A benchtop DC power supply is a power supply that is mounted to an engineer's workbench for use. It usually has a large, legible display and user interface to allow the engineer to easily achieve full control of the power supply from the front panel. Users can also control modern benchtop power supplies through software. In addition, engineers can easily access the output terminals from the front.
The Variable Benchtop Power Supply is a convenient tool for testing circuits because you can adjust the voltage at any time. If your project has specific voltage requirements or you haven't finished the power supply portion of the design, a bench power supply can help.
The 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...
View Full VersionA 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...
View Full VersionThere are many brands and types of oscilloscopes on the market and they may look different, but most have the same basic steps. Here is a step-by-step guide on how to use an oscilloscope: ,
