DTU-215 - Cable/Terrestrial Modulator for USB-2  


Cable/Terrestrial Modulator for USB-2

The DTU-215 is a portable modulator for terrestrial and cable standards. By it's USB powered design and a comprehensive channel-simulator, including AWGN and Multipath echo, it is a true fully-featured and easy-to-use multi-standard modulator for demonstrations and R&D.

The DTU-215 has been discontinued and is no longer being manufactured. For new projects, DekTec suggests opting for the DTU-315.
