QAM Trainer
Order Code: 40538
Category: Communication Trainers
QAM trainer is developed to help engineers understand the concept of merging the techniques of Phase Shift Keying (PSK) and Amplitude Shift Keying together to form Quadrature Amplitude Modulation (QAM) allowing the increase of dat...
SPECIFICATION
The QAM trainer allows the users to study the waveform generated during different stages of QAM modulation and demodulation. The extra user friendly, facility of user satiable trigger allows the user to search a particular bit. Pattern easily on the data sequence and view the waveform generated by it, making learning easier.
The onboard noise generator allows the user to generate noise of varying levels in the demodulator inputs and see their effect in the output of the demodulator.
Additional pins for constellation view are provided on the board for easy study of constellation diagrams of both modulator and demodulator.
- Data Speed : 15625 bits/sec.
- Data Format : Synchronous
- Data Sequence : 24 bit user selectable via on board de-bounced DIP switches.
