Eliminate the time deviation between voltage probe and current probe
To use digital oscilloscope for power supply measurement, it is necessary to measure the voltage and current between the drain electrode and the source electrode of MOSFET switching device, or the voltage between the IGBT collector and the emitter electrode. This task requires two different probes: a high voltage differential probe and a current probe.The latter are usually non-insertion hall effect probes.Each of these probes has its own unique transmission delay. The difference between these two delays, known as time deviations, can cause inaccuracies in amplitude measurements and time-related measurements.It is important to understand the effect of probe transmission delay on maximum peak power and area measurements.After all, power is the product of voltage and current. If two variables are not properly corrected, the result will be wrong.The accuracy of measurements such as switching losses can be affected when the probe is not "time offset corrected" correctly.
