Product Specification

trainer kit : advanced communication lab

Product Description

(1) Advanced technology: adopts development platform of “DSP+FPGA”, to realize digital base band transmission system, digital frequency band transmission system, digital programmable control switching system, CDMA mobile communication system as well as analog modulation system, and etc. 

(2) Powerful function:speech coding technology, base band transmission technology, multiplex technology,  analog modulation and demodulation technology, digital modulation and demodulation technology, synchronization technology, error-correcting code technology, interface technology, spread spectrum technology, duplex technology and exchange technology and etc. 

(3) Advanced structural design: adopt embedded modularization design. All modules are uniform size, flexible structure, and convenient upgrade. Users could choose the modules by requirements.   

(4) Abundant secondary development experiments:  includes unit and system experiments, and also experiments for secondary development and courses design. It has four specialized secondary development module: SCM, CPLD, DSP and ARM secondary development modules, which could offer 41 secondary development experiments all together. 

(5) Combination of hardware and software: students emulate and calculate data or waveforms by software, such as QuartusII, Keil, CCS, ADS1.2 and etc, then physical verify, finally develop by their own. 

(6) Seperate innovative experiment module: GPRS and wireless transceiver modules, which could complete design and application experiments.

(7) Adopt plexiglass baffle for protection
