5.1.1

STANDARD TEST SIGNAL DESCRIPTION

A. Standard VOR Test Signal
An RF carrier, amplitude modulated simultaneously (a) 30 + 1% by a 9960Hz
subcarrier, which is in turn, frequency modulated at a deviation ratio of 16 by
a 30Hz + 1% "reference phase signal" and (b) 30 + 1% by a 30Hz + 1% "vari-
able phase signal" which can be varied in phase with respect to the reference
phase signal.
B. Standard Audio Test Signal
An RF carrier amplitude modulated 30% at 1000Hz.
C. Standard Localizer Test Signal
An RF carrier modulated simultaneously with 90Hz + .3% and 150Hz + .3%
signals so that the sum of their separate modulation percentages equals 40 +
2%.
D. Standard Localizer Centering Signal
A standard localizer test signal in which the difference in depth of modulation
is less than .002 (.1dB).
E. Standard Localizer Deviation Signal
A standard localizer test signal in which the difference in depth of modulation
of the 90Hz and 150Hz signal is .093 + .002 (4 + .1dB).
F. Standard Glideslope Test Signal
A -56 dBm RF carrier amplitude modulated simultaneously with 90Hz and
150Hz of each level so that when each signal is applied independently, the
carrier is modulated 40 + 2%.
G. Standard Glideslope Centering Signal
A standard glideslope test signal in which the difference in depth of modula-
tion of the 90Hz and 150Hz signals is less than .002.
H. Standard Glideslope Deviation Signal
A standard glideslope test signal in which the difference in depth of modula-
tion of the 90Hz and 150Hz signals is 0.091 + .002 (2 + .1dB).
