Modulation and Coding Workboard 53-230

Part of Analogue & Digital Telecommunications Workstation 53-004

Modulation and Coding workboard 53-230 is a fully-featured, complete, laboratory course covering the principles of operation and the practical implementation of modern modulation systems required for both analogue and digital communication systems.
The close integration of the hardware workboard with computer-based instruction and instrumentation software provides the student with a rich learning environment and the tutor with a cost-effective solution to this field of telecommunications teaching.
Practicals are configured by patching together circuit blocks, which are shown step-by-step in the software.
The workboard connects to a personal computer via a USB Real-time Access Terminal (92-200 RAT) which is a fast Analogue-to-Digital converter, sampling signals on the workboard at rates from 10 to 100MHz, as required. The Terminal also provides all the necessary power supplies for the workboard.
