Manuals and Course Material



The ETT-101 Laboratory Manuals (Volumes 1 and 2) provide a turn-key solution for the teacher and student alike.

The manuals are 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', the '101' Lab Manuals make 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.

The ETT-101 User Manual contains brief descriptions of each block function on the unit, its specifications and operating instructions. Students only need refer to this manual upon beginning a course, after which time using the system becomes easy and intuitive.

Compact and Easy For Teachers

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.

The ETT-101 accessories kit includes: 20 x stackable patch cords, User Manual, Digital and Analog Basic Telecommunications Experiments Manuals Volumes-1 & 2, and a 12V plug pack.
