What is a digital multimeter?

common problems 4890

A multimeter is an instrument that can measure a wide range of parameters, such as alternating (AC) or direct current (DC) voltage, AC or DC current, resistance, temperature, capacitance, and so on. Modern digital multimeters use digital and logic technology to become smaller and smaller with more and more built-in functions. By introducing digital technology, thedigital multimeterThe meter can provide graphical display, data logging and signal digitization, and programming functions, as well as communication with external devices.

  • How does a spectrum analyzer work?

    575

    A signal that looks very complex in the time domain behaves quite differently in the frequency domain. Time domain measurements show an impure sine wave. Without frequency domain measurements, it is still impossible to know the source and frequency of the second harmonic. Spectral analysis can show the spectral components individually, thus revealing the source of the interference. The information provided in the time domain (e.g., the signal pulse on...

  • What are network analyzers used for?

    417

    Network analyzers perform component characterization tests. A network analyzer provides a calibrated excitation signal to an RF network or device under test (DUT) and measures the vector response at frequency with phase and amplitude information. A VNA provides transmission (transmission coefficient, insertion loss, gain), reflection (reflection coefficient, VSWR, return loss), and impedance measurements, as well as s...

    What is resistance in electricity? This article will cover the basics of resistance, how to calculate resistance, and resistors. Many people have heard the word "resistance" when they were students, but may still not understand it. However, because they don't understand it, they are hesitant to ask people about it now. Simply put, resistance is a force that flows in the opposite direction of the current. Resistance...

  • How to use VNA?

    428

    Vector network analyzers measure a wide variety of devices and networks and offer a wide range of measurements for a variety of usage scenarios, such as spectrum analysis, pulse measurements, power amplifier (PA) characterization, and active device testing. The following guide describes how to set up a network analyzer for measurements, calibrate the measurement system, and interpret the measurement results: The uses of VANs are so wide-ranging that each measurement...
