The Steerable TV interfaces with the:
- A.
  
  Servo control unit and video distribution unit (VDU)
- B.
  
  Symbol signal generator and radar scan converter
- C.
  
  VDU and symbol signal generator
Correct Answer
A. Servo control unit and video distribution unit (VDU)

Explanation
The Steerable TV interfaces with the Servo control unit and video distribution unit (VDU) because these components are responsible for controlling the movement and positioning of the TV, as well as distributing the video signals to the TV. The Servo control unit controls the motors and actuators that allow the TV to be steered in different directions, while the VDU receives the video signals and sends them to the TV for display. Therefore, the Steerable TV needs to interface with both the Servo control unit and VDU in order to function properly.

Rate this question:
12.

When an automatic light control (ALC) shutdown command in the steerable TV occurs,
- A.
  
  Video saturation disapperas and the system reverts to ALC FULL mode
- B.
  
  The system enters ALC FULL MODE
- C.
  
  The system reverts to STBY mode
Correct Answer
C. The system reverts to STBY mode

Explanation
When an automatic light control (ALC) shutdown command is initiated in the steerable TV, the system reverts to STBY mode. This means that the system goes into standby mode, indicating that it is no longer actively functioning or producing any output. The shutdown command causes the system to halt its operations and enter a dormant state until it receives further instructions or is manually restarted.

What is the primary source of IR?
- A.
  
  Sun
- B.
  
  Moon
- C.
  
  Earths Surface
Correct Answer
A. Sun

Explanation
The primary source of IR (infrared radiation) is the Sun. IR is a form of electromagnetic radiation that is emitted by objects due to their temperature. The Sun emits a significant amount of IR as it is a hot celestial body. This IR radiation is responsible for heating the Earth's surface and atmosphere. Other sources of IR include objects on Earth's surface, such as buildings and bodies of water, which absorb and re-emit the Sun's IR radiation. However, the Sun remains the primary source of IR due to its high temperature and continuous emission of this type of radiation.

Rate this question:

Light and IR cannot be
- A.
  
  Diluted
- B.
  
  Reflected
- C.
  
  Refracted
- D.
  
  Absorbed
Correct Answer
A. Diluted

Explanation
The statement "Light and IR cannot be diluted" means that light and infrared (IR) radiation cannot be mixed or diluted with any other substance or medium. This is because light and IR are forms of electromagnetic radiation that travel in waves and do not require a medium to propagate. They can travel through empty space or transparent materials without being affected or diluted.

Rate this question:
17.

The main difference between visible light and IR energy is
- A.
  
  The nature of the controlling medium
- B.
  
  The manner in which IR is processed
- C.
  
  That visible light can be refracted while IR cannot
Correct Answer
A. The nature of the controlling medium

Explanation
The correct answer is the nature of the controlling medium. This means that the main difference between visible light and IR energy lies in the characteristics of the medium through which they are controlled or propagated. The controlling medium for visible light is usually air or transparent materials, while for IR energy, it can be gases, liquids, or solids. This distinction in the nature of the controlling medium is what sets visible light and IR energy apart from each other.

Rate this question:
18.

Which is not a property of IR?
- A.
  
  Has frequency
- B.
  
  Has wavelength
- C.

Which piece of wire and cable test equipment uses the electromagnetic wave pulses to test cables?
- A.
  
  Time domain reflectometer
- B.
  
  Frequency counter
- C.
  
  Signal Generator
Correct Answer
A. Time domain reflectometer

Explanation
A time domain reflectometer (TDR) is a piece of wire and cable test equipment that uses electromagnetic wave pulses to test cables. It sends a pulse down the cable and measures the time it takes for the pulse to reflect back. By analyzing the reflected wave, the TDR can determine the length of the cable, locate any faults or disruptions in the cable, and measure the impedance or characteristic impedance of the cable. This makes it a valuable tool for troubleshooting and maintenance of cables in various industries such as telecommunications, networking, and electrical engineering.

