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.
The multimeter forms one of the most widely used items of test equipment. Learn about this aspect of electronics online though our test equipment tutorials.
Test systems and environments
Apart from the test equipment itself, testing often utilises one of a number of systems or environments to enable control, organisation.
