. Furthermore, the
R&S®SFE100 stands out due to its low
wideband noise and good harmonics
suppression
