HIGH DATA RATE RECEIVER
HDR-4G+ USER'S MANUAL
Telemetry bit rate. Expressed in bps. Enter any value from 1e6 to the maximum
admissible bit rate (license, modulation and firmware are menu dependent)
Important: if the data are convolutionally encoded, enter the bit rate at the Viterbi
decoder input (bit synchronizer output).
In DVB-S2, SCCC and VCM modes, the Bit Rate is replaced by the Symbol Rate
Telemetry PCM coding technique: NRZ-L/M/S, DNRZ, Bi-P-L/M/S, NRZ-M Merge
Important: if NRZ-M Merge is selected, the NRZ-M to NRZ-L decoding is performed
after the merging of the data coming from I and Q. If NRZ-M is selected the decoding
is performed separately on I and Q before data merging.
Auto-synchronized de-scrambler:
 Disable
 Worldview
 CCITT V.35
 Intelsat V.35
For QPSK, 16QAM and n-APSK modulations:
 Normal
 I Inverted
 Q Inverted
 I/Q Inverted
 Swap Normal
 Swap I Inv.
 Swap Q Inv.
 Swap I/Q Inv.
 Ambig DPUA (B) Ambiguity resolution by DPU A (B)
 Ambig DPUC (D) Ambiguity resolution by DPU C (D)
 Ambig DPUA+C (B+D) Ambiguity resolution by DPU A&C (B&D)
 Ambig BER
 Ambig 4DPU
16)
 Ambig 8DPU
16)
For 8PSK modulation:
 Normal
 Rot 45°
 Rot 90°
 Rot 135°
 Rot 180°
 Rot 225°
It cannot be duplicated or distributed without expressed written consent.
