DTV Signal Generator
DSG500 >
Overview
DSG500 is the all-in-one DTV signal generator supporting MPEG2 TS and RF Signal generation in one unit. It can cover all
DTV standard in one unit including DVB-T, DVB-C, ATSC ,OpenCable, DVB-S/S2, DMB-TH and ADTB-T.
Most importantly,
importantly DSG500 supports multi signal output (Max
(Max. 2 RF) in one unit that allows to use signal simultaneously
simultaneously.
It will save your cost and time for buying several other DTV signal generators.
