At -103.5 dBm (S+N)/N is not less than 6 dB.
-103.5 dBm or less for 60% of standard deflection.
The VOR Course Deviation Flag must be flagged when:
RF signals are absent.
9960 Hz modulation is absent.
either one of the two 30 Hz modulations are absent.
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 level does not vary more than 3 dB.
Greater than 60 dB.
The bearing information as presented to the pilot does 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 load.
Less than 6 dB of variation between 350 and 2500 Hz. In voice
mode, an IDENT tone of 1020 Hz Ident Tone is attenuated at least
20 dB down.
The distortion in the receiver audio output does not exceed 10% at
all levels up to 100 mW.
6 dB BW is greater than 16.5 kHz. 69 dB BW is less than 36 kHz.
At -103.5 dBm (S+N)/N is not less than 6 dB.
At -103.5 dBm, deviation output is not to be less than 60% of
standard deflection when a LOC deviation test signal is applied.
The VOR/LOC Course Deviation Flag is flagged when:
RF signals are absent.
9960 Hz modulation is absent.
one of the two 30 Hz modulations is absent.
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 level does not vary more than 3 dB.
6 dB BW is greater than 9 kHz
69 dB BW is less than 36 kHz
With a standard deflection 'FLY LEFT' condition (90 Hz dominant),
the output is +90 mV ± 9 mV.
With a standard deflection 'FLY RIGHT' condition (150 Hz
dominant), the output is -90 mV ± 9 mV.
Greater than 60 dB.
The bearing information as presented to the pilot does 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 load.
Less than 6 dB of variation between 350 and 2500 Hz. In voice
mode, an IDENT tone of 1020 Hz Ident Tone is attenuated at least
20 dB down.
The distortion in the receiver audio output does not exceed 10% at
all levels up to 100 mW.
