<p>The device enables to analyze the faults of a computer allowing to detect the not operating parts of the circuit. The device consists of an electronic card (1) with analog-to-digital combined circuitry. The card communicates with the under testing electronic (3) through the control of the signals presented on the connectors of the system channel (9) and of the signals of the power connector (11). Characteristic of the device is to control the activities of the testing system with outer control of functional parts. Integrating part of the device is a portable computer (2) connected with the diagnosis card by means of serial interface (6) used for input programs on diagnosis card (1) and for display test results on own video (17) and the print on a connected printer (16). The device is foreseen with separate power (8) to have a proper operation and also to allow the detection of troubles on the system power supply (10).</p> |
