COMPACT AND FLEXIBLE, A BREAKTHROUGH IN MODERN TELECOMMUNICATIONS EXPERIMENTING Emona Telecoms-Trainer 101, known as “b i skit” A Single Board Trainer that Makes Teaching Telecommunications Much Easier for Teachers • Unrivalled with a wide range of over 29 modern communications topics in one compact trainer • Educationally well proven over many years as an excellent “hands-on” experiment system • Dynamic visual experiment method to help younger students see the relationship between math and the real world LEARNING-BY-DOING Using the ETT-101, 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. No complex math required.
With the ETT-101 students learn by trying “what-if” scenarios (and are free to make mistakes) to investigate the telecommunications theory they learn in class. With the ETT-101, your students will learn more, and remember more.
LEARNING WITH BLOCK DIAGRAMS By following telecommunications block-diagrams, students can patch the functional building blocks to implement a wide variety of basic modulators, encoders and other important “Students patch sub-systems associated with together simple telecommunications theory, building blocks using only one piece of lab hardware: the ETT-101. to make real
communications COMPACT and EASY FOR TEACHERS systems” Completely self contained within a single, low-profile case, the ETT-101 requires only a standard 12V DC plug-pack. Waveforms can be displayed on whatever equipment is available to the student, s uch as: a low cost lab oscilloscope, or a PC-based scope, or a standard PC Sound Card with the optional Sound Card Interface box and software. The ETT-101 accessories kit includes: 20 x stackable patch cords, User Manual, Experiments in Modern Analog and Digital Telecommunications Volume-1 and a 12V plug pack.

EMONA Telecoms Teaching Range The Emona Telecom’s-Trainer 101, ETT-101, is one of a number of Emona’s specialist telecoms laboratory teaching tools. The EET-101 is designed for technical college and high school labs where telecoms is first introduced. The ETT-101 is a low cost unit to cater to large student numbers who need to gain a “handson” appreciation of telecoms theory at a simple, introductory level. Also displayed in the diagram are Emona’s the other trainers and modeling systems.
“The ETT-101 will build the student’s confidence and appreciation for math & theory”
WHAT TOPICS CAN THE ETT-101 TEACH? TELECOMMUNICATIONS TOPICS • Basic Analog Communications AM, FM, DSB, SSB, PM, PAM, TDM, PWM, Superheterodyne, Speech in Comms, PLL, QAM, SNR Concepts and more
• Digital Communications PCM, PCM-TDM, ASK, BPSK, FSK, GFSK, Eye Patterns, DPSK, QPSK, Spread Spectrum, Line Coding, Noise Generation, SNR Concepts and more
BASIC ACADEMIC CORE SKILLS • Thinking Skills Problem solving activities, evaluating evidence, interpreting instructions, analysing evidence and drawing conclusions.
• Science Skills Measurement, experimental procedure, system building, electricity and waveforms.
• Math Skills Mathematical operators, equations, trigonometric functions, continuous and sampled functions, charts and graphs, positive and negative values.
LABORATORY MANUAL The ETT-101 Laboratory Manual (Vol.1) provides a turn-key solution for the teacher and student alike.
The lab manual is specially written to guide younger students through handson 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”, the “101” 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.
