Experiments in Digital & Analog Wireless The EMONA Telecommunications Trainer, ETT-101,also known as “BISKIT” is a single board trainer which is capable of implementing many analog and digital experiments on the one unit. All that is needed in addition is an ordinary 2 channel oscilloscope or PC- based digital scope All patching leads and scope leads are included.

HOW? Build many experiments with the one trainer using a “block diagram” approach The math is expressed as a “block diagram” Students patch together the blocks The unit does not contain any pre-built experiments. Instead, it contains a select number of individual circuit blocks. Each one of these block corresponds to a block function in a block diagram. Block diagrams are used extensively in Communications & Wireless textbooks. Students simply patch together the blocks according to the block diagram. They take measurements and vary control levels to study the modulation system they have built. Building the system in this hands-on manner gives the students an opportunity to “learn by doing” as well as learn from their mistakes. Each block in the diagram has an equivalent circuit block on ETT-101 2

An example of a digital experiment with textbook-like signals Many different experiments can be built by using and re-using the same blocks in different configurations. Here we see a BPSK signal clearly, so students can understand the concepts directly. A 100kHz carrier is used to “model” an RF carrier. In this way, students can actually see the effects of modulation on the carrier. The math is the same at 100kHz as it is at 10GHz. Students can compare performance with theoretical expectations if required and explain any differences they may find. 3

Communications is constantly expanding, and new systems are built on the foundations of fundamental principles. Whilst the technologies of implementation are always changing (eg: valves, transistors, IC's, FPGA's, …) the principles remain the same. Hence, by modelling the systems at the block diagram level, students gain understanding in the fundamantal principles rather than simply how to operate current equipment. 4

Contents pages from Lab Manuals Volume 1 & 2 (Instructors manuals included) Volumes 1 & 2 cover more topics than can be covered in a typical course, so teachers can pick and choose the topics they wish to cover, and vary these at any time. The ETT-101 also has an expansion slot and users can install an optional solderless breadboard to build small circuits to work with. Expansion topics are covered in Volume 3. 5

Fully documented 'step by step' instruction with questions & worksheets All experiments are fully documented in a step by step manner. Some supporting theory is provided, and questions are included to pace the students learning. Manuals include room for measurements and act as a workbook for the student. An Instructor's manual with answers to questions is provided for convenience. One set of hard copy of all manuals, as well as soft copies (PDF) of all manuals are included, and additional hard copies can be purchased. 6
