- The exam is a proctored, in-person performance assessment - not a multiple-choice knowledge test.
- You'll troubleshoot MOSFET, IGBT, and SCR switching circuits using a multimeter, function generator, and oscilloscope.
- Passing requires 70% on assessment circuit cards run through a Nida 130E or later trainer.
Overview: Why the 13 Domains Matter
Basic Electricity and Electronics - Analog (BEE-A) is organized around 13 published content areas that CertTEC, a division of SpaceTEC Partners, Inc., uses to define what a competent analog electronics technician should be able to do at a bench. Unlike certifications that test theory in isolation, BEE-A's domains map directly onto physical circuit cards you'll manipulate during the exam. Understanding what each domain actually demands - not just its title - is the difference between walking in prepared and guessing your way through signal tracing.
This guide breaks down all 13 domains, explains how CertTEC weights practical skill over rote memorization, and shows you where to spend your limited study hours. If you haven't yet reviewed the fundamentals, pair this with the BEE-A Study Guide 2026 for a first-attempt strategy, and check BEE-A Requirements 2026 to confirm you meet an eligibility route before you register.
How the Domains Are Tested
Every one of the 13 domains gets tested through the same delivery format: a proctored, in-person performance assessment run through SPI's online Examination Management System. This isn't a bank of theory questions on a screen. You'll work with two CertTEC assessment circuit cards per discipline, connected to a Nida 130E or later trainer, and you'll use a multimeter, a function generator, and an oscilloscope to trace signals, measure values, and isolate faults.
That format changes how you should study each domain. Memorizing a definition of "thyristor" won't help you if you can't identify an SCR misfiring on a live card under a scope. If you're still deciding how demanding this format really is compared to what you expected, read How Hard Is the BEE-A Exam? Complete Difficulty Guide 2026 before committing your prep hours.
Key Takeaway
Study each domain with your hands on equipment whenever possible. A multimeter, function generator, and oscilloscope aren't optional study aids for BEE-A - they're the actual test instruments.
Domains 1-5: Semiconductor Devices
The first five domains build the device-level foundation everything else in the exam relies on. If you can't reliably identify device behavior on these first, later domains involving amplifiers and oscillators will be much harder to troubleshoot.
Domain 1: Diodes
Candidates must understand forward and reverse bias behavior, rectification, and common failure modes you'd find while signal tracing a power supply.
- Identifying a shorted or open diode with a multimeter
- Recognizing rectified waveforms on an oscilloscope
Domain 2: Transistors
Covers bipolar junction transistor and field-effect transistor operation, biasing, and switching behavior across common configurations.
- Testing transistor junctions with a multimeter's diode function
- Interpreting gain and switching behavior relevant to later amplifier domains
Domain 3: Thyristors
Focuses on SCRs, triacs, and related devices used for controlled switching - a practical skill area CertTEC explicitly emphasizes for troubleshooting.
- Recognizing SCR triggering and latching behavior on a scope
- Diagnosing a thyristor-based switching circuit that fails to fire correctly
Domain 4: Integrated Circuits
Tests your ability to work with IC packages as functional blocks - recognizing pinouts, expected inputs/outputs, and common failure symptoms rather than internal semiconductor physics.
Domain 5: Optoelectronic Devices
Covers LEDs, photodiodes, and optocouplers - devices that bridge electrical and optical signals in analog circuits.
- Verifying LED forward voltage and current limiting
- Testing optocoupler isolation behavior with a function generator input
Domains 6-8: Power, Measurement, and Math
These three domains are where CertTEC's practical focus becomes most obvious. The certifying body specifically highlights power-supply signal tracing and analog measurements as core exam skills, so these domains deserve dedicated bench time, not just flashcards.
Domain 6: Power Supplies
You'll trace signals through rectification, filtering, and regulation stages to locate a fault on a live circuit card - one of the most heavily practiced skills in the entire exam.
