InitTerm_F

- Termination Sequence After Flush Operation

Sequence after flush operation for termination of Viterbi decoder. The upper 8 bits have to be the PRC preamble

1D(hex) in ascending order (b12..b19).

VitBerCtrl_F

- Viterbi BER Measurements Control

b3 :

fvd_csat_ber_mode ‘0’= Sat. measurment as single acquisition

‘1’= Sat. measurement as continuous acquisition

b2 :

fvd_csat_ber_en

‘0’= Sat. BER measurement disabled

‘1’= Sat BER measurement enabled

b1 :

fvd_terr_ber_mode ‘0’= Terr. measurment as single acquisition

‘1’= Terr. measurement as continuous acquisition

b0 :

fvd_terr_ber_en

‘0’= Terr. BER measurement disabled

‘1’= Terr. BER measurement enabled

TerrBer_F

- Terrestrial Channel Bit Error Rate

The terrestrial channel error rate states the number of channel symbol errors which where determined within

one PRC packet by reencoding of the Viterbi-decoded terrestrial data stream. A new measurement is indicated

by the signal terr_ber_done which is comprised in the interrupt vector (addr. 0x0350)

Sat1Ber_F

- Satellite 1 Channel Bit Error Rate

The Sat1 channel error rate states the number of channel symbol errors which where determined within one

PRC packet by reencoding of the Viterbi-decoded Sat1 data stream. A new measurement is indicated by the
