24
Q

What is a secure digital point-to-point legacy data link that operates in half-duplex?

25
What is a secure digital point-to-point data link that operates in full-duplex and uses serial transmissions?
Link 11b
26
What is a secure, frequency hoping (FH), line-of-sight (LOS) data link whose primary purpose is situational awareness and C2?
Link 16
27
What is the primary data link for USAF?
Link 16
28

Joint Tactical Information Distribution System (JTIDS) / Multi functional Information Distribution System (MIDS)
29
Why is Link 16 ill-suited for ground applications?
It's frequency band does not penetrate foliage or man-made structures and it does not bend around hills
30
A joint service secure, jam-resistant data link that is primarily used by ground forces for blue-force tracking (friendly troop position information) and digital data dissemination is called?
Enhanced Position Location Reporting System (EPLRS)
31
Situational Awareness Data Link (SADL) provides what four things?
Fighter-to-fighter, ground-to-air and air-to-ground communications in addition to air-to-ground combat identifications
32
What allows smooth and immediate transfer of electrical current between multiple sources and the load?
An Automatic Transfer Switch (ATS)
33
The transfer switch continues to ____________________, and when it is restored, switches the load ____________________ back to the utility power.
monitor utility power; from the generator
34
What does an uninterruptible power supply (UPS) system provide?
An alternate source of clean Alternating Current (AC) power in an emergency
35
The UPS system provides backup power to mask what type of outage?
Short-term outage
36
A reference point from which voltages are measured, a common return path or a direct physical connection to earth is?

Bonding
40
What are three methods of bonding?
Soldering, bolts/nuts/clamps and exothermic connection
41
What re five components of lightning protection?
Strike termination devices, bonding, cable conductors, grounding electrodes and surge protection devices

Shielding
43
What is the purpose of shieding?
To isolate electrical devices from their surroundings
44

Nuclear explosion
45
What are three measures to protect against the effects of an electromagnetic pulse?
Grounding, bonding and shielding
46
An electrostatic discharge (ESD) occurs when?
A positively or negatively charged material contacts a grounded object or and object of the opposite charge
47
What are two simple rules for substantially reducing the risk of electrostatic discharge (ESD) damage?
Handle all ESD sensitive items at an approved static controlled workstation Transport and store all ESD sensitive items (both reparable and serviceable) in static shielding (Faraday Cage) and non-charge generating packages or containers
