What are DC power supplies used for?
927A DC power supply provides a constant bias voltage or current to an electrical device, component, or circuit to ensure that the device under test operates as intended. ,
View Full VersionWhat is an AC power supply?
An AC power supply is responsible for providing AC power to the load. The power input can be either AC or DC. You need an AC power supply because the power from the wall outlet does not meet the specifications of the load. In order for the load to operate properly, you need to transform the AC power supply to tune the AC power from the supply to the voltage, current, and frequency required by the device. This can be accomplished by raising or lowering the voltage and then filtering the signal.
You can use an AC power supply for testing. The AC power supply can emulate grid outages, harmonics, surges, or other events that may cause the device under test (DUT) to fail.

How does a DC power supply work?
831A DC power supply converts alternating current (AC) electricity to DC electricity either by a linear method or a switching method. Switching power supplies are more efficient, lighter in weight and smaller in form factor. Linear power supplies can achieve lower noise, but this is no longer an advantage with modern switching power supplies. ,

What are the different types of oscilloscopes?
1106All 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. ,,...

What is a current probe?
1026Many people use digital multimeters to easily measure current, voltage, resistance, etc. However, there is a drawback to using a digital multimeter to measure current, namely: the circuit must be disconnected and the digital multimeter must be connected in series with the circuit under test in order to make the measurement. In this case, a current probe can be used instead of a digital multimeter to make measurements. Since the electrical connection of the circuit is no longer required, the current probe is more time-consuming...
