All modern oscilloscopes are digital storage oscilloscopes (DSOs) that use digital signal processing to capture and display analog signals. If the oscilloscope has the ability to observe these signals simultaneously in the digital domain, it is a mixed-signal oscilloscope (MSO). If the oscilloscope has a built-in spectrum analyzer function, it is a mixed-domain oscilloscope (MDO), although this term is less common.
A DC power supply converts alternating current (AC) electricity to DC electricity either by a linear method or a switching method. Switching power supplies are more efficient, lighter in weight and smaller in form factor. Linear power supplies can achieve lower noise, but this is no longer an advantage with modern switching power supplies. ,

View Full VersionVector network analyzers (VNAs) are test instruments that measure electrical network parameters. They are essential for radio frequency (RF) and microwave component analysis of a wide variety of passive and active devices including filters, antennas and power amplifiers. Network analyzers are ideal for transmission, reflection and impedance measurements as well as s-parameter measurements during design and production. Network analyzers...
View Full VersionThe article will cover the basics of impedance and points of measurement. Impedance is the resistance of an AC circuit and is invisible. Therefore, it must be measured using a specialized measuring instrument such as an impedance tester. People who have never touched an impedance tester before may be more concerned about how to use it and what to look for when using it. Therefore, this article will present in an easy-to-understand way the...
