It is a power supply where the user can vary the output voltage. YesTech variable DC power supply allows you to change the output voltage and current to the device under test.
An oscilloscope captures and displays signals in the time domain, while a spectrum analyzer captures and displays signals in the frequency domain. Sometimes, oscilloscopes have a built-in spectrum analyzer function to make it easy to analyze signals in both the time and frequency domains. ,
View Full VersionHow do I measure voltage? If you use a multimeter, anyone can measure it easily ■ Summary Since voltage is not visible to the naked eye, it is not possible to confirm "how much voltage is flowing through a circuit at a glance". However, the circuits of electronic devices have a set voltage for normal operation, and if the voltage is too high, it may lead to product malfunction or personal injury. In addition, ...
View Full VersionWhat does the frequency of electricity mean? Here are the basics of frequency, regionality, and measurement Since electricity and voltage are invisible things, many people will think they are elusive. But in fact, they are only invisible, and it is not difficult to understand them. Below, we will introduce the frequency basis of electricity and voltage in an easy-to-understand way, regional differences in frequency, and how...
View Full VersionAlternating current (AC) is a type of electric current whose polarity reverses periodically and whose amplitude varies continuously over time. AC power is often used in businesses and homes because it is cheaper and more efficient to generate and transmit than direct current (DC) power. During transmission, a transformer can reduce power loss by increasing or decreasing the voltage of the AC line. Alternating current (AC) is a form of household electricity -...
