LOGIC SIGNAL MEASURING DEVICE

PROBLEM TO BE SOLVED: To provide a logic signal measuring device setting automatically in a short period of time, the optimum threshold in each measuring channel, when a logic probe detects an unknown logic signal. SOLUTION: This logic signal measuring device constituted so that a logic signal comprising a plurality of bits as a measuring object, is taken through a probe having a comparator and displayed on a display part, is provided with a threshold setting means for setting a threshold of the comparator by detecting a level changing point of an output signal from the comparator, while changing the threshold of the comparator automatically for every prescribed amount in the direction of an H-level and an L-level.
