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 when a LOC deviation test signal is
applied.
The VLOC Course Deviation Flag must be flagged:
a) When the level of a standard deviation test signal
produces 50% or less of standard deflection of the deviation
indicator.
b) In the absence of 150 Hz modulation.
c) In the absence of 90 Hz modulation.
d) In the absence of both 90 Hz and 150 Hz modulation.
e) In the absence of RF.
From –99 dBm and –13 dBm input of a Standard VOR
Audio Test Signal, audio output levels shall not vary more
than 3 dB.
6 dB BW is greater than 9 kHz.
69 dB BW is less than 36 kHz.
a) With a standard deflection 'FLY LEFT' condition (90 Hz
dominant), the output shall be +90 mV ± 9 mV.
b) With a standard deflection 'FLY RIGHT' condition (150 Hz
dominant), the output shall be -90 mV ± 9 mV.
Greater than 60 dB.
Typical 0 ± 3 mV (Max error 9.9 mV per RTCA DO-195).
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.
