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.
Network analyzers perform component characterization tests. A network analyzer provides a calibrated excitation signal to an RF network or device under test (DUT) and measures the vector response at frequency with phase and amplitude information. A VNA provides transmission (transmission coefficient, insertion loss, gain), reflection (reflection coefficient, VSWR, return loss), and impedance measurements, as well as s...
View Full VersionA signal that looks very complex in the time domain behaves quite differently in the frequency domain. Time domain measurements show an impure sine wave. Without frequency domain measurements, it is still impossible to know the source and frequency of the second harmonic. Spectral analysis can show the spectral components individually, thus revealing the source of the interference. The information provided in the time domain (e.g., the signal pulse on...
View Full VersionWant to know how to use the current probe? Please first understand the following basic usage of the current probe and precautions for use. Since electricity is invisible, it is not possible to immediately determine whether a malfunction has occurred. In some cases, current measurements are required on a daily basis to prevent malfunctions, as well as to identify the cause of malfunctions when they do occur. Digital multimeters, clamp meters, and current probes can be used...
View Full VersionWhat is voltage? An easy-to-understand explanation of the difference from current and knowledge of units of measurement ■ Outline When using electronic equipment, you need to have a clear grasp of current, resistance, and voltage. However, there are many people who only know these words and do not understand them in detail. Here, we will explain in layman's terms what the definition of voltage is, what the difference between current and potential is,...
