701935 Signal Source

Improve switching-loss measurements by eliminating skew.

When using different types of probes, such as a voltage probe and a current probe, a small propagation delay difference exists between the probe pair. Small, but significant, this difference is caused by each probe’s unique internal circuitry and cable length.

This propagation delay difference is known as ‘skew’ and creates an error when calculating switching loss or measuring timing.

In the high speed switching of the switching power supply, the engineer is required to measure the timing of the control signal in nano seconds.

The 701935 Deskew Correction Signal Source accommodates nearly all types of clamp-on current probes for switched mode power supply (SMPS) testing.
