Operating instructions

DMD50 Universal Satellite Modem User Interfaces
TM118 – Rev. 1.1 4-7
COMPENSATION {0.0 – 1.0}
Allows you to offset output power by up to 1 dbm. This
is intended as a correction for user cabinet connectors.
DATA (menu)
DATA RATE (bps) {Refer to Technical Specs for Data Rates}
Allows the user to set the Data Rate in bps steps via the
Front Panel Arrows or Keypad.
SYMB RATE (sps) Allows the user to view the Symbol Rate.
INNER FEC Viterbi {1/2, 3/4, 7/8, None}
Optional FEC Rates:
Sequential {1/2, 3/4, 7/8}
Trellis 8PSK {2/3}
Turbo ≤ 20Mbps {.793, .495, 1/2, 3/4, 7/8}
Turbo >20Mbps {.750, .875}
Comstream Seq {3/4}
DVB VIT {1/2, 2/3, 3/4, 5/6, 7/8}
DVB Trellis {2/3, 5/6, 8/9}
Allows the user to select the Rx Code Rate and Type
TPC INTERLEAVER {DISABLE, ENABLE}
Allows user to disable or enable the TPC Interleaver.
Valid only for Radyne turbo codes TPC.495 and
TPC.793
DIFF CODING {ENABLED, DISABLE}
Allows the user to enable or disable the Differential
Encoder. Having the encoder enabled ensures proper
phase lock. May not be adjustable in some modes.
SCRAMBLER SEL {NONE, V.35-IESS, V.35 CITT, V.35 EF, IBS
w/Optional Framing and optional Reed-Solomon,
Reed-Solomon Scrambler w/Optional Framing,
CCITT, V.35FC, OM-73, V.35EF_RS, TPC
SCRAMBLER (Turbo Codec), DVB, EDMAC}
Allows the user to select the descrambler type.
SCRAMBLER CTRL {ENABLED, DISABLE}
Allows the user to enable or disable scrambler operation.
SAT FRAMING {1/15 (IBS), 1/15 (Async), 96 Kbps (IDR), DVB,
EDMAC, EFAUPC, SCC, EFFICIENT D&I, None}
Used with IDR, IBS, or Asynchronous Interface Only.
Allows the user to select the framing type.
IN-BAND RATE {150, 300, 600, 1200, 2400, 4800, 9600, 19200}
Allows the user to select the rate of in-band data for the
ES to ES, Async overhead channel.
Only displayed when Effiecient D&I with Enhanced
Async are selected.
