Compact Experimenter – BiSKIT 101


Using the expertise from many years of manufacturing telecommunications teaching equipment, Emona is now offering the Emona Telecoms-Trainer “ETT101”. The ETT-101 is designed for introductory university courses and technical college labs where telecommunication is first introduced. The ETT-101 is a low cost unit to cater to large student numbers who need to gain a ‘hands-on’ appreciation of telecoms theory at a simple, introductory level.

Building Student Knowledge in Technology is what our equipment is all about, and so the ETT- 101 is also known as ‘BISKIT’, easy to say and easy to use.

The Emona Telecoms-Trainer 101 (ETT101) is a single board trainer that makes teaching telecommunications much easier for professors in introductory university and technical college courses.

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, such as: a standard lab oscilloscope, or a PC-based scope. This dynamic visual approach helps students to see the relationship between modern telecoms methods and the math. The ‘hands-on’ approach builds student confidence and makes the experiment satisfying as the students are free to explore and learn by making mistakes. When they explore more, they learn more
