How to Measure Current with an Oscilloscope Current Probe?
The main function of an oscilloscope probe is to bring the voltage signal being measured from the measurement point into the oscilloscope for measurement. Ideally, the oscilloscope probe should have no effect on the measured signal, but in reality, its long cable inevitably has stray inductance, capacitance, and resistance. Therefore, they will affect the oscilloscope’s … Read more
Understanding Oscilloscope Bandwidth
Recently, during interviews, I found that many hardware test engineers are completely unaware of the concept of oscilloscope bandwidth, and some with over three years of experience do not understand the concept of bandwidth. Some candidates can roughly state the conclusion: the recommended bandwidth for an oscilloscope should be 3-5 times the signal frequency. However, … Read more

Learning High-Speed Differential Probe Design for 20G Oscilloscope
Accurate measurement begins at the probe and probe end. Probes that match the oscilloscope and the device under test (DUT) can capture complete signals into the oscilloscope for maximum signal fidelity and measurement accuracy. To measure typical signals and voltage levels, passive probes can provide easy-to-use and various measurement capabilities at a reasonable price. However, … Read more
