How does a vector network analyzer work?

February 14, 2025common problems 3670

A network analyzer consists of a signal source and a receiver. The receiver will detect changes in the output signal of the device (or network) and then compare it to the source signal fed into the device. To evaluate the effect of the device on current and voltage, the VNA measures the resulting amplitude and phase response. This results in transmission and reflection measurements, impedance, and s-parameters from which test engineers can characterize their device under test.

Why do you need to measure current? In this article, we will cover the reasons for measuring current, how to measure current and what to look for when measuring current. We cannot see the current that is flowing with our own eyes. Therefore, specialized measuring instruments are needed to measure current and other parameters. But why do we need to measure current? And how should we measure it? This article will detail the reasons for the need to measure current...

What is the difference between an oscilloscope and a spectrum analyzer/signal analyzer?
February 14, 2025 96
We usually use time as a frame of reference, focusing on when certain specific events will occur. This includes electrical events. Oscilloscopes allow you to view the instantaneous value of a particular electrical event (or the voltage value of some other event converted by an appropriate transducer) over time. In other words, we can use an oscilloscope to view the waveform of a signal in the time domain. Fourier theory...

What is a function/waveform generator?
February 14, 2025 403
A function generator is an electronic test device that generates a variety of standard waveforms for a device under test (DUT), such as sine, square, ramp, or sawtooth waveforms. In circuit design and circuit boards, testing often requires the use of controlled signals to simulate routine operations. Testing physical systems and sensors often requires stable and reliable signals that are as low as a few microvolts and may be as high as...

What is the purpose of an oscilloscope?
February 14, 2025 168
Test engineers and developers use oscilloscopes to display, visualize graphs, and analyze electrical signals during research and development, verification, quality assurance, and troubleshooting or debugging of electronic systems, boards, and integrated circuits. Oscilloscopes play a key role in a variety of applications and technologies across all industries, including high-speed digital electronics, optical communications, RF, power electronics, automotive and aerospace...
