Description
|
Building on the proven Airspy HF+ architecture, Airspy have designed the Most Refined HF/VHF SDR with world-class performance in the smallest form factor. Both the architecture and level of integration achieved in this design allow Airspy to bring top-performance reception at a very affordable price.
The Airspy HF+ Discovery sets a new standard in terms of reception performance with extra pre-selectors for all the supported bands and a New DSP Core to optimize the gain distribution and the filtering parameters in real time and dig deeper into the noise. |

The signal path includes very high dynamic range data converters along with high-performance passive mixers with an excellent Polyphase Harmonic Rejection structure. The included band-tracking pre-selectors eliminate unwanted interference and preserve the dynamic range of the receiver. With its world-class strong signal handling capability and incredibly Low Noise, the HF+ Discovery is the ideal companion for all your High-Performance Receive Scenarios.
