8-VSB Modulator
DVM-1903ML

AS a 8-VSB modulator, it is a professional performing product based on the 8-VSB(ATSC) modulation. It shows superior quality to modulate MPEG transport stream as DVB-ASI signal to 8-VSB(ATSC) and output as suitable frequency band for digital broadcasting transmission. Also, it is very easy to control with high class front VFD.
