Abstract
A logic analyzer which can simultaneously measure one block of input data in detail and the same or another block of input data in rough form is disclosed. The logic analyzer comprises first and second sections each including a memory circuit to store the input data and a word recognizer to detect the desired trigger word from the input data. These first and second sections receive different clocks having different rates, and the second memory circuit stores the first clock applied to said first section for recognizing the time relationship of these clock signals. A counter counts the first clock in accordance with the outputs from the first and second word recognizers for recognizing the time relationship of the first and second trigger words.
