Bit error rate (BER) can be measured at different points on set-top boxes for digital television. A BER instrument must be able to accept and evaluate data in serial or parallel form or as the payload of an MPEG2 transport stream. This is no problem with TV Test Transmitter SFQ and its BER measurement option: while the necessary signals are generated at the right places in the signal flow, BER is measured at the same time. Together with an optional noise generator and fading simulator, SFQ is also able to simulate the interference occurring in real-life transmissions in a reproducible way.
