KL-920

The KL-920 kit is equipped with high-speed MCUs and DSPs and high-flexibility FPGAs, giving students more opportunities to build circuits and observe digital data signals of each transmission stage.The kit supports the study of a variety of telecommunications concepts, including: ASK / FSK transmi-sion in the ISM band of radio communication, FEC coding techniques (block and splice code), digital data formatting (preamble, ID, FEC and CRC), Manchester coding, SONET transport frame (STS-1 and STM-1), TDMA, PCM, TDM, DSSS and CDMA modulation, digital filters, etc.

Characteristics

• Complete digital transmission data format including start bit, preamble, identifier, FEC encoded data, CRC encoding and stop bit.
• All digital transmission data are encoded with Manchester code before transmission by ASK or FSK modulator.
• Programming of data, modulation rate, preamble, ID and noise with DIP switches.
• FEC coding, CRC mechanism and Manchester coding can be applied or ignored before ISM wire-free transmission.
• Transmit and receive 3 sets of acoustic signals in TDMA ka-nal via STS-1 and STM-1 frames.
• Two-channel TDM transmission of PCM modulated audio signals or via a compander with A-Law/μ-Law characteristics.
