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.
What is Software Defined Radio?
SDR, or software-defined radio, is a technology that allows a radio receiver to be reconfigured through software rather than requiring physical changes to its hardware. This makes SDR receivers, such as the DTU-331 and DTA-2131, highly versatile and adaptable to a wide range of applications. For a more detailed description about SDR please refer to the following Wikipedia page.
DTU-315 – All-standard 0-2GHz modulator for USB-3
The DTU-315 is a USB-3 modulator counterpart for the DTU-331. Buy a set to have the ultimate portable RF test signal tool-set for use in the lab or in the field.
DTA-2131 – Multi-standard cable/terrestrial receiver for PCIe
The DTA-2131 is a multi-standard VHF/UHF receiver for PCI express utilizing SDR technology.
Basically, a PCIe equivalent of the DTU-331, but more suited for static lab or monitoring setups.
