Single-tipped probe for analyzing tri-state logic systems, etc.; has ac signal termination and RCR filter

摘要

The probe has a tip resistance, one end of which is connected to the probe tip. One end of a cable is connected to the tip resistance and the other end is connected to an AC signal termination which is coupled to ground. An RCR filter is connected to the AC signal termination. The circuit typically includes a digital to analog converter (DAW) and an analog to digital converter (ADW).
