Emona Telecoms-Trainer ETT-202
Multi-Experiment Single Board Telecommunications Trainer for the popular NI ELVIS™ Platform
DATEx : Digital Analog Telecommunications Experimenter
COMPACT AND FLEXIBLE, A BREAKTHROUGH IN MODERN TELECOMMUNICATIONS EXPERIMENTING
Emona Telecoms-Trainer 202, known as DATEx Plugs into the NI ELVIS™ platform, operating in local mode and under LabVIEW™
•An excellent “ hands-on” experiment system, implementing the well established “block diagram approach” to building telecommunications experiments
•Unrivalled with a wide range of modern communications topics in one compact trainer
•Local control and also remote control via the ETT-202 SFP virtual instrument on LabVIEW™
DESIGNED FOR NI ELVIS™ The Emona Telecoms-Trainer 202 extends the functionality of your NI ELVIS™ platform and LabVIEW™ software with a plug and play telecommunications board to teach the fundamentals of modern communications theory.
Waveform displays and measurements are on-screen using LabVIEW™. Control is either via the front panel knobs and switches, or through the PC via the ETT-202 Soft Front Panel (SFP) instrument.
Using the ETT-202, students learn fundamental concepts by actually building telecommunications experiments at the block diagram level. Theory comes to life as they build the modulation and coding schemes in carefully guided steps.
- Students are free to learn by trying “what-if” scenarios to investigate the telecommunications theory they learn in class. With the ETT-202, your students will learn more, and remember more.
COMPACT and EASY FOR TEACHERS The system is completely self contained: all that is required is the ETT-202, NI ELVIS™ and LabVIEW™ running on a PC.
- The ETT-202 accessories kit includes:
20 x stackable patch cords, User Manual, Digital and Analog Basic Telecommunications Experiments Manual Volume-1 and the ETT-202 SFP CD-ROM.
ADDITIONAL EXPERIMENT CAPABILITIES
Given that the ETT-202 provides a wide array of fundamental electronic building blocks, controllable using LabVIEW™ , the ETT-202 can also be used as a general purpose applications board to investigate topics such as systems control and integration of LabVIEW applications with electronic hardware.

LABORATORY MANUAL
The ETT-202 Laboratory Manual (Vol.1) provides a turn-key solution for the teacher and student alike.
It is specially written to guide students through hands-on experiments and help them grasp the fundamental concepts of telecommunications.
Each chapter includes background information which relates the experiment content to real-world applications.
Since telecommunications text books represent the math and concepts of telecommunications theory as “block diagrams” this Lab Manual makes extensive use of block diagrams throughout. Associated with each block diagram are detailed, step-by-step patching diagrams. Each chapter is carefully paced and constant use is made of questions to verify the student's understanding and provide feedback to the teacher.
