Sensitivity
-87 dBm or less for 60% of standard deflection.
Centering Accuracy 0
r
.0091 ddm or 0
r
7.8 mV.
Selectivity
The course deviation shall be 0 ddm
r
.0091ddm when using
the Glideslope Centering Test Signal as the RF frequency is
varied
r
17 kHz from the assigned channel.
At frequencies displaced by
r
132 kHz or greater, the input
signal shall be at least 60 dB down.
Standard deflection a) With a standard deflection ‘FLY DOWN’ condition (90 Hz
dominant), the output shall be -78 mV ±7.8 mV.
b) With a standard deflection ‘FLY UP’ condition (150 Hz
dominant), the output shall be +78 mV ±7.8 mV.
Flag
The unit Flags:
a) When the level of a standard deviation test signal
produces 50% or less of standard deflection of the deviation
indicator.
b) In the absence of 150 Hz modulation.
c) In the absence of 90 Hz modulation.
d) In the absence of both 90 Hz and 150 Hz modulation.
e) In the absence of RF.
