7-56. What is the primary differencebetween the azimuth and elevationdrive subsystems?1. Manual override is only usedfor azimuth2. A computer is not used forazimuth3. Tachometer feedback is not usedin elevation circuitry4. Gimbal drive circuitry isdifferent7-57. In the FWD mode of operation, thereceiver head is slewed to whatelevation position?1. 0°2. -2°3. -3°4. -4°7-58. What is the primary function of thecontrol servomechanism BITEsubsystem?1. To maintain constant servo syncpulses2. To automatically locateservo-system failures3. To isolate component failures4. To convert computer Inputs togimbal bits7-61. During BITE 1 test, the receiverhead is slewed to what position?1. 0° azimuth and 0° elevation2. 0° azimuth and 4° elevation3. 0° azimuth and -4° elevation4. 4° azimuth and -4° elevation7-62. During BITE 2 test, the receiverhead is slewed to what position?1. 60° azimuth and -130° elevation2. 60° azimuth and 130° elevation3. 130° azimuth and -60° elevation4. 130° azimuth and 60° elevation7-63. The TTSC is used in what mode ofoperation?1. Computer2. Azimuth3. Elevation4. Manual7-64. Adjusting the thumb control on theTTSC produces voltage outputs fromwhich of the following transducer?1.
