Guard Receiver ET4400G
Guard (distress) frequencies 121.5 MHz and 243 MHz in parallel at
the same time
Input signal protection ≤+21 dBm
Sensitivity (with AM (m = 0.3),
121.5/243 MHz)
ITU-T S+N/N = 10 dB
≤–101 dBm
Image and spurious rejection 80 dB
Selectivity (IF bandwidth) ≥30 kHz/6 dB, ≤75 kHz/60 dB
AM internal noise level
(with input signal –47 dBm,
f
m
= 1 kHz, m = 0.8) (S+N)/N = 40 dB (modulated-to-
unmodulated), weighted to ITU-T
Note: If a guard receiver with common main receiver antenna is installed in an
M3SR, the sensitivity of the main receiver is reduced by 4 dB.
