Electronic Testing Equipment, And Their Types

Electronic test equipment refers to equipment used for detecting faults in device operation. This equipment creates stimuli signals and records the responses of electronic devices. When faults are discovered, electronic testing equipment from Mektronics can trace them and fix them. Most often, all electronics and circuits have been tested to find faults or abnormal functioning.

Basic Electronic Testing Equipment

Test equipment is required to determine and analyze the circuit conditions. This equipment can be used for maintenance and checking of electronic test equipment. Many industries use different types and models of electronic test equipment, from the simple and inexpensive to the more sophisticated and complex.


There are two types, analog and digital, of voltmeters. An analog voltage meter moves a pointer on a scale in proportion to the voltage within an electrical circuit. The digital voltmeter measures unknown input voltage by converting it into a digital value through a converter. It then displays the voltage numerically.


An ohmmeter (an electrical instrument that measures electrical resistance) is a name for an instrument that measures this property. Micro-ohmmeters is instrument that measures small values of resistance. For large resistance measurements, the megohmmeters will be used. Resistance values are measured by ohms. Originally, an ohmmeter had a small battery to supply voltage to resist.


Ammeters measure electric current in amperes (A). Earlier ammeters used the earth’s magnetic field to operate. In the 19th century, better instruments were developed that could be placed in any location and allowed for precise measurements in electric power systems.

Power Supplies

A power supply can be described as an electronic instrument that supplies electricity to an electric load. A regulated power supply refers to a power source that supplies various output voltages to perform bench testing of electronic devices. This power supply can either have a preset voltage or a variation of the output voltages. Nearly every electronic circuit requires a DC power source for operation. A regulated power source is composed of various blocks, including an ordinary voltage regulating device and a power supply. The ordinary power supply generates its output and is fed to the voltage-regulating device, which produces the final output. A power supply has the primary function of converting one type of electric energy into another.


A signal generator is also known as a pitch generator, function generator, or frequency generator is an electronic device that produces electronic signals in digital and analog domains (repeating or not-repeating signals). Signal generators can also be used in the design, testing, and repair of electro-acoustic and electronic devices.

Signal Generator

The vast majority of electronic devices are not suitable for all applications. There are many kinds of signal generators, each with its purpose and application. The market has seen the introduction of flexible, programmable software tone generators that are embedded with hardware units.

Digital Pattern Generator

A digital generator refers to an electronic testing apparatus or software used in the generation of digital electronics stimuli. These are specific types of electronic waveforms. They can vary between two common voltages, which correspond with two logic gates (either 0, low or high), and they can also be varying in frequency. The function of a digital pattern generator is the stimulation of an electronic device’s inputs.
