China (Mainland) QAM Modulator

Specifications: The UMH-300 is a high-performance agile QAM modulator. It adopts digital high intermediate frequency (IF) modulating technology and achieves high performance in Modulation Error Rate (MER), Carrier-to-Noise Ratio, and Phase and Level Distortion specifications.

UMH-300 supports DS3 input and output, PSI/SI table modification and PID filtering and re-mapping.

UMH-300 QAM modulator allows digital MPEG-2 packet data to be transported through conventional CATV RF networks. ****Features**** 1)Fully DVB-C ETSI/EN 300 429 compliant 2)Supports 16QAM/32QAM/64QAM/128QAM/256QAM coding 3)Symbol rate:1.10--7.00 MS/S 4)IF output fixed on 36.125MHZ or 1--75MH tuneable 5)Provides agile RF output on frequencies between 110MHz--860MHz, minimum tuning step 0.1MHz 6)RF output level:110--118dBuv 7)ASI, DS3 input support (DS3 optional) 8)ASI, DS3 transparent loop through output support 9)DS3 to ASI transparent loop through output support 10)RF output software turn-off support 11)PSI/SI table processing and editing 12)PID segment filtering and re-mapping 13)Remote Ethernet management support 14)Online upgrading and backup support For more detailed information, please feel free to contact us right now.
