La caracterización de un dispositivo consiste en la medición de pares ordenados (tensión, corriente) para el trazado de curvas de corriente en función de la tensión (característica I-V). El hardware del sistema consta de: un circuito acondicionador de señal y de excitación, una fuente de alimentación, una Tarjeta de Adquisición de Datos (TAD) y una computadora personal a la que se conectan diferentes equipos clientes a través de una red TCP/IP. El software es un instrumento virtual programado en LabVIEW 2015 y se ejecuta en la computadora. Mediante este se realiza el procesamiento de las señales asociadas a los dispositivos, adquiridas a través de la TAD, para la posterior presentación de los resultados. La programación realizada permite la ejecución y configuración del instrumento virtual de forma remota mediante una interfaz web. Se incluyó la posibilidad de salvar a la computadora del usuario los resultados de las mediciones como un fichero de texto. Para la validación del sistema, se compararon mediciones de diferentes dispositivos de dos terminales con sus valores teóricos y datos experimentales brindados por sus fabricantes.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT This paper presents the design of a remote virtual instrument, hardware-software set, used for the characterization of two-terminal electronic devices, such as resistors and diodes, with remote access capability. The characterization of a device consists of measurement of ordered pairs (voltage, current) for drawing current curves as a function of voltage (I-V characteristic). The hardware system consists of: a conditioning and excitation circuit, a power supply, a Data Acquisition Board (DAQ Board) and a personal computer to which different client computers connect through a TCP/IP network. The software is a virtual instrument programmed in LabVIEW 2015 and runs on the computer. This program performs the signal´s processing associated to the devices, acquired through the DAQ Board, for the subsequent presentation of the results. The programming made allows the execution and configuration of the virtual instrument in a remote form through a web interface. The possibility to save measurement results at the user´s computer as a text file was included. For the system´s validation, different measurements of different two-terminal electronic devices were compared with its theoretical results and experimental data provided by their manufacturers.]]></p></abstract>
