DAR-2000A
Digital TV Exciter for Single-Frequency Network
DAR-2000A is an exciter for single frequency network repeaters based on the ATSC1.0 standard.
The DAR-2000A is a co-channel interference noise cancelling regenerative repeater, and more specifically, a co-channel interference noise cancelling regenerative repeater of the Advanced Television Systems Committee (ATSC).
Function
Signal Measurement
- Measurement of transmission signal quality: SNR, EVM, IMD, etc.
Signal processing and calibration
- Interference Cancellation System (ICS)
- Adaptive pre-corrector: Compensation of linear and nonlinear pre-distortion
- Demodulator Integrated
User Friendly
- Save logs for alarms and faults
Short system delay time
- Secures reception stability in the same channel network
