Hello, and welcome to the RSP Spectrum Analyser website. The analyser is SDR-based  and has been written to support the full range of SDR radios manufactured by SDRplay, including the new RSP1B. and the RSPdx_R2. The analyser is capable of resolution bandwidths of less than 1Hz with sensitivity better than -145dBm. In addition to being able to run five separate traces, the analyser offers the ability to capture screen shots, export data in a range of formats and includes a versatile marker system. The analyser includes a comprehensive user manual and offers a very useful addition to any workbench.

The analyser includes the facility to control an external signal source in conjunction with a Arduino Uno module so that a fully synchronised tracking generator may be realised. For the tracking generator, support is offered for the Analogue Devices AD9850 and AD9851 DDS modules, as well as the Skyworks Solutions SI5351A clock generator module,  all of which are readily available on eBay.

Additional support is offered for the GRA-AFCH AD9910 DDS module which includes accurate output level control with a maximum frequency output of 400MHz, or 600Mhz with overclocking. In addition AM and FM modulation facilities  are provided thus providing a very useful signal generator. Further information can obtained at RF Units - GRA & AFCH

Facilities are also offered to allow the user to communicate with, and control their own custom-built tracking generator using a simple command structure over a serial or USB link. Demonstration source code is available in the Files section of the Facebook Group page.

The analyser has it's own dedicated Facebook page where support is offered, and general discussion can take place between users. You can find the page here: Spectrum Analyser Facebook page Users are encouraged to check this page for the latest news regarding software updates and additional files downloads.

Please note than any link on this site will open in a new tab so you can feel free to view all external links without having to leave the spectrum analyser website.

Finally I would like to offer my most heartfelt thanks to the crew at SDRplay. Without their advice, support and encouragement, this project would never have come to fruition. Thanks chaps, if I ever make it back to the UK, I owe you a pint - or several.

They are a very friendly bunch, offer a fantastic product and place an absolute premium on service and support. Why not visit their website at SDRplay 

Updates to the website will be announced on the Facebook page. If you would prefer not to use Facebook, then check back here periodically for any changes.
