Agos is growing with the company and its customers
Digital TV Signal Receiver is a signal analyzer that receives ATSC 3.0 signals in IF and RF band through demodulation and decoding. Digital TV Signal Receiver tester can receive most of ATSC 3.0 PHY standard signal based on LDPC channel coding and LDM multiplexing technology, and it is more smooth with additional functions such as video data transmission through IP, DM function through GUI and RX signal loading Provides a test environment
Key Features
Provides a smooth signal analysis environment through FPGA-based real-time demodulation and easy to update by simply implementing new standards
