Punctured Viterbi Setting 4.2.9.2.2
Setting of the punctured codes and swap function:
Registry path: HKEY_LOCAL_MACHINE/SOFTWARE/InSnec/CrtxHdr/SetDefault/Preferences/
Dmu#n
Keywords: ViterbiPunctCode0, ViterbiPunctCode1 and ViterbiPunctSwapp
For Code 0 and code 1: enter 0 for no puncturing and 1 for punctured Viterbi. Enter 0 for swap OFF, 1
for swap ON convention 1 and 2 for swap ON convention 2.
Default setting: 0.
BER on Merged or Separate I/Q 4.2.9.2.3
Selecting the BER measurement technique in PRN BER mode (see 3.3.8 ) and BER display on the
GUI:
Registry path: HKEY_LOCAL_MACHINE/SOFTWARE/In-Snec/CrtxHdr/SetDefault/Signal
Processing /Dmu#n
Keyword: BerIQ
Enter 0 for one BER value on merged I & Q (using method 1).
Enter 1 for two BER values (on I & on Q) (using method 1).
Enter 2 for one BER value on merged I & Q (using method 2).
Default setting: 0.
High EbNo Tracking Mode 4.2.9.2.4
This key describes the mode of tracking of the high EbNo:
Registry path: HKEY_LOCAL_MACHINE/SOFTWARE/In-Snec/CrtxHdr/SetDefault/Signal
Processing /Dmu#n
Keyword: TrackBERHigh
Default setting: Enter 0 for EbNo computed from the I/Q constellation. Enter1 for high EbNo (> 12 dB)
update from IF level measurements (assuming the noise level is constant).
I/Q Synchronization in Capture Mode (menu # 7) 4.2.9.2.5
Expected timing for external I/Q input signals (external I/Q data recovery mode):
Registry path: HKEY_LOCAL_MACHINE/SOFTWARE/In-Snec/CrtxHdr/SetDefault/Signal
Processing /Dmu#n
Keyword: BitSyncMode_IQ_sync
Enter 0 for synchronized I/Q and 1 for Q data timing delayed by ½ symbol compared to I data.
Default setting: 0
