SATELLITE COMMUNICATION TRAINING LAB SCT04

Description:

The Amitec SCT04 is a software programmable hardware transceiver which allows limitless satellite communication laboratory experiments to be performed on a single device. The entry barrier is lowered to include the under graduate students by providing a graphical programming environment. The burden on faculty is lowered by using courseware designed at Amitec from simple FM to most complex Modulation techniques. Lab technicians are eased by integrated hardware and software from same source for trouble free performance.

The system is ideally suited for applications requiring high RF performance and great bandwidth such as physical layer prototyping, dynamic spectrum access and satellite spectrum monitoring.

The Superspeed USB 3.0 interface at 5Gbps serves as the connection between the SCT04 LAB and the mobile workstation. This enables the user to realize 40 MS/s of real-time bandwidth in the receive and transmit directions, simultaneously (full duplex). FPGA is autoloading so hadrware is plug and play as a pen drive! No need to program the FPGA for most cases!

The systems offers high bandwidth and dynamic range. One unit is earth station transceiver and other unit is satellite link emulator connected to realize a satellite link. External PPS and reference inputs can also be used to create larger multi-channel systems.ASIC houses complete RF and DAQ subsystems on a single board. Coupled with these benefits it hosts onboard RF Transceiver subsystems capable of tuning frequencies from 400MHz to 4GHz.

For ease of usage Core i3, USB 3.0 Mobile Workstation/Note book Computer provided with Linux Ubuntu pre loaded and
