2 About the DVB-S2x Option
DVB-S2 is the second-generation DVB standards for satellite services. It has evolved
from DVB-S. Comparing DVB-S2 with DVB-S at the same transponder bandwidth and
EIRP shows the following. By using innovative and more efficient channel coding meth-
ods, combined with higher-order modulation modes, 30 % more data can be transmit-
ted with DVB-S2.
DVB-S2 complies with specification EN 302 307.
2.1 Required Options
The equipment layout for generating DVB-S2x signals includes:
●Base unit
●Option Enable Broadcast Standard (R&S SMCVB-K519)
●Option DVB-S / DVB-S2 (R&S SMCVB-K167)

"ACM" Variable coding and modulation. Changes of settings are executed
seamlessly at the end of a complete PL frame.
"VCM" Enables multiple input streams (MIS).
Depending on the Num. Input Streams, you can set the input signal
parameters individually for 2 input streams. For all other input
streams, test TS packets are used. All input streams are using differ-
ent PIDs for the TS test packets.
Thus, you can perform a BER measurement on every input stream, if
the PID filter of the BER measurement is enabled. For input stream 1,
set the PID of the TS test packets, see " PID (Hex) " on page 21.
For all subsequent input streams, the PID is derived from its prede-
cessor by subtracting 1.
Example:
For input stream 1, set "PID > 1FFF" (0x1FFF). The PIDs of the other
input streams (IS) are as follows: IS2: 0x1FFE, IS3: 0x1FFD,
IS4: 0x1FFC, IS5: 0x1FFB, IS6: 0x1FFA, IS7: 0x1FF9, IS8: 0x1FF8.
After completing one BB frame, the next input stream is used to fill
one BB frame.
If necessary, padding is performed to complete the BB frame. A new
BB frame uses the next input stream. After the last input stream, a
new merger cycle starts, and the next BB frame uses input stream 1.
Remote command:
[:SOURce<hw>]:BB:DVBS2[:INPut]:CMMode on page 61
Annex M
Enables the annex M features as specified in EN 302 307. Depending on this setting, a
different PL header is used.

"Off" No time-slicing.
Remote command:
[:SOURce<hw>]:BB:DVBS2:ANNM on page 69
S2-X
Enables S2-X features.
For DVB-S2-X, additional modulation coding settings are defined to obtain a finer SNR
granularity compared to classical S2 modulation coding:
●Clear sky conditions (e.g. 256 APSK)
●Linear channel models (marked with"-L")
●Very low SNR conditions (VL-SNR)
●...
Related to a DVB-S2-X modulation coding setting is a corresponding LDPC code rate
and a FEC frame type. If the order of the modulation coding is higher than QPSK, a bit
interleaver pattern is related to this modulation coding setting.
Note: VL-SNR modulation coding, super frame and channel bonding are released in a
later version.
