DAR-1000A
Digital TV Exciter for Multi-Frequency Network
Not only DAR-1000A directly converts the SMPTE-310 or ASI standard signals into the 8VSB signal, but also re-transmits different frequencies with the demodulation function which converts the terrestrial 8VSB signal into the SMPTE-310 or ASI standard signals.
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
