Abstract
An improved probe for probing high speed, low impedance bus structures. The probe comprises an AC termination portion and an RCR filter. In a first embodiment, the AC termination portion comprises a resistor and capacitor in series. The time constant formed by the AC termination portion is sufficiently larger than the time it takes a signal to travel through the cable of the probe. The RCR filter comprises two resistors in series disposed between the AC termination resistor and ground. A capacitor is connected in parallel to the first resistor in order to achieve a flat pulse response from DC through to high frequencies.
