Model: CIET-EC
ELECTRONICS COMMUNICATION
OBJECTIVE:
To conduct experiments on analogue and digital communication techniques by log in real time signals through DAQ card to a personal computer and observing outputs on PC scope.
INTRODUCTION:
The LAB ELECTRONICS CIETEC is designed to help the students to understand the basic concepts of Electronics Communication (Analogue and Digital Communication). Students can conduct experiments through a PC. They can learn to log the real time data through DAQ card and outputs can be observed on the PC Scope by connecting CIET trainer to a PC through USB DAQ card.
