SATSAGEN Spectrum Analyzer Software Updated: Now Supports RTL-SDR
Back in March last year we first posted about the release of SATSAGEN, and program by Alberto (IU1KVL) that allowed the PlutoSDR to work as a spectrum analyzer. SATSAGEN has recently been updated to version 0.5, and it now supports the RTL-SDR, HackRF and Simple Spectrum Analyzer hardware as well.
Spectrum analyzer software allows you to monitor spectrum activity over a bandwidth much larger than what your SDR supports. It works by rapidly sweeping over multiple frequencies and stitching the spectrum slices together.
Some highlights of the new features include:
- Works with:
- ADALM-PLUTO
- HackRF One
- RTL-SDR Dongles
- Simple Spectrum Analyzer series like NWT4000, D6 JTGP-1033, Simple Spectrum Analyzer, and so on.
- Video trigger, real-time trigger, and fast-cycle feature
- ADALM-PLUTO custom gain table and Extended linearization table for all devices
- Transmit from raw format files
- I/Q balance panel
- Waterfall

Hello Alberto,
great work and improvement for getting affordable DIY test equipment
“Dreaming Mode” on
since you support already Full Duplex TRx SDR, do you think implementing a tracking generator like old YIG based SA used to have is feasible, since todays SA don’t have it any more?

Hi!
I don’t know if I understood your dream. SATSAGEN can be used as a tracking generator to drive an external scalar analyzer with this simple HW interface https://www.albfer.com/usbdaramp/#content
Let me know if it’s suitable for your needs.

SATSAGEN also includes the SA with a tracking generator stand-alone with the TSA feature.
Will the SDRPlay be supported?
Hi Lasse,
I would like to support it, but I would need the hardware to make the linearization data, tests.

Hi Alberto.
Downloaded version for Windows. Unfortunately it does not ask for install location, only installs to C:\Program Files …… I’d prefer to install it on a different drive with rest of my SDR software.
Can this be fixed in the next version?
Hi Rick!
Yes, I’ll try to insert the path destination dialog in the next release.
Thank you

It’s great software! I love it using with PlutoSDR but it has failed to locate RTL-SDR. I will check it again for RTL-SDR. It shall be great if the support is extended to USRP as well.
Hi Mir,
Thank you! Let me know about your problem with RTL dongles. We could find a fix.
I want to extend the support to USRP, but I need the hardware to test all.
Regards
Alberto
This is great news! Though I’m now wondering whether anyone has a recommendation for SpecAn s/w that works with the LimeSDR as well?
Hi Linden,
It will be SATSAGEN, maybe. I started developing the LimeSDR support, but I need to buy that hardware to continue.

Awesome stuff! Looking forward to it!
Amazing software that makes a very useful tool out of PlutoSDR.
I’ve used the Spectrum Analyzer to compare a few antennas, and Generator to check capabilities of my oscilloscope, both features works flawlessly and are very easy to use.
Works great with PlutoSDR, but I couldn’t make it work with HackRF (it just shows an empty modal dialog for a short time and then crashes). Maybe there is something wrong with my HackRF, or drivers, but it works with SDR#
Thank you so much, Val!
I’m working on the next release of SATSAGEN to fix the support of the HackRF with old firmware; maybe it solves your problem.
Regards
Alberto
