The project and implementation of an upconverter for the DVB-T signal

DVB-T is becoming the most popular standard of terrestrial video transmission. The number of devices working in this standard is growing; therefore developing methods and measurement set-ups enabling testing entire devices as well as their sections is reasoned. In the present paper there has been shown a project and test results of a system, which's aim was to transmit the DVB-T signal in any frequency channel in the range of 470–870 MHz. The system is supposed to be a core of automated DVB-T measurements setup and consists of the DTA-116 TV card and the constructed device, which is a low-cost alternative for the commercial solutions. The upconverter was designed, realized in PCB technique and tested experimentally.
