The correct probe supports accurate measurements. Our large oscilloscope probe selection includes industrial, active, passive and specialized probes that accommodate your unique requirements. Remember that probes can be designed as manufacturer/model-dependent. We can help you order an instrument that is compatible with your scope and application. Active probes require external power, while passive do not. The high-performance, active products contain components, such as transistors, and deliver accuracy in higher frequency measurements. We also provide insulated probes for safely capturing high-frequency measurements with portable oscilloscopes. You’ll find products from Fluke, Sigilent, Keysight Technologies and Ponoma to work seamlessly with your scope.
