TEST DATA SHEET
E. VOR Alarm signal (Internal Display)
Input a standard VOR signal into the unit, with the modulation modified as
follows:
1. In the VOR CDI mode (Ref fig. 3-4):
Ref. only applied _________ “Flag” Displayed
Var. only applied _________ “Flag” Displayed
2. In the VOR Bearing mode (Ref. fig. 3-6):
Ref only Applied _________ 3 dashes displayed
Var only Applied _________ 3 dashes displayed
VOR Alarm signal (External Indicator drive)
Input a standard VOR signal into the unit and measure the voltage across the
Flag outputs (with positive lead of voltmeter connected to +Flag), with the
modulation modified as follows:
Ref. only applied _________ NMT 125 mV
Var. only applied _________ NMT 125 mV
VOR TO/FROM Flag (External Indicator drive)
Set the PTS to the 0 degree heading. Signal Generator set to respective
FROM radial. Measure voltage across TO/FROM output. Positive lead of volt-
age connected to +TO output.
75 degree _________ NMT -270 mV & NLT -900 mV
285 degree _________ NMT -270 mV & NLT -900 mV
255 degree _________ NMT +270 mV & NLT 900 mV
105 degree _________ NMT +270 mV & NLT -900 mV
6. AGC
Vary the input from -99dBm to -27dBm with a standard audio test signal. Mon-
itor the receiver output.
112.5 MHz: Audio level variation _____________ dB (3dB Max)
Vary the input from -99dBm to -27dBm with a standard VOR test signal. Mon-
itor the CDI with the OBS set to 0.
Bearing Variation ____________ (0.67° max
1
at 0 “FROM” radial,
