DAR-1000H
Digital TV Repeater
The DAR-1000H is a DTV repeater equipped with the function of modulating SMPTE 310 or ASI standard signals into 8VSB signals and conversely demodulating terrestrial 8VSB signals into SMPTE-310 or ASI standard signals.
The DAR-1000H’s Adaptive Corrector function automatically compensates for linear and nonlinear distortion to maintain optimal signal quality.
DAR-1000H receives feedback on the transmission signal and measures and displays the quality of the transmission signal.
Function
Signal Measurement
- Measurement of transmission signal quality: SNR, EVM, IMD, etc.
Signal processing and calibration
- Adaptive pre-corrector: Compensation of linear and nonlinear pre-distortion
- Integrated exciter with demodulator
Remote Control
- Wireless remote control: Ethernet, CDMA
