A broadcast engineer discovers corrosion on a coaxial transmission line connector after a severe storm. Which risk does this PRIMARILY introduce?
Answer: Increased impedance mismatch and signal loss
Connector corrosion increases contact resistance and creates impedance discontinuities, leading to signal loss and elevated VSWR.
What is the purpose of an automatic exciter changeover system in a broadcast transmitter plant?
Answer: To automatically replace a failed exciter with a standby unit
Automatic exciter changeover detects exciter failure and switches to a standby unit without operator intervention, minimizing on-air downtime.
Which environmental risk poses the greatest long-term threat to electronics stored in an uncontrolled broadcast equipment room?
Answer: High humidity and temperature cycling
High humidity accelerates corrosion on PCB traces and connectors, while temperature cycling causes thermal stress cracking of solder joints and component failures.
During a risk assessment, a broadcast facility rates a hazard as 'low probability but catastrophic impact.' How should this risk be treated?
Answer: Implement robust mitigation or transfer the risk via insurance
Catastrophic-impact risks must be mitigated or transferred regardless of probability because the consequence of occurrence is unacceptable.
A TV station's master control switcher fails live on-air. Which pre-planned mitigation allows fastest recovery?
Answer: Switching to a redundant backup switcher already in the signal path
A pre-configured backup switcher already in the signal chain allows immediate manual or automatic switchover without rerouting cables or waiting for equipment delivery.
What does 'risk transfer' mean in the context of broadcast facility management?
Answer: Shifting financial responsibility for a risk to a third party such as an insurer
Risk transfer shifts the financial burden of a risk event to another party, most commonly through insurance policies or contractual agreements.
A broadcast facility's fuel contract ensures the diesel generator tank is refilled within 4 hours of a low-level alert. Which risk management principle does this represent?
Answer: Risk mitigation through supply chain preparedness
Pre-arranged fuel delivery contracts are a supply chain mitigation that ensures generator fuel availability before it runs out during a prolonged outage.
