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 o/- 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.
