类型:电视信号发生器 品牌:tlw 型号:tvb595 频率:50-2150（MHz） 电平:0dbm（V） 外形尺寸:15*25（mm） 重量:2（kg）

Overview
The U* di*al streaming DTV modulator can play MPEG stream from hard disk and DVB-ASI/SMPTE-310M
input into on-air signal. The output can be industry standard 55~956MHz and 956~2150MHz selectable RF signal.
On board synthesizer can generate stable and accurate symbol clock and tuning frequency. The transport
stream can be supplied through U* interface and DVB-ASI/SMPTE-310M input.
Features
• Transport stream from hard drive thru U* interface and DVB-ASI/SMPTE-310M input
• DVB-ASI, SMPTE-310M output for monitoring
• On board VHF/UHF/L-BAND RF output up-converter
• Programmable RF output level (0.1dB step)
• Superposition white noise over modulated signal and control the output C/N ratio
