Testing and test equipment

- information about all aspects electronics testing, test methods, and test equipment.

Electronics test and test equipment are essential elements of electronics and radio. Electronic equipment can develop failures, or it may not work properly when it is built. In order to discover whether a circuit is working, and then where the problem is located, it is necessary to use various forms of test equipment.

The items of test equipment that are commonly found are multimeters, analogue and digital (DMM - digital multimeter), oscilloscopes, and under some circumstances more specialised test equipment including spectrum analyzers may be used.

Using a oscilloscopes
While multimeters are able to perform many tests, oscilloscopes are able to provide a unique insight into the working of an electronics circuit, because an oscilloscope is able to show the waveforms as well as being able to measure them.
