| Product overview
KSW-HDR600 high-bit rate receiver receives high-bandwidth and high-rate signals from space satellites in real time. The signal receiver demodulates and analyzes the signals and then forwards the data to the back-end server for processing through the high-speed optical fiber interface.
KSW-HDR600 high-bit rate receiver has the function of simultaneous processing of signals received from two channels, supporting multiple intermediate frequency points such as 720 MHz, 1.2 GHz, 1.5 GHz, 2.4 GHz, etc., and can be equipped with frequency converters as required to support signals in Ku, Ka, C, X and other bands. It provides several demodulation methods such as BPSK, QPSK, OQPSK, UQPSK, DQPSK, GMSK, 8PSK, 16QAM, 16APSK, 32APSK, etc., and provides several basic functional modules such as carrier capture, tracking, symbol synchronization, RS encoding and decoding, convolutional encoding and decoding, LDPC encoding and decoding, frame synchronization and bit error testing.
KSW-HDR600 high-bit rate receiver has the functions of constellation map display, spectrum measurement and display, EVM measurement, phase error measurement, amplitude error measurement, SNR test, gain balance and so on.
KSW-HDR600 high-bit rate receiver has completely independent intellectual property rights and excellent performance, and can provide customized development services according to user requirements.
