How to measure power factor quantitatively with oscilloscope in AC/DC switching power supply?
In fact, using Tektronix oscilloscope to measure power factor is to measure the phase difference between voltage and current, namely cos_. At the same time, Tektronix TDS5000 power debugging system also automatically measures the relevant parameters of PFC (such as THD, True Power, Apparent Power, Power Factor, etc.).
How to use oscilloscope to debug video parameters (including video output level, horizontal definition, brightness amplitude-frequency response, chroma amplitude-frequency response, brightness signal-to-noise ratio, chroma signal-to-noise ratio, brightness non-linear distortion, etc.)?
Tektronix TDS3000B Series Oscilloscopes plus TDS3VID or TDS3SDI and TDS5000 Series Oscilloscopes provide powerful video measurement functions, including analog HDTV functions and built-in vector oscilloscope capabilities, to help you analyze various video parameters.
Why is the waveform ringing of a 30MHz clock debugged with a Teck oscilloscope much larger than that of Angelen (the probe of the oscilloscope is 250MHz)?
When measuring state transition, only the oscilloscope's automatic trigger mode is needed, and the voltage and current waveforms are set as ideal display mode. If TDS5000 is used, the resolution knob can also be adjusted to adjust the sampling rate to the appropriate gear (generally about 10 times the signal frequency). Then the measured data are calculated automatically by using PWR2 software. For MOSFET, we choose Vds and Ids as the measured signal IGBT and Vce and Ice as the measured signal. When debugging switching power supply with digital oscilloscope, can we set the limit parameter value (such as debugging time, sampling number per time) beforehand, and how to debug switching power supply state conversion with Tektronix oscilloscope? Connection mode (for example), key setting of oscilloscope, necessary precautions.
