3.4.32 O u t p u t s :
3.4.32.1 Identify
Output - T h e audio identity tone output
shall be adjustable at the control unit to provide a maximum of
not less than 100 milliwatts of 1350 cps power into a 600 ohm
resistive load during identity tone operation in the REC and T/R
m o d e s . The audio power output shall not vary more than 3 db
over an RF input signal range of -90 dbm to zero dbm. A c c i -
dental shorting or opening of the output circuit external to the
equipment shall not cause damage to the equipment or render
other functions of the equipment inoperative.
3.4.32.1.2
Identitv Tone Impedance - The control cir-
cuit
shall provide for identity tone input and output nominal im-
pedance of 600 ohms.
3 . 4 . 3 2 . 2 Distance Outputs - The Range Mechanical
m o d u l e (Paragraph 3.5.1.4(5) shall provide the following dis-
tance outputs for a computer.
3 . 4 . 3 2 . 2 . 1 D i s t a n c e S y n c h r o T r a n s m i t t e r s - Three dis-
t a n c e synchro transmitters shall be provided, Each synchro shall
be positioned in such a manner as to provide distance data of a
n a t u r e regarding units, tens and hundreds, respectively. A syn -
t h e t i c hundreds synchro transmitter is permitted.
3 . 4 . 3 2 . 3 Bearing Outputs - The Bearing Mechanical
module of 3.5.1.4(9) shall provide the following bearing outputs
f o r a computer.
3.4.32.3.1
TACAN Bearing Output - The Bearing Mecha-
nical module shall provide a synchro output of constant phase
relationship to the TACAN bearing.
3 . 4 . 3 2 . 3 . 2 Bearing Differential Synchro Transmitter
Output - A relative bearing output shall be provided by a differen-
tial synchro transmitter whose inputs shall be the TACAN bearing
angle and the heading reference signal.
