Default New 14-bit SDR from SDRplay - the RSP1A

SDRplay Limited has today announced the launch of a new Software Defined Radio product – the RSP1A.

The SDR-play RSP1A is a major upgrade to the popular RSP1 and is a powerful wideband full featured 14-bit SDR which covers the RF spectrum from 1kHz to 2GHz.

Due to its exceptional combination of performance and price, the RSP1 has proved to be a very popular choice as an “entry level” SDR receiver. Since launching the RSP1, we have learned a great deal about what people are looking for in SDR receivers, and where possible, we have incorporated these improvements and new features into the RSP1A.

The RSP1A therefore delivers a significant number of additional features which result in benefits to amateur radio enthusiasts as well as significant benefits for the scientific, educational and industrial SDR community.

Here are the main additional features of the RSP1A compared to the original RSP1:

ADC resolution increased to 14-bit native for sample rates below 6MHz, increasing to 16 bits with decimation.
Enhanced RF pre-selection (greater filter selectivity plus 4 additional sub-bands compared to the original RSP1) for reduced levels of spurious responses
Improved LNA architecture with variable gain. The RSP1 had just a single gain step.
Improved intermodulation performance
Performance extended to cover 1kHz to 2GHz with a single antenna port.
Bias-T facility
Improved frequency stability incorporating a 0.5ppm TCXO (software trimmable to 0.01ppm)
Selectable broadcast AM/FM/DAB notch filters
RF shielding within the robust plastic casing
When used together SDRplay’s own SDRuno software, the RSP1A becomes a high performance SDR platform. The benefits of using the RSP1A with SDRuno include:

Highly integrated native support for the RSP1A
Calibrated RF Power Meter with more than 100dB of usable range
Calibrated S-Meter including support for IARU S-Meter Standard
The ability to save power (dBm) and SNR (dB) measurements over time, to a CSV file for future analysis
The IQ output wav files can be accessed for 3rd party applications
SDRplay has also worked with developers of the popular HDSDR, SDR-Console and Cubic SDR software packages to ensure compatibility. As with the RSP1, SDRplay provides multiplatform driver and API support which includes Windows, Linux, Mac, Android and Raspberry Pi 3. There is even a downloadable SD card image available for Raspberry Pi3 which includes Cubic SDR.

The RSP1A is expected to retail at approximately 76 (excluding taxes) or $100 (excluding taxes)

Default rsp 2 upgrade?

Will the RSP 2 receive any of the upgrades now on the new RSP1A?

Do you mean a replacement for the RSP2 with a RSP2A or... ?

Some of what was added to the RSP1A is already part of the RSP2. Like the T-Bias. Other items are at the hardware chip level.
