A single box tester allows for simultaneous testing of digital video and digital communications capabilities of a device under test. An arbitrary waveform generator is used to generate a test signal suitable for testing DTV receivers operating using standards such as DVB-H or T-DMB, while simultaneously a test signal generator and receiver allow testing of communications capabilities of the device using standards such as EGPRS, GSM/EDGE-(GSM900, GSM1800) or WCDMA.
