Accurate high-frequency power measurements using a de-skew correction signal source

DE-SKEW CORRECTION ENHANCES ACCURACY OF OSCILLOSCOPE-BASED POWER MEASUREMENTS

High-frequency power measurements can now be carried out with greatly enhanced accuracy using a de-skew correction signal source, along with voltage and current probes, in conjunction with the /G4 power measurement option on the Yokogawa ranges of digital and mixed-signal oscilloscopes.

Even though power measurement using an oscilloscope is fundamentally less accurate than using a digital power meter, it offers much higher bandwidth.
It is particularly suitable for measuring high-frequency switching losses in switched-mode power supplies. It also provides a power measurement capability using a general-purpose product which has other uses, an option that may be more acceptable to users who are not ready to invest in a true power meter or have limited budgets for test equipment.

The de-skew correction signal source is an accessory which is specifically designed to maximise the measurement accuracy of oscilloscopes when they are used for power measurements involving fast switching devices and high-frequency waveforms.

The de-skew correction signal source supports through-type current transformers and a variety of clamp-on current probes.
