Optimizing Oscilloscope Measurement Accuracy on High-Performance Systems with Keysight Active Probes
應用說明
This application note covers the following information that you should consider when selecting an oscilloscope probe to capture high-speed signals: Consider the effect that probe input impedance will have on your circuit. Capacitive loading becomes increasingly important at high frequencies and it is important to use the shortest possible ground lead to minimize inductance. The probe will introduce distortion into your measurements unless it has a flat transmitted response throughout the bandwidth of the probe. A flat transmitted response will closely track the signal at the probe tip and pass it to the oscilloscope with minimal degradation.
