![]() ![]() The frequency range is highly dependent of the used tuner, dongles that use the Elonics E4000 offer the widest possible range (see table below). A stable sample-rate of 3.2 MS/s without lost samples is only possible with the Etron EJ168/EJ188/EJ198 series of host controllers due to their specific maximum latency. The RTL2832U outputs 8-bit I/Q-samples, and the highest theoretically possible sample-rate is 3.2 MS/s, however, the highest sample-rate without lost samples that has been tested wit regular USB controllers so far is 2.4 MS/s. Antti Palosaari has not been involved in development of rtl-sdr. The possibility of this has been discovered by Eric Fry ( History and Discovery of RTLSDR). DVB-T dongles based on the Realtek RTL2832U can be used as a cheap SDR, since the chip allows transferring the raw I/Q samples to the host, which is officially used for DAB/DAB+/FM demodulation. ![]()
