Product Specifications

Technical details and manufacturing context for Probes

Definition
Probes are essential accessories for oscilloscopes that physically and electrically connect the measurement instrument to the circuit or device being analyzed. They serve as the critical interface that transfers the electrical signal from the test point to the oscilloscope's input channel while minimizing signal distortion and loading effects.
Working Principle
Probes work by establishing a physical connection to the test point, then conditioning and transmitting the electrical signal through a cable to the oscilloscope. They typically incorporate impedance matching networks, attenuation circuits, and shielding to preserve signal integrity. Active probes may include amplifiers to boost weak signals, while passive probes use resistive and capacitive components to achieve proper loading characteristics.

Copper conductor, Insulating polymer, Metal shielding, Ceramic substrate
