SDRplay RSPdx 1kHz - 2000 MHz Wideband SDR Receiver

Supplied by SDR-Kits - Authorised Distributor of SDRplay Radios since 2015 

A replacement for the highly successful RSP2 and RSP2pro models, this mid-range SDR Receiver has been extensively redesigned to provide enhanced performance including additional and improved pre-selection filters, improved intermodulation performance, the addition of a user selectable DAB notch filter and more software selectable attenuation steps.

With three software selectable antenna inputs and free professional software providing an ever-increasing feature set, the versatile RSPdx is also ideally suited to a wide range of industrial, scientific & educational applications.

Used in conjunction with SDRplay’s own SDRuno software, the RSPdx features a special HDR (High Dynamic Range) mode for reception within selected bands below 2 MHz, delivering improved intermodulation performance and fewer spurious responses for these challenging bands.

The RSPdx also features a 24 MHz ‘plug and play’ reference clock input which allows the unit to be synchronised to an external reference clock, such as Leo Bodnar's GPS disciplined oscillator (GPSDO).

The Receiver comes fully assembled and tested, and requires a Personal Computer, one of the SDR Receiver Application programs as well as a suitable antenna to provide excellent communications receiver functionality.

 Key Features

  • 14-bit SDR Receiver covering 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 10 MHz of spectrum at a time

  • Supports up to 3 simultaneously connected antennas (2 x 50 Ohms and 1 BNC Connector for lower frequencies)

  • External clock input and output for synchronisation purposes, or connection to GPS reference clock for extra frequency accuracy

  • Performance below 2MHz substantially enhanced - improved dynamic range and selectivity

  • Enhanced ability to cope with extremely strong signals

  • Excellent dynamic range for challenging reception conditions

  • Housed in strong steel case

  • Multiplatform driver and API support including Windows, Linux, Mac, Android and Raspberry Pi 3/4

When used together with SDRplay’s own SDRuno SDR Software, the RSPdx becomes a high performance general coverage receiver or spectrum monitoring instrument for the lab. A stand alone spectrum analyser software package is also available.

Package Contents: 1 pcs SDRplay RSPdx with "Getting Started" information.

Note: The SDRplay RSPdx requires a standard USB-A plug to USB-B plug Cable. This USB Cable is NOT supplied with the RSPdx as the majority of buyers will already have such a cable available.

SDR-Kits Warranty includes parts and labour and the cost of return shipping, provided the product has not been misused. Specifically the RF Power applied to the RSPdx Antenna sockets should be limited to a maximum of +10dBm to avoid damage to the RSPdx.
