DAR-1000B
advanced Digital TV Exciter for Multi-Frequency Network
The DAR-1000B is an improved DTV Adaptive Exciter that converts received UHF band DTV signals into STMPTE-310 or directly receives TS input and performs 8-VSB modulation and UHF RF channel conversion.
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
- Demodulator integrated
User Friendly
- Generating signals for performance testing
- Save logs for alarms and faults
