£843.00 £1,011.60

This unit is a combined COFDM, QAM & ATSC Modulator with VHF & UHF Upconverter. The high speed USB 2.0 bus allows for a 20Mb software buffer, and the product itself works excellently with Windows XP, Vista, Windows 7 & Windows 10 Drivers + SDK & Linux Drivers. All of the modulation processes are carried out by the hardware so that there is no load on the PC processor. As a result, there is no need for an expensive, high-performance PC.
