There are several ways to test a DC power supply, and here we present only 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 pens. If it is on, the multimeter will beep. This test is designed to determine if the power supply is energizing and if there are any breaks in the wiring.
Voltage Test: You can use the DC voltage mode of your multimeter to accomplish this test. Touch the positive and negative terminals of the power supply with the multimeter pens. The multimeter should display the voltage output from the power supply. Compare this voltage to the rated voltage of the power supply to make sure it is in the correct range.
Load Test: You can connect a load (such as a light bulb or motor) to the power supply and measure the voltage and current with a multimeter. The voltage should be stable and within the expected range; the current should be within the rated current of the power supply.
Ripple Test: You can measure the AC component of the power supply output voltage. Connect an oscilloscope to the output terminals of the power supply and measure the voltage ripple. The ripple voltage should be as low as possible and within acceptable limits.
Always test the power supply with care as specified in the operation manual and safety guidelines. If you are unfamiliar with electronic testing, it is best to consult a professional or use pre-constructed test equipment.
Network analyzers are key instruments used to measure the performance of RF and microwave devices, and their types can be categorized according to different criteria as follows: The selection of network analyzers needs to be based on the measurement needs (e.g., frequency range, accuracy, portability) and application scenarios (R&D...
View Full VersionNetwork 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 VersionDigital multimeters are used, and this article will detail their advantages and disadvantages. ■ SUMMARY Electronic devices are powered by electricity. However, because electricity is invisible, it is necessary to use measuring instruments such as digital multimeters to check their safety and quality and to find out why malfunctions occur. Digital multimeters have so many buttons and ports that many people find them difficult to manipulate at first...
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 -...
