The DTU-331 is an all-band, all-standard SDR receiver based on a dual tuner architecture. A satellite tuner with a 9..60MHz bandwidth enables reception of DVB-S signals, while a second tuner with a bandwidth up to 8MHz adds support for terrestrial and cable standards. A front-end, with an optional RF mixer in the path, allows down-mixing of terrestrial/cable signals located in the L-band before being fed to the 8MHz tuner. The same RF mixer can also be used to downmix satellite signals in the S-band back to the L-band frequencies, so that they can be received with the 60MHz tuner.
The output of the tuners is converted to 16-bit IQ-samples with Analog-to-Digital converters and passed through a low-pass filter and a sample rate converter, which helps to clean up and prepare the signal for processing. At this stage, the IQ samples can be demodulated with the SDR demodulation software in the DekTec SDK (DTAPI) or alternatively, they could be recorded to disk or read into your own SDR application.
