Dnrz Pcm Decoding (Deprecated); Oqpsk (Sqpsk) Algorithm; Dvb-S2 Randomization Polynomial; Transport Layer: Frame Synchronizer Setting - Safran CORTEX Series User Manual

4.2.9.2.6

DNRZ PCM Decoding (deprecated)

Selecting the DNRZ code in QPSK and OQPSK demodulation mode:
Registry path: HKEY_LOCAL_MACHINE/SOFTWARE/In-Snec/CrtxHdr/SetDefault/Signal
Processing /Dmu#n
Keyword:
DNRZ_code
Default setting: 0
4.2.9.2.7

OQPSK (SQPSK) Algorithm

OQPSK demodulation algorithm definition
Registry path: HKEY_LOCAL_MACHINE/SOFTWARE/In-Snec/CrtxHdr/SetDefault/Signal
Processing /Dmu#n
Keyword:
Algo_OQPSK
Enter 0 for standard algorithm and 1 for enhanced algorithm (better resistance to pattern, but higher
synchronization threshold).
Default setting: 0.
4.2.9.2.8

DVB-S2 randomization polynomial

Selection of the randomization polynomial for DVB-S2 standard
Registry path: HKEY_LOCAL_MACHINE/SOFTWARE/In-Snec/CrtxHdr/SetDefault/Signal
Processing /Dmu#n
Keyword:
DVBS2_PIScrambling_Num
Enter 0 to 262141 (refer to the DVBS2 standard, document EN 302307 V1.1.1 § 5.55.4)
Default setting: 0.
4.2.9.3

Transport Layer: Frame Synchronizer Setting

4.2.9.3.1

Check to Lock Strategy (CTL) for RS DVB

Registry path: HKEY_LOCAL_MACHINE/SOFTWARE/InSnec/CrtxHdr/SetDefault/Signal
Processing/Dpu#n
Keyword:
RSDVB_Ctl
Enter an integer value between 0 and 10.
Default setting: 2.
