Works with the software in the Siglent SDS2000 Series oscilloscopes to provide test signals for the voltage and current probes so that the user can remove any timing errors caused by different delay times through the different probes.

(This option is only available on 4 channel units of SDS2000 and SDS2000X Series)

To make accurate power loss measurements, you must perform current and voltage channel deskew using the DF2001A deskew fixture. The channel deskew procedure calibrates the time delay between current and voltage probes. This step is certainly important since a small delay in the timing of the voltage and current traces can cause a large error in the instantaneous power reading.

The deskew accuracy is a function of the electrical characteristics of the voltage and current probes as well as the rise time of the signal under test. In general, higher bandwidth probes will allow better rise time fidelity and better deskew resolution.

You need to perform the deskew procedure once initially, and you should re-run the procedure when any part of the hardware setup changes (for example, a different probe, different oscilloscope channel, etc.) or when the ambient temperature changes.
