Description
The SDRplay RSPdx-R2 is a wideband full featured single-tuner 14-bit SDR receiver which covers the entire RF spectrum from 1 kHz to 2 GHz giving up to 10 MHz of spectrum visibility. It contains three antenna ports, two of which use SMA connectors and operate across the full 1 kHz to 2 GHz range and the third uses a BNC connector which operates up to 200 MHz.
The RSPdx-R2 is an enhanced version of the RSPdx with further design improvements for use at frequencies below 2 MHz. Housed in a strong steel case, in addition to the functionality of the RSP1B, the RSPdx-R2 provides three software selectable antenna inputs and an external clock input. It offers excellent performance through HF and VHF frequencies all the way up to 2 GHz. The RSPdx-R2 also supports an "HDR mode" optimised for the demanding radio reception conditions below 2 MHz.
The RSPdx-R2, when used in conjunction with SDRplay’s own software, introduces a special HDR (High Dynamic Range) mode for reception within selected bands below 2 MHz. HDR mode delivers improved intermodulation performance and fewer spurious responses for those challenging bands.
Features
- Covers all frequencies from 1 kHz through VLF, LF, MW, HF, VHF, UHF and L-band to 2 GHz, with no gaps
- Receive, monitor and record up to 10 MHz of spectrum at a time
- Significantly improved noise performance below 1 MHz (i.e. for some MF, LF and below)
- Improved dynamic range below 2 MHz both in tuner mode and HDR mode
- HDR mode below 2 MHz giving overall dynamic range and selectivity advantages
- Software selectable choice of 3 antenna ports
- External clock input for synchronisation purposes, or connection to GPS reference clock for extra frequency accuracy
- Excellent dynamic range for challenging reception conditions
- Free use of Windows-based SDRuno software (check website for versions supported)
- Free use of SDRconnect SDR and server software for Windows, MacOS and Linux (Check website for versions supported)
