The SDRplay RSPdx-R2 is an enhanced version of the popular RSPdx and is a wideband full-featured 14-bit SDR which covers the entire RF spectrum from 1kHz to 2GHz. Combined with the power of readily available SDR receiver software (including ‘SDRuno’ for Windows and Multi-Platform ‘SDRconnect’ supplied by SDRplay) you can monitor up to 10MHz spectrum at a time.
The RSPdx provides three software selectable antenna inputs, and an external clock input. All it needs is a computer and an antenna to provide excellent communications receiver functionality. A documented API allows developers to create new demodulators or applications around the platform.
Key Benefits & Features:
- Covers all frequencies from 1kHz through VLF, LF, MW, HF, VHF, UHF and L-band to 2GHz, with no gaps
- Receive, monitor and record up to 10MHz of spectrum at a time
- Significantly improved noise performance below 1MHz (i.e. for some MF, LF and below)
- Improved dynamic range below 2MHz both in tuner mode and HDR mode
- HDR mode below 2MHz 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)
- Multiplatform driver and API support including Windows, Linux, Mac, and Raspberry Pi 4/5
- Strong and growing software support network
- Calibrated S meter/ RF power and SNR measurement with SDRuno (including datalogging to .CSV file capability)
- Documented API provided to allow demodulator or application development on multiple platforms
