DNRZ PCM Decoding (deprecated) 4.2.9.2.6
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
OQPSK (SQPSK) Algorithm 4.2.9.2.7
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.
DVB-S2 randomization polynomial 4.2.9.2.8
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.
Transport Layer: Frame Synchronizer Setting 4.2.9.3
Check to Lock Strategy (CTL) for RS DVB 4.2.9.3.1
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.
