How does an oscilloscope work?

February 14, 2025common problems 8340

An oscilloscope uses a probe to connect to a test point in a circuit and amplify or attenuate the voltage at that point. The subsequent signal path depends on the oscilloscope, but in general, analog circuits condition the signal and analog-to-digital converters digitize it for further evaluation, processing, and analysis.

How to use the current probe
February 14, 2025 1035
Want 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...

How do I connect two DC power supplies in series?
February 14, 2025 942
To connect two DC power supplies in series, connect the positive terminal of the first power supply to the negative terminal of the second power supply to form a "daisy-chain" connection, where the series voltage is the sum of the voltages of the two power supplies. To connect two DC power supplies in series, proceed as follows: Note that the voltage of the load should be equal to or higher than the sum of the voltages of the two power supplies to prevent damage to the load or power supply. In addition, the load's rated...

How do I test a DC power supply?
February 14, 2025 913
There 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...

How to build a DC power supply?
February 14, 2025 944
You can build a DC power supply by converting AC to DC using an AC-DC converter or rectifier, and then using a voltage regulator to maintain a stable output voltage. The basic steps for constructing a DC power supply are as follows: Please note that constructing a power supply requires familiarity with electronic and electrical safety. It is best to consult a professional or use a pre-built kit to avoid danger. ,
