A digital multimeter, or DMM, is a test instrument used to measure electrical values including voltage, current, and resistance—though modern DMMs perform many more types of measurements.
Spectrum analyzers are expensive test instruments, so it's essential to choose the best one for each application. Understanding the basic specifications—as well as the differences between analog/superheterodyne spectrum analyzers, FFT spectrum analyzers, and even real-time spectrum analyzers—can be crucial.
A signal generator is an electronic device that produces repeating or non-repeating electronic signals in either the analog or digital domain. The generated signals are used as stimuli for electronic measurements, typically in the design, testing, troubleshooting, and repair of electronic or electroacoustic devices—though they often have artistic applications as well.
Power meter for measuring and analysing power … capable of measuring all AC and DC parameters, including power, current, voltage, power factor, frequency, and phase.
A function generator is typically an electronic test device or software used to generate various types of electrical waveforms over a wide range of frequencies. Some of the most common waveforms produced by a function generator include sine waves, square waves, triangle waves, and sawtooth waveforms.
The first stage: a spectrum analyzer is designed to analyse the nature of signals fed into it. A network analyzer, on the other hand, generates a signal and uses it to analyse a network or device. RF network analyzers are used to measure components, devices, circuits, and subassemblies.
An LCR meter is a type of electronic test equipment used to measure the inductance (L), capacitance (C), and resistance (R) of an electronic component. In simpler versions of this device, the impedance is measured internally and converted to a displayed value of the corresponding capacitance or inductance.
There are three main types of power supplies: unregulated (also known as brute-force or raw power supplies), linear regulated, and switching power supplies.
An electronic load is a type of device that applies voltage and draws current. Also known as a programmable load, AC or DC electronic loads can be used by power supply manufacturers, battery developers, solar or wind energy producers, and others who want to thoroughly test their power sources.
An oscilloscope, formerly known as an oscillograph and informally referred to as a scope or o-scope, CRO (for cathode-ray oscilloscope), or DSO (for the more modern digital storage oscilloscope), is a type of electronic test instrument that graphically displays varying signal voltages, usually as a two-dimensional plot of one or more signals as a function of time. Other types of signals (such as sound or vibration) can be converted into voltages and displayed as well. Oscilloscopes show how an electrical signal changes over time.
