Is it possible to generate DC power using an AC power supply?
524Can. Many AC power sources can produce DC directly, or by superimposing a DC bias on the AC waveform. ,

How to use the impedance tester
488In 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". ...

What is a current probe?
528Many 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...

How does a vector network analyzer work?
417A 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, which can be used by the test engineer to...
