Bit Synchronizer Mode; Removal Of The R-S Codeblock And Synchronization Word; Removal Of The Synchronization Word For Frame Checking; Removal Of Dummy Frames For Tm Storage - Safran CORTEX CRT Quantum User Manual

4.2.7.3.3. Bit Synchronizer Mode

The Bit Synchronizer can be programmed to operate either in the standard mode (standard Bit Synchronizer) or
the extended mode (phase-locked to the BPSK sub-carrier). The extended mode is available for low bandwidth
applications with the Viterbi license only:
Registry path:
Keyword:
Default setting at delivery:
Enter 0 (standard mode) or 1 (Bit synchronizer phase-locked to the BPSK sub-carrier).

4.2.7.3.4. Removal of the R-S Codeblock and Synchronization Word

To customize the telemetry message (Annex 1, STI 100013_CRT, section 2.4.4) with the R-S decoding license:
Registry path:
Keyword:
Default setting at delivery:
Set bit 0 to 0 for transmitting the R-S code and the SW or 1 for removing the R-S code and the SW.
Set bit 1 to 0 for standard Frame Check result field (offset 6) or to 1 for reporting the number of errors corrected
by the R-S decoder in byte 1 of the Frame Check Result field

4.2.7.3.5. Removal of the Synchronization Word for Frame Checking

To include or exclude the synchronization word for CRC or Check Sum verification
Registry path:
Keyword:
Default setting at delivery:
Set the keyword to 0 (SW included) or 1 (SW excluded)

4.2.7.3.6. Removal of Dummy Frames for TM Storage

To remove or not the dummy frames in telemetry data storage files
Registry path:
Keyword:
Default setting at delivery:
Set the keyword to 0 (Dummy frames stored) or 1 (dummy frames not stored)
