Introduction

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.
