An information collecting apparatus and an information collecting/analysing system which may be a logic analyser

摘要

An information collecting apparatus and system using an external host computer that enable measurement over long periods of time without a built-in large capacity storage device are provided. The information collecting/analyzing system (10) comprises an information collecting apparatus (20), including an input unit (21) for sampling digital signals input from each part of an object to be measured, a transfer unit (23) for transferring the digital signals via a communication interface (12) to a host computer (30) in substantially real time, and a control unit (24) for controlling the input unit and transfer unit; and a host computer, including a signal processing unit (32) for processing digital signals transferred from the information collecting apparatus, a storage device (33) for storing processed digital signals in substantially real time, display units (34, 35) for displaying various types of images based on digital signals stored in the storage device, and a control unit (36)for controlling the signal processing unit, storage device and display units.
