Performance and application of ETC compact TV signal analyzer

ETC compact TV signal analyzer provides a complete measurement function for DVB-T2, DVB-T / DVB-H and ISDB-T digital TV transmitter. It is also used in TV transmitter services and maintenance, as well as testing modulators in R & D and quality assurance environments. The design of this analyzer is ideal for overlay measurements in radio television network planning. ETC focuses on TV signal analysis and can also perform spectrum and scalar network analysis and power measurement. In addition, users can perform tests that require higher sensitivity and selectivity by activating their built-in pre-pre-selected pre-selected presence. The core component of the ETC is an FPGA-based real-time digital TV demodulator, which optimizes real-time BER measurement and outputs the demodulated MPEG-2 transport stream through the ASI port. The instrument also provides a comprehensive range of transmitter measurements, including amplitude, phase, and group time delay in DVB-T2, DVB-T, and ISDB-T. Another advantage of the compact television analyzer is its high speed measurement and the number of rapid start and mode switching, which greatly reduces the time required for testing. In order to facilitate data exchange and monitoring, the instrument comes with Windows-based PC software ETCVIEW, allows the user to record measurement results. Data can be transmitted via USB or LAN interface. main feature: • Support DVB-T2, DVB-T / DVB-H and ISDB-T digital TV standards • Up to 3.6 GHz or 8 GHz wide frequency range • Real-time precision MER measurement (typical value 44 dB, 500 MHz) • Quasi-error-free transmission stream decoded wide input level range (-76 dBm to +10 dBm) • Typical value -165 dBm (1 Hz) spectrum analyzer displays average noise level (DANL) • Comprehensive analysis of digital signal transmission • Support MPEG coding and analysis • Easy to operate, network coverage analysis and automatic test measurement Editor in charge: GT, read full text
