Figure 4.6-3, Squelch and AGC signals receiver unit
 RX_BUSY (REM, p.5)
Squelch output signal that is referenced to GND.
This signal can be used to detect that the receiver is busy on a connected transmitter unit, on
a remote control or an other unit that can use this signal.
The signal polarity can be configured.
 SQUELCH (AUX2, p.1 and p.2)
This signal indicates that the squelch is activated / closed.
The polarity can be configured. The output is a solid state relay, rated for maximum 100V /
100mA.
 AGC_HILO_P, AGC_HILO_N (AUX2, p.3 and p.6)
This signal indicates that a signal above approximately +40 dBuV is received.
This can be used to detect if the signal comes from a collocated transmitter operating on the
same frequency or a transmission from an aircraft.
 AGC VOLTAGE (AUX2, p.7)
This is an analogue output 0-5V. The output voltage is 0V for an input of xxx uV and increases
linearly with the input signal up to xxx uV where the voltage reach +5V.
