Logic Probe Adopts Two Comparators

Published:2011/8/25 5:25:00 Author:Amy

Measurement instruments should not affect the circuits. For instance, a logic probe must suitably detect logic levels, and it should not put undue loads on the test circuit. The logic probe must set thresholds on automatically checking logic levels, relying on the supply voltages of the ICs it is checking. The previous logic probe has loading problems (Reference 1). Its thresholds do not adequately depend o...   (View)
