1 Welcome to the DVB options
The R&S SMW-K52/-K116 are firmware applications that add functionality to generate
signals in accordance with:
●The DVB-H/T (Digital Video Broadcasting - Transmission System for Handheld Ter-
minals) standard
●The standards describing the second-generation DVB system for satellite commu-
nication DVB-S2 and the optional extension DVB-S2X.
DVB (digital video broadcasting) provides a communications infrastructure for powerful
transmission of MPEG-2-based data. Besides satellite-based (DVB-S), terrestrial
(DVB-T) and cable-bound (DVB-C) transmission schemes, the version (DVB-H) is for
portable/handheld terminals.
DVB-H is an extension to DVB and is compatible with the basic concept of the stan-
dard. The extensions bring advantages that are especially important for portable devi-
ces: low power consumption, small hardware and robustness against fading effects.
For DVB-H the current firmware supports non-hierarchical coding only.
The DVB-S2 standard is introduced as successor the DVB-S for the transmission of
digital video broadcasts over satellite links. The DVB-S2X standard is an optional
extension of the DVB-S2 standard. DVB-S2X allows an efficiency gain of up to 51%
compared to DVB-S2. With that, higher data rates can be transported over the same
satellite transponder capacity.
The main advantages of the DVB-H / DVB-T digital standard option R&S SMW-K52
are:
●Possibility to test both mobile communications standards (such as WCDMA 3GPP
FDD, TD-SCDMA, GSM/EDGE) and DVB-H or DVB-T using only one signal gener-
ator
●Simple generation of standard-compliant DVB-H or DVB-T signals
Option R&S SMW-K116 extends the functionalities with the following key features:
●Fully encoded DVB-S2 and DVB-S2X signal generation
●Support of the stream types: transport stream (TS), generic packetized (GP),
generic continuos (GC), generic stream encapsulated high efficiency mode (GSE-
HEM)
●Signal generation form arbitrary data sources and TS or GSE files
●Channel coding according to the standard, incl. scrambling, interleaving, outer
code (BCH), inner code (LDPC) with varying code rates from 1/4 to 31/45
●Support of all specified Walsh-Hadamard sequences for VL-SNR (very low signal
to noise ratio) mode
●Configurable header information, incl. baseband (BB) header, VL-SNR header, TS
header, GSE header
●Supported modulation schemes:
– For DVB-S2: QPSK, 8PSK, 16APSK, 32APSK
– For DVB-S2X: QPSK, 8APSK, 8PSK, 16APSK, 32APSK, 64APSK, 128APSK,
256APSK

2 About the DVB options
The digital video broadcasting (DVB) suite of standards described methods for data
and video signals transmission through different medium including cable, terrestrial,
mobile and satellite.
This section lists required options and provides brief background information on basic
terms and principles used in the DVB standards.
2.1 Required options
The basic equipment layout for generating DVB signals includes the:
●Standard or wideband Baseband Generator (R&S SMW-B10/-B9)
●Baseband main module (R&S SMW-B13) or wideband baseband main module
(R&S SMW-B13XT)
●Frequency option (e.g. R&S SMW-B1003)
●Digital standard DVB-H / DVB-T (R&S SMW-K52)
●Digital standard DVB-S2 / DVB-S2X (R&S SMW-K116)
You can generate signals via play-back of waveform files at the signal generator. To
create the waveform file using R&S WinIQSIM2, you do not need a specific option.
To play back the waveform file at the signal generator, you have two options:
●Install the R&S WinIQSIM2 option of the digital standard, e.g. R&S SMW-K255 for
playing LTE waveforms
●If supported, install the real-time option of the digital standard, e.g. R&S SMW-K55
for playing LTE waveforms
For more information, see data sheet.
2.2 About DVB-H/T
The Digital Video Broadcasting - Handheld (DVB-H) standard is based on the earlier
standard DVB-T, which is used for terrestrial digital broadcasting.
The block diagram on Figure 2-1 shows the components of the DVB-H transmission
system.

Figure 2-1: Components of the transmission system DVB-H
The current firmware does not support hierarchical coding including low-priority coding.
The Low-Priority (LP) path of the MPEG-2 Stream indicates this by dotted squares of
the low-priority coding procedure.
DVB-H provides features to meet the specific requirements for handheld, mobile termi-
nals such as:
●Power off some part of the reception chain to increase the battery duration
●Ease access to the services when receivers switching to the next cell
●Mitigate the effects of man-maid noise and severe mobile multipath channels on
the receiving capabilities
●Offer sufficient flexibility and scalability to allow reception of services at various
speeds
●Offer the flexibility to be used in various transmission bands and channel band-
widths
The basic technical extensions that make it possible to receive digital video broadcast-
ing services on handheld terminals are:
●4K mode and in-depth interleavers
●Time-slicing
●Forward error correction for multiprotocol encapsulated data (MPE-FEC)
2.3 About DVB-S2/S2X
Figure 2-2 illustrates schematically the components of the DVB-S2/S2X transmission
systems. The block diagram is a simplified version of the DVB-S2 system specified in
the DVB standard.

Figure 2-2: Components of the transmission system DVB-S2/S2X
FEC = Forward error correction
BCH = Bose-Chaudhuri-Hocquenghem multiple error correction binary block codes
LDPC = Low-density parity check
The main improvements of the second-generation DVB system for satellites (DVB-S2)
compared to DVB-S are:
●Input stream adapter, suitable for operation with single and multiple input streams
and different formats (packetized or continuous)
●FEC system based on LDPC codes concatenated with BCH codes
●Range of code rates (from 1/4 up to 9/10);
Four constellations with different spectrum efficiency and optimized for operation
over non-linear transponders
●Three predefined spectrum shapes with rolloff factors 0.35, 0.25 and 0.20
●Adaptive coding and modulation (ACM) functionality for optimized channel coding
and modulation on a frame-by-frame basis.
The DVB-S2X is an extension to the DVB-S2 standard. The DVB-S2X reuses the DVB-
S2 system architecture and improves it with the following:
●Adds finer MODCOD steps, higher-order modulations and complex constellations
●Three new sharper spectrum shapes
●Defines the VL-SNR (low signal to noise ratio) mode for example for mobile appli-
cations
●Optional periodic pilots and physical layer scrambles for easy synchronization
●GSE-Lite compliant signaling and streaming
●Adds a high-efficiency mode (GSE-HEM) intended to transport GSE and GSE-Lite
packets

Inner Interleaver Mode
Selects the inner interleaver mode. Interleaver mode in-depth is available only for
transmission mode 2K and 4K.
"Native" Available for all transmission modes ("Tx Mode").
"In-depth" Requires "Tx Mode > 2K/4K".

Inner Interleaver Tx Mode
Selects the transmission mode.
The transmission mode determines the number of the OFDM subcarriers.
For "Tx Mode > 8 K", the in-depth interleaver mode is not available. "Tx Mode > 4 K" is
available only for "Standard > DVB-H".

Cell Identification
Activates TPS cell identification. If activated, the cell from which the signal comes from
is identified.
Remote command:
[:SOURce<hw>]:BB:DVB:DVBH|DVBT:TPS:ID:STATe on page 91
ID (hex)
Sets the cell ID for cell identification.
The cell ID identifies the cell from which the signal is transmitted. This value is read by
the receiver if Cell Identification is activated.
