2. Use test leads or some other suitable means to short TP1004 to TP1002. When
properly shorted, the output signal will be a very stable reading on the frequency
counter.
3. Adjust potentiometer R1007 for an output frequency of 8930 Hz +/- 160 Hz.
4. Remove the short between TP1004 and TP1002. Short TP1004 to TP1003.
5. Adjust potentiometer R1008 for an output frequency of 11360 Hz +/- 250 Hz.
5.2.2.3.6 VOR converter
1. GO to VORC page and inject a standard VOR test signal with 0 degree “from” at
113.50MHz, -73 dBm.
2. Push the Nav Frequency Transfer button. The Unit display will flash as the calibra-
tion is performed automatically.
5.2.2.3.7 LOC converter
5.2.2.3.7.1 Centering offset correction.
1. Go to the VLCO page.
2. Monitor the voltage bLEFT and +RIGHT (P165A2-J and P165A2-5) with a
DVM set to show Volts to 4 decimal places.
3. Adjust VLCO using the NAV inc/dec knobs to achieve a reading of
0.0000 V ± 0.0002 V.
5.2.2.3.7.2 Course width correction.
1. Go to the VLCW page.
2. Adjust VLCW using the NAV inc/dec knobs to achieve a reading of
0.1500 V ± 0.0002 V.
5.2.2.3.7.3 Centering
1. Go to LOC C page and inject a standard LOC centering signal at 111.70 MHz,
-73dBm.
2. Push the Nav Frequency Transfer button. The Unit display will flash as the calibra-
tion is performed automatically.
5.2.2.3.8 VOR/LOC Composite Level
1. Apply a standard localizer centering signal with the 90 Hz component removed at
111.7MHz, -73dBm to the NAV antenna.
2. Monitor the composite level at P155A1pin H with an rms voltmeter.
3. Adjust COMP using the NAV inc/dec knobs so that the composite level is NLT 0.267
VRMS and NMT 0.277 VRMS.
