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 indicates in the event of any of
the following conditions:
• Absence of RF signals
• Absence of 9960 Hz modulation
• Absence of either 30 Hz modulations
• The RF level of a standard VOR deviation test signal is such
that the deflection of the deviation indicator is 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
0.5 to 2.7 seconds
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
