Revision T
At -103.5 dBm (S+N)/N shall not be less than 6 dB.
At –103.5 dBm deviation output shall not be less than 60%
of standard deflection (90 mV) when a VOR deviation test
signal is applied (10 degrees course difference).
The VLOC Course Deviation Flag must be flagged:
a) in the absence of an RF signal.
b) in the absence of the 9960 Hz modulation.
c) in the absence of either one of the two 30 Hz
modulations.
d) When the level of a standard VOR deviation test signal
produces less than a 50% of standard deflection.
From -99 dBm to -13 dBm input of a Standard VOR Audio
Test Signal, audio output levels shall not vary more than
3 dB.
Greater than 60 dB.
The bearing information as presented to the pilot shall not
have an error in excess of 2.7° as specified by
RTCA DO-196 and EuroCAE ED-22B.
A minimum 100 mW into a 500 Ω load.
Less than 6 dB of variation between 350 and 2500 Hz. In
voice mode, an ident tone of 1020 Hz shall be attenuated at
least 20 dB.
The distortion in the receiver audio output shall not exceed
10% at all levels up to 100 mW.
6 dB BW is greater than 16.5 kHz.
