Rev. 6 B–19
B.1.4.1.3 Demodulator/Decoder Configuration Status
The Demodulator/Decoder configuration status command causes a block of data to be
returned by the addressed modem. The block of data reflects the current configuration of
the demod.
Command: <add/DCS_”cr”
Response: >add/DCS_”cr”
DF_nnn.nnnn”cr” Demodulator Frequency
DR_nnn_mmmm.m”cr” Demodulator Data Rate
ADRA_nnn_mmmm.m”cr” Filter “A” Assignment
ADRB_nnn_mmmm.m”cr” Filter “B” Assignment
ADRC_nnn_mmmm.m”cr” Filter “C” Assignment
ADRD_nnn_mmmm.m”cr” Filter “D” Assignment
DE_xxx”cr” Descrambler Enable (ON/OFF)

BBL_xxx”cr” Baseband Loopback (ON/OFF)
RFL_xxx”cr” RF Loopback (ON/OFF)
BERT_xxxx”cr” BER Threshold
SR_xxx”cr” Sweep Reacquisition (seconds)
IFL_xxx”cr” IF Loopback (ON/OFF)
(See Note 1) SCF_snnnnn”cr” Sweep Center Frequency
(See Note 1) SWR_nnnnn”cr” Sweep Width
(See Note 1) SD_s”cr” Sweep Direction
FAM_xxx”cr” Fast Acquisition Mode
(See Note 2) BC_xxx”cr” Buffer Clock Source
(See Note 2) IBS_nnnnn”cr” Interface Buffer Size
ADRV_nnn.mmmm.m”cr””lf”] Demodulator Variable Rate Assignment

Notes:
1. “SCF_”, “SWR_”, and “SD_” responses are returned only when fast acquisition
is enabled. See the “FAM_” command definition.
2. “BC_” and “IBS_” responses are returned only when Buffer Control is enabled.
See the “BUFF_” command definition.
