View Full VersionAn oscilloscope is a test instrument used to capture and display a graph of the waveform of an electrical signal over time. For example, it can graph voltage (y-axis) versus time (x-axis) on its display. Oscilloscopes are powerful tools for designing and testing electronic equipment. They play a very important role in determining whether system equipment components are working properly and which components are malfunctioning. They...
View Full VersionThere are several ways to test a DC power supply, here we only introduce a few common methods. Conductivity test: You can use the multimeter's conductivity mode to accomplish this test. Touch the positive and negative terminals of the power supply with the multimeter pen. If it is on, the multimeter will beep. This test is designed to determine if the power supply is delivering power and if there are any breaks in the wiring. Voltage...
View Full VersionAll modern oscilloscopes are digital storage oscilloscopes (DSOs) that use digital signal processing to capture and display analog signals. If the oscilloscope has the ability to observe these signals simultaneously in the digital domain, it is a mixed-signal oscilloscope (MSO). If the oscilloscope has a built-in spectrum analyzer function, it is a mixed-domain oscilloscope (MDO), although this term is less common. ,,...
