LOGICAL SIGNAL INDICATING METHOD IN A LOGICAL SIGNAL DETECTOR

摘要

Logic signal measurement apparatus has a memory for storing logic signals, a part of which can be selected for display, at a controllable magnification, simultaneously with an indication of the relationship of the selected part to the rest of the logic signals. Preferably, the indication is a bar consisting of black and white zones along its length which represents the entire memory capacity. An indication of the trigger point may also be provided. The logical states of the elements in the parallel memory channels (eight) corresponding to the white part of the bar are displayed in lines 0-7.
