Tabulated Data - Continued
Table 1-1.
Characteristics
Specifications
50 ohms
Receiver Delay Gate (4)
Differential Voltage Logic (Note).
Logic 1 indicates valid signal data.
Receiver Set Fault Status
Power supply and temperature status signals
IF Signal Inputs
4 Wideband IF (WBIF) and 4 Narrowband IF
(NBIF) signals from the Receiver Set.
NBIF Signal Outputs (8)
-ldBm
with signal input level -32dBm.
Level
50 ohms
Carrier Presence Detector
(CPD) Status Output (4)
Detector Sensitivity
High Range
Adjust to ensure a sensitivity capable of
responding to NBIF input signals of 3 to
9 dB above average noise level.
Low Range
Adjust to ensure a sensitivity capable of
responding to NBIF input signals of 6 to
13 dB above average noise level.
Response time
Signal-to-noise ratio of 7 dB maximum
and a bandwidth of 25 kHz as follows:
a. Response time 2 milliseconds max.
-4
b. False alarm rate less than 4 X 10 .
c. Probability of detection 92% min.
Input Signal Level
-32 dBm
(O dBm REF) at a center fre-
quency of 24 MHz with receiver set for
automatic gain control (AGC).
Noise only input noise level -42 dBm
dBm.
VSWR
2.1 Max
Input impedance
50 ohms.
Integrator Done Signal (4)
Differential Voltage Logic (Note).
Logic "O" indicates the CPD has completed a
2 millisecond integration and that the CPD
status signal is valid.
