CBT Certified Broadcast Technologist Exam Overview
The Society of Broadcast Engineers (SBE) Certified Broadcast Technologist (CBT) exam tests your knowledge across core broadcast engineering disciplines. The exam covers broadcast signal fundamentals, transmission systems, audio and video systems, FCC regulations, and safety procedures.
Broadcast Signal Fundamentals
You need a strong grasp of RF spectrum allocation, modulation types including AM, FM, and ATSC digital television, and how signal propagation behaves in real-world environments. Understanding path loss, multipath interference, and antenna patterns is essential for the exam.
Transmission Systems
Questions on transmitters cover both solid-state and tube-based designs, power output calculations, and efficiency ratings. Antenna theory — including gain, polarization, and radiation patterns — combines with feedline types (coaxial, waveguide, and hardline) and STL (studio-to-transmitter link) system design.
Audio and Video Systems
Broadcast facilities depend on signal routing, monitoring, and proper level alignment. The CBT exam tests analog and digital audio levels (dBu, dBFS), video signal timing, sync generators, and distribution amplifiers. Understanding SDI, HDMI, and IP-based video transport is increasingly important.
FCC Regulations and Licensing
SBE certification candidates must understand FCC Part 73 (broadcast stations), Part 74 (auxiliary broadcast services), and EAS requirements. Knowing license maintenance, public inspection file obligations, and main studio rules is tested directly.
RF Safety and Tower Safety
FCC RF exposure guidelines (OET Bulletin 65) define maximum permissible exposure limits for workers and the general public. Tower climbing safety, fall protection, RF burn awareness, and OSHA tower safety standards round out the safety section of the exam.
How to Study for the CBT Exam
Start with the SBE Study Guide for the Certified Broadcast Technologist exam, which maps directly to the exam content outline. Focus your early study sessions on RF fundamentals — many candidates underestimate how heavily the exam weights signal propagation and modulation theory.
Troubleshooting Methodology
The CBT exam includes scenario-based troubleshooting questions. Practice a systematic approach: verify the signal source, trace the signal path, isolate the fault to a single stage, and confirm the repair. Common fault scenarios include mismatched impedance, failed finals in transmitters, and audio level misalignment.
SBE Certification Process
To sit for the CBT exam, you register through the SBE website, pay the examination fee, and schedule your appointment at a Prometric center. After passing, you receive your certificate and SBE membership benefits. Maintaining certification requires earning SBE Technical Education (STE) points through training, teaching, or attending SBE events over a five-year cycle.

Using This CBT Practice Test PDF
Print this PDF and work through every question under timed conditions. The CBT exam rewards candidates who can recall facts quickly, so timed practice is more valuable than open-book review alone. After scoring your practice test, group your wrong answers by topic area and spend focused study time on each weak zone before attempting another full practice round.
Broadcast technology evolves quickly. Make sure your study materials reflect current ATSC 3.0 standards, IP audio routing, and updated FCC EAS rules, as older study guides may not cover these areas adequately. The SBE website publishes the current exam content outline — use it as your checklist to confirm you have covered every topic before your test date.

Sample Certified Broadcast Technologist Practice Questions
Try these questions from our free Certified Broadcast Technologist practice tests. The correct answer and an explanation follow each question.
A broadcast station receives a Required Weekly Test (RWT) of the Emergency Alert System (EAS). What is the station's primary obligation regarding this test?
- A. Re-transmit the test to the public immediately.
- B. Log the receipt of the test.
- C. Notify the State Emergency Communications Committee (SECC) of successful receipt.
- D. Originate a new RWT within the hour.
Answer: B. Log the receipt of the test.
FCC rules require that EAS participants log the receipt of Required Weekly Tests (RWTs). Unlike Required Monthly Tests (RMTs), stations are not required to re-transmit RWTs to the public. The purpose is to verify that the equipment can receive the alert.
When performing maintenance on a high-power FM transmitter, a technician needs to test the transmitter's output stage without broadcasting a signal over the air. Which piece of test equipment is essential for this procedure?
- A. A spectrum analyzer
- B. An oscilloscope
- C. An RF dummy load
- D. A field strength meter
Answer: C. An RF dummy load
An RF dummy load is a device that simulates an antenna, allowing a transmitter to be tested at full power without radiating signals. It absorbs the RF energy and converts it to heat. Testing a transmitter without a proper load (like an antenna or a dummy load) can cause the power to be reflected back into the transmitter, potentially causing severe damage. A spectrum analyzer, oscilloscope, or field strength meter are used for measuring signals, but not for safely absorbing the transmitter's full power output.
A transmitter's VSWR suddenly spikes to 3:1. What is the FIRST corrective action a broadcast technologist should take?
- A. Increase transmitter power output
- B. Inspect the transmission line and antenna for faults
- C. Replace the exciter module
- D. Adjust the audio processing chain
Answer: B. Inspect the transmission line and antenna for faults
A high VSWR indicates an impedance mismatch, most commonly caused by a transmission line or antenna fault that must be located and corrected.
A broadcast facility's UPS system shows an abnormally high battery discharge rate during a utility power outage. What should the technologist investigate first?
- A. Adjust the UPS output frequency
- B. Check for overloaded circuits or failed battery cells
- C. Recalibrate the bypass switch
- D. Replace the static transfer switch
Answer: B. Check for overloaded circuits or failed battery cells
Excessive discharge rate typically indicates either more load than rated capacity or degraded battery cells that cannot hold full charge.
