Probes
What is a Probe?
A probe is a device that takes and relays measurements.
Types of Probes
- Differential probes- active analog voltage probe types including switch probes, available for high-speed and high-voltage needs.
- Logic probes- monitor signals temperature probes, either isolated or non-isolated (compare to multimeter probes).
- Active probes- analog voltage probe types, including differential and single-ended.
- Passive probes- analog voltage probe types, available in general-purpose, high voltage, and low capacitance needs.

To best utilize SiC devices for improved energy efficiency in equipment, it is important to optimize the internal device peripheral circuits in the inverter according to the device characteristics.
In research published by Yale University's Journal of Industrial Ecology (now owned and managed by the International Society of Industrial Ecology), researchers from the University of Nottingham and Dartmouth University use a Yokogawa Test&Measurement CW240 Clamp-On Power Analyzer to measure the real power consumption of the investigated printing systems.
