DTMB Lab Modulator

LabMod-DTMB modulator provides a complete, cost effective solution for Chinese DTTV network setup in a lab or manufacturing environment, cumulating rich inputs / outputs interfacing offer, as well as internal stream player, advanced test modes and optional Channel Simulator.

LabMod-DTMB is fully DTMB Chinese standard compliant (GB20600-2006), and offers several kinds of inputs (ASI or USB). It generates high quality RF or IF signals that will fit any test situation that may occur in a lab, research and development, or manufacturing site.

Remotely manageable thanks to an embedded HTTP web server, LabMod-DTMB modulator has a high set of features for RF and IF corner testing such as carriers cancellation, interleaver bypass, very large output level range, etc...

• FPGA based HW for robustness and
  reliability
• Over 42dB MER in RF mode (over 44dB in IF mode)
• ASI and USB inputs
• RF output (100 to 870MHz) with very large output level range
  (-60 dBm to +2dBm)
• IF output (20 to 85MHz)
• MFN transmission capable
  (bit rate adaptation, PCR restamping capable)
• Special test modes
  (PRBS insertion, carriers removal, test tone, guard interval setup, white noise generation and C/N mastering)
• 10MHz input and output
• Modulation settings can be saved as Profile
