View Full VersionMany people use digital multimeters to easily measure current, voltage, resistance, etc. However, there is a drawback to using a digital multimeter to measure current, namely: the circuit must be disconnected and the digital multimeter must be connected in series with the circuit under test in order to make the measurement. In this case, a current probe can be used instead of a digital multimeter to make measurements. Since the electrical connection of the circuit is no longer required, the current probe is more time-consuming...
View Full VersionIn this article, we will describe the basic measurements of an impedance analyzer. Overview An impedance tester is an instrument used to measure AC resistance or impedance. This article will introduce the basic knowledge about impedance, the measurement method of impedance, and how to use the impedance tester. What is impedance? What is impedance? In short, it is "a quantity that indicates the difficulty of the flow of alternating current". ...
View Full VersionThe selection criteria for a VNA depends heavily on the application or usage scenario. Typically, selection criteria include frequency range, number of ports required (from 2 to 24 (multiport) and even 48 (with switching matrix)), output power, and instrument class from economy to handheld to high-end. Vector network analyzers are both signal generators and receivers...
