MS-4900, Rev. A A-1
Appendix A. Technical Specifications
IDR V1000
The following specifications relate to the receiver’s functional characteristics and
its external and environmental characteristics.
RF input level -85 dBm to -40 dBm
RF input frequency 950 MHz to 1,525 MHz
RF tuning Synthesized, front panel selectable in 50 kHz steps. Receiver
uses local scan, and locks to a valid carrier between step
sizes.
E
b
No requirements Operates less than 0.9 dB from theoretical performance limit
(<6.5 dB Eb/No for 1E-7 BER with Viterbi error correction only
Channel modulation BPSK or QPSK with ½ rate Viterbi error correction
Channel bit rates Selectable between 64 kbps and 2048 kbps. QPSK operation
from 512 to 2048 kbps
Channel bandwidth Selectable: -30 dB at 1.8 Rs or -30 dB at 1.4 Rs.
Power-up lock time Less than 90 seconds for carrier offsets +/- 200 kHz of
frequency setting
Data buffer 512k byte buffer for asynchronous output ports
Data output port Asynchronous: 1.2, 2.4, 4.8, 9.6, 19.2, 38.4, 57.6, 115.2
kbps RS-232 on DB-9 connector.
Time-division demultiplexer extracts control channel and one
to three data services from the nine services on the carrier.
Data services can be transparent asynchronous, statistically-
multiplexed asynchronous, or synchronous data.
NOTE: Baud rates 57600 and 115200 do not operate XON/XOFF or RR/RNR
methods of flow control.
