Description: The Amitec Digital Radar Training Lab, Model DRT04, is a complete, state-of-the-art, digital communications training system, including all the instruments required to perform the experiments.

Specially designed for hands-on training, this system facilitates the study of many different types of Analog & Digital modulation/demodulation technologies such as PAM, PWM, PPM, PCM, Delta Modulation, ASK, FSK, and BPSK as well as spectrally efficient technologies such as QPSK, QAM, and ADSL. All the experiments are performed at baseband and RF frequencies for a real feel of practical system. Advanced communications technologies such as CDMA are also covered. The system is designed to reflect the standards commonly used in modern communications systems.

The system is based on a reconfigurable hardware training platform and an open source communications technology software. This approach allows for tremendous flexibility at a reduced cost. Each of the communications technology to be studied is provided as an application that can be selected from the menu. The hardware is self configurable upon connecting to mobile workstation provided.

The selected application configures the hardware platform to implement the communications technology physical layer and presents a specially-designed user interface for the student.

In analog system, it can implement on air transmission & reception of Analog modulation & demodulation techniques like AM, DSBSC, SSB, Narrowband FM, Wideband FM, Stereo FM and others.

In digital system, it can implement on air transmission & reception of Digital Modulation & Demodulation techniques like ASK, FSK, BPSK, DBPSK, MSK, GMSK, DQPSK, QPSK, OQPSK, pi/4QPSK, 8PSK,16QAM, 64QAM, 256QAM, CPFSK, GFSK, and other variants.

The USB 3.0 super speed interface serves as the connection between the ADC04 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.

ASIC houses complete RF and DAQ subsystems on a single board. 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 is provided with Linux Ubuntu pre loaded and tested with platform for repeatable performance and no surprises. The list of experiments is growing by the day to include most modulations as per international curriculum.

The courseware consists of a series of student manuals covering different technologies as well as instructor guides that provide answers to procedure step questions.

The Digital Radar Training Lab and the accompanying courseware provide a complete study program for these important technologies.
