communication principle experimental box

Quick Detail

Package & Delivery Lead Time

Detailed Description

This experimental system is paying attention to communication systems. Its knowledge points cover a complete communication process such as information source coding and decoding technology, channel decoding techniques, digital modulation & demodulation technology, digital multiplex technology, and synchronous system of extracting technology. And it use various realization for important technology. The greatest characteristic of the experimental system is using CPLD/FPGA platform to finish all the experiments. This system have expanded two secondary development modules, which make the function of experimental system improving from confirmatory to confirmatory and designable experiment. These improvements ask the students to use their heads and hands to do experiments, and improve their ability of how to do and how to solve the problem. It can satisfy the high school’s required. Main Technical Indexes: Simulated signal source: sinusoidal signal: f=20Hz～1MHz Vpp=0～20V square-wave signal: f=20Hz～1MHz Vpp=0～20V triangle wave: f=20Hz～1MHz Vpp=0～20V Digital signal source: time signal: 1.024MHz 512KHz 256KHz 128Hz 64KHz 32KNz 16KNz 8KHz synchronous signal: 8KHz pseudorandom code: 3KHz Regulated DC power supply: ±5V ±12V 0～15V Frequency meter: 100Hz～2MHz Sensitivity≥100mV
