Analogue Communications Trainer
Multiple access technique (at least 1) in analogue communication systems should also be covered. Interfaces (for communication with a computer if present): GPIB USB 2.0 (or higher) or Ethernet. The trainer should also have points on each of the sections/components of the communication system for displaying the signals. Should cover different analogue modulation and demodulation techniques for each of amplitude (with at least any two of single sideband (SSB), double sideband (DSB), and Vestigial Sideband), phase (narrowband angle) and frequency (wideband). Power Supply: 240V, 50-Hz, power cable with 3-pin plug.  Should come with software (compatible with windows 7) for simulation of analogue communication systems and detailed analysis of block diagrams and circuit diagrams for each of the sections for the system.
