ET 289B - Electrical Troubleshooting

Credits: 1-4

Description
Maintenance and service of electronic equipment and troubleshooting techniques using electrical measuring and test devices. This course is designed for students who have completed electronics courses that cover DC-AC electronics, semiconductor devices, and digital electronics or have at least 2 years of experience in electronics.

Student Learning Outcomes

Troubleshoot and repair unregulated half-wave, full-wave, and bridge rectifier and power supply circuits. In addition, they will understand voltage double/tripler unregulated power supplies.
Understand testing and troubleshooting DC and AC bias points, frequency response, bode plots, gain vs. phase measurements, single and multistage amplifier circuits using bi-polar transistors.
Build complementary symmetry circuits, push-pull circuits and measure the crossover distortion.
Understand testing and troubleshooting transformer-coupled amplifier circuits, tuned circuits, Q vs. bandwidth, and frequency response of tuned circuits.
Test and troubleshoot various operational amplifier circuit configurations. Understand CMRR, input bias currents and offset voltage, slew rate limiting aspects of operational amplifiers.
Understand integrated circuit voltage regulator measurements, line and load regulation.
Troubleshoot digital circuits. Understand fan out, noise margin, open and short circuit characteristics of logic circuits, and other characteristics of logic circuits.
Understand the testing and measurement of optical and temperature sensors.

Prerequisite: None
May Be Repeated: For up to a total of 4 credits
