Traditional analog-to high-power switching power supply, power and size of different types. They have to face the complex, dynamic work environment. Equipment and load demand may be changed in an instant. Even the "daily" switching power supply, but also to withstand far more than the average level of the peak moment. Design power systems or use to power engineers need to know in a static condition, as well as the power under the worst conditions of work.
     In the past, to describe the behavior characteristics of the power means to the use of digital multimeter measuring the static current and voltage, and calculator or PC hard calculation. Today, the majority will turn Oscilloscope engineers as part of their platform of choice for power measurement. Modern oscilloscopes can be equipped with integrated power measurement and analysis software, simplifies setup, and make more dynamic surveying easily. Users can customize the key parameters, automatic calculation, and in seconds see the results, not just raw data.
