USB box

USB boxes are black boxes that perform certain functionalities. They are used as receiver and converter units in combination with notebooks and personalcomputers. Their functionality can be related to the reception and processing of digital TV or digital radio, but also to the conversion and processing of measurement signals.

  1. USB boxes designed for digital TV can receive digital television with terrestrial broadcasting, DVB-T, with satellite broadcasting, DVB-S, or programs transmitted via broadband cable, DVB-C. They are functionally similar to set-top boxes, as they, like them, can be equipped with an interface for Common Interface( CI) and thus can also receive decrypted television.

  2. A similar approach is used in measurement technology, where a USB box can perform the functions of an oscilloscope, spectrum analyzer, voltmeter, function generator or transient recorder. There are also versions with which protocols can be analyzed.