- Tracing AC input through rectifier, filter capacitor, and regulator stages
- Locating a stage where the expected waveform disappears or distorts
Domain 7: Test Equipment and Measurements
Tests your fluency with the actual instruments used throughout the exam: multimeter, function generator, and oscilloscope.
- Setting oscilloscope triggering and vertical/horizontal scaling correctly
- Choosing the right multimeter function and range for a given measurement
Domain 8: Mathematics and Formulas
Covers the calculations that underpin every other domain - Ohm's Law, reactance, gain in decibels, and frequency-related formulas you'll need to interpret waveforms correctly.
Domains 9-13: Signal and Circuit Design
The final five domains build on the device and measurement foundation to test how well you understand signal behavior across complete circuit stages.
Domain 9: Amplifiers
Covers gain, bandwidth, and configuration recognition across common amplifier stages you'd encounter on an analog circuit card.
Domain 10: Operational Amplifiers
Tests op-amp configurations - inverting, non-inverting, and feedback behavior - along with recognizing expected output waveforms for a given input.
Domain 11: Oscillators
Covers circuits that generate periodic waveforms without an external signal input, and how to verify frequency and amplitude with a scope.
Domain 12: Filters
Tests recognition of low-pass, high-pass, and other filter responses, including how a filter stage shapes a signal passed through it.
Domain 13: Wave-shaping Circuits
Covers clipping, clamping, and related circuits that intentionally alter waveform shape - a natural companion topic to the diode and filter domains earlier in the list.
Which Domains Deserve the Most Bench Time
Not every domain requires equal prep time. Based on CertTEC's stated practical focus areas and the equipment list required for the exam, three clusters stand out for extra attention.
| Domain Cluster | Why It Gets Priority | Key Tool |
|---|---|---|
| Power Supplies (Domain 6) | Explicitly named as a core practical focus area | Oscilloscope, multimeter |
| Thyristors (Domain 3) | SCR switching-circuit troubleshooting is a stated exam emphasis | Function generator, oscilloscope |
| Test Equipment and Measurements (Domain 7) | Every other domain depends on correct instrument use | Multimeter, function generator, oscilloscope |

A Domain-Based Prep Timeline
Rather than a generic weekly template, sequence your prep to follow the natural dependency chain between domains: device fundamentals first, then measurement fluency, then circuit-level troubleshooting.
Device Foundations
- Diodes, Transistors, Thyristors - bench-test each device type with a multimeter
- Review Mathematics and Formulas alongside device behavior, not in isolation
Instrumentation and Power
- Drill oscilloscope and function generator setup until it's automatic
- Practice full signal tracing through a power-supply stage from AC input to regulated DC output
Signal Circuits
- Amplifiers, Operational Amplifiers, Oscillators - identify expected waveforms for each
- Filters and Wave-shaping Circuits - practice recognizing shaped output on a scope
Integration and Review
- Run full mock troubleshooting sessions across Integrated Circuits and Optoelectronic Devices
- Time yourself on complete circuit-card fault isolation, not just individual measurements

Frequently Asked Questions
BEE-A covers 13 content areas: Diodes, Transistors, Thyristors, Integrated Circuits, Optoelectronic Devices, Power Supplies, Test Equipment and Measurements, Mathematics and Formulas, Amplifiers, Operational Amplifiers, Oscillators, Filters, and Wave-shaping Circuits.
No. BEE-A is a proctored, in-person performance assessment delivered through SPI's online Examination Management System, using assessment circuit cards, a Nida 130E or later trainer, and standard test instruments.
CertTEC doesn't publish numeric domain weights, but its stated practical focus areas - power-supply signal tracing, analog measurements, and MOSFET, IGBT, and SCR switching-circuit troubleshooting - point directly to Domains 6, 7, and 3 as high-priority study areas.
A passing score is 70%. For a full explanation of how that score applies to the performance assessment format, see BEE-A Passing Score 2026.
Not necessarily. Since device fundamentals like Diodes and Transistors underpin later domains such as Amplifiers and Oscillators, sequencing your study from device-level to circuit-level topics is more efficient than treating all 13 domains as isolated units.
