DAR-1100T
Digital TV Exciter for DTV Transmitter(MFN)
The DAR-1100T is a DTV Adaptive Exciter for high-power transmitters that converts received UHF band DTV signals into STMPTE-310 MPEG TS (Transport Stream) signals 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
