Power Adapter Manufacturers With Senior Power Engineers

oscilloscope in the end how to use, senior power engineers to teach you

For power adapter engineers, the role of the oscilloscope is irreplaceable, once the product has a problem you need to catch the waveform, catch the timing, test the exact value to help engineers analyze, deal with, everything look at the waveform to speak. This requires accurate and reliable test data accurate figures can help us, distorted waveforms and values can only mislead us. So how to use the oscilloscope?

Engaged in the power industry for many years, oscilloscopes are equivalent to the engineer's left and right hands, but often found that many small companies in order to save money by using low-end products with low bandwidth and low sampling rate. They believe that oscilloscopes are simple to operate and can capture the waveform on the line. Even before the use of oscilloscopes, do not do the test preparation. This will only lead to distortion of test results and unreliable data.

Oscilloscopes need to be self-calibrated before use and require probe compensation adjustments, which are performed so that the probe matches the input channel. When operating the instrument for the first time and when displaying data from multiple input channels at the same time, it may be necessary to calibrate the data both vertically and horizontally to synchronize the time base, amplitude, and position. For example, calibration is required when a significant temperature change (> 5°) occurs.

Many junior engineers, when using multiple probes to measure power supply, just turn on the power supply product "fried", or even damage to the oscilloscope, that is because of the oscilloscope's channel and ground connection method is not understood. Oscilloscope multiple probes in the oscilloscope is a common ground. So when measuring the primary and secondary sides of the power supply at the same time, if one probe is connected to the ground of the primary side, and the other probe is connected to the ground of the secondary side, the internal channels of the oscilloscope are connected together, which is equivalent to short-circuiting the power supply's primary and secondary sides together, however, there is a voltage difference between the primary and secondary sides of the ground, and then the short-circuited current is easy to burn the product and the probes, and may even damage the oscilloscope.

Do power supply engineers, especially beginners, must be down-to-earth to learn, to operate, do not understand to ask, only then can grow up quickly.