Rate this question:
33.

Horizontal deflection on the cathode-ray tube on the time domain reflectometer equates to:
- A.
  
  Current
- B.
  
  Voltage
- C.
  
  Distance
Correct Answer
C. Distance

Explanation
In a time domain reflectometer (TDR), the horizontal deflection on the cathode-ray tube represents distance. This means that as the TDR sends a signal down a cable or transmission line, any impedance changes or faults in the line will cause reflections. These reflections are then displayed on the cathode-ray tube, with the horizontal deflection indicating the distance to the impedance change or fault. Therefore, the correct answer is distance.

To test the cable on the time domain reflect ometer use the standard:
- A.
  
  36 inch 50 ohm cable
- B.
  
  36 inch 25 ohm cable
- C.
  
  12 inch 50 ohm cable
Correct Answer
A. 36 inch 50 ohm cable

Explanation
The correct answer is 36 inch 50 ohm cable. This is because the time domain reflectometer (TDR) is used to measure the impedance and detect faults in a cable by sending a pulse down the cable and measuring the reflections. In order to accurately test the cable, it is important to use a cable with the same characteristics as the one being tested. Therefore, a 36 inch 50 ohm cable would be the appropriate standard to use for this purpose.

A time-domain reflectometer display that starts in the upper lect corner of the screen, drops down at mid-screen, and departs in the lower right indicates a(n)
- A.
  
  Short
- B.
  
  Open
- C.
  
  Frayed cable
Correct Answer
A. Short

Explanation
The given display pattern of the time-domain reflectometer indicates a short in the cable. When the display starts in the upper left corner and drops down at mid-screen, it suggests that the signal is reflecting back from a point close to the beginning of the cable. The departure in the lower right indicates that the reflection is occurring near the end of the cable. This pattern is consistent with a short circuit, where the signal is being reflected back due to a direct connection between the conductors.

If you press the TEST RPT Button on the transponder TS-3977 test set and aim the antenna at the ground the test code indication should be
- A.
  
  F
- B.
  
  O
- C.
  
  3
Correct Answer
B. O

Explanation
Pressing the TEST RPT Button on the transponder TS-3977 test set and aiming the antenna at the ground would result in the test code indication being "O".

You should remove the battery if the TS-3977 transponder test set is to be idle for more than:
- A.
  
  72 Hours
- B.
  
  48 Hours
- C.
  
  24 Hours
Correct Answer
C. 24 Hours

Explanation
The correct answer is 24 Hours. This is because leaving the battery in the TS-3977 transponder test set for more than 24 hours while it is idle can lead to battery drain and potential damage to the device. To prevent this, it is recommended to remove the battery if the test set is not being used for more than 24 hours.

THE TCAS test set does not test teh operation of the:
- A.
  
  Transponders
- B.
  
  Interrogators
- C.
  
  Mode S transponder
- D.
  
  Mode T transponder
Correct Answer
D. Mode T transponder

Explanation
The TCAS test set is used to test the operation of various components related to the Traffic Alert and Collision Avoidance System (TCAS). Transponders and interrogators are essential components of the TCAS system, as they facilitate the exchange of information between aircraft. The Mode S transponder is a specific type of transponder that allows for more advanced surveillance capabilities. However, the Mode T transponder is not a component of the TCAS system and therefore is not tested by the TCAS test set.

If you leave the batteries for the TCAS test set (T/S) on charge for an indefinate period of time, the batteries:
- A.
  
  Have no danger of overcharging
- B.
  
  Complete the charge cycle and the T/S shuts down
- C.
  
  Overcharge and must be replaced
Correct Answer
A. Have no danger of overcharging

Explanation
The correct answer is that the batteries have no danger of overcharging. This is because modern battery chargers are designed to prevent overcharging by automatically adjusting the charging current or voltage when the battery is fully charged. Therefore, leaving the batteries on charge for an indefinite period of time will not cause them to overcharge.
