RECORDING OF SIMULATOR-ERROR-CURVE
4.7.1
Error Curve of TX1
a) Switch on TX1.
C
Switch TX1 On
b) Note down 'T1 Azimuth Alignment' value.

Important for h)
c) Shift 'T1 Azimuth Alignment' for a 'M1 Azimuth' reading of 000.0°
A/EC

---,-°
NOTE:
Range of value: 0...359.9
d) Record in test sheet (Fig. 4-6) reading of 'M1 Azimuth' (e.g. 0.0°)
as 1st value.
e) Set phase reference for the 30 Hz FM signal to antenna 3 and re-

cord reading of 'M1 Azimuth' as 2nd value in test sheet.
Normal Operation
Antenna-3
f)
By incrementing twice select next but one antenna as 30 Hz phase
reference and record azimuth readings of 'M1 Azimuth'. Continue
this way until all 25 measurement values have been recorded. The
measured values have to increment in steps of 14.4°. Record the
differences from these nominal values in the error column.
A typical error spread is <
±
0.4°.
g) Set phase reference for the 30 Hz FM signal to antenna1.

Error Curve of TX2
Perform an error curve measurement for TX2 in the same way as for
TX1 (4.7.1).
