Portable Tinysa Spectrum Analyzer, AURSINC V0.3.1 Handheld Frequency Analyzer, Signal Generator 100kHz to 960MHz MF/HF/VHF UHF Input ESD Protected Function with 2.8 inch Touchscreen

The TinySA Spectrum Analyzer is a remarkable tool packed with features in a compact, portable design. Despite its small size, it delivers accurate and reliable results, making it perfect for hobbyists and professionals alike. The interface is intuitive, with a clear display that’s easy to navigate, even for beginners. I’ve used it to analyze signals across a wide range of frequencies, and it performs exceptionally well, providing detailed insights that are usually found in much more expensive equipment. The rechargeable battery and portability are huge pluses, allowing me to take it anywhere. If you’re looking for a powerful, budget-friendly spectrum analyzer, the TinySA is an excellent choice. Highly recommended!

This is thesecond one of these units I purchased. It is a must have device for any theatre sou t engineer. I keep one in my backpack and one in my gear bag so one is always available.

I use this almost everyday working with rf mic systems. After a couple of months working with it I really like it as a way to see the rf space in the environments I work in. It’s not my only tool in my work but it helps me to plan out what frequencies I can use and what bands I can operate on. In that regard, It’s been a good tool. It’s held up well but im quite protective of my gear so im not throwing it around. But it seems reliable and a nice addition to my bag.

I am used to Spectrum Analyzers being big and not very portable. This one will fit in a shirt pocket. So going in the atticor on they roof, easily fits in pocket to keep your hands free. Also uses a rechargeable battery and uses USB C charging. For OTA Antenna alignment, if you know the frequency of the stations or group of stations you are trying to receive, just connect the rf cable, set your frequency range and rotate your antenna while monitoring signal levels on the TinySA. I bought specifcally for that purpose, but it also operates as a signal generator. Haven't used that function or had the need too. There is not much more I can say that others haven't already said. Decent product at a fair price.

I've used HP SAs and to tell the truth this one won't meet Aerospace standards. But considering that most ham and consumer applications don't need that degree of compliance, imo, this device exceeds expectations. It has most of the features I expect from an SA. I trotted it through almost all of it's settings except for measuring phase noise. The accuracy of the device depends on how you set up the display and RBW. At first when measuring the frequency of the output of my handheld at 146.49 MHz the marker was way off but by adjusting the RBW and sweep settings it was spot on. Oh, btw, you'll run into the same issues when using a high end SA. The only limitation I see with the device is the upper limit of 900 MHz. But that can be worked around with an external mixer and the appropriate LO. We did that at the last place I worked at with an older noise figure meter that wouldn't work into the x-band. Since I don't intend to work above 70cm it isn't a problem for me. The only thing I need is a directional coupler for 3rd order measurements. I was disappointed with the PC interface software but I think that may be because it wasn't written for Win10. The documentation for the device will not teach one how to use an SA. It is not an O'Scope and the settings are not intuitive. This is a sophisticated piece of test equipment that requires training to use. I would recommend going to the HP or Agilent web sites to learn how to use their equipment which will port over nicely to this piece of gear (or find an Elmer).

This thing is a little dynamo. The box says tiny, and they’re right about that - it’s small enough to just barely equalize on the table with the included antenna deployed. I’m planning on mounting this in my ham station. It’s accurate, sensitive, and information rich. I can’t believe this little champ was so cheap.

Utilization is daunting at first, through the website instructions and YouTube, I am able to explore a lot now, and know what I am looking at, I am not a professional in any means, so this was completely new to me, I utilize it now through my work on radios, primarily testing the range sweep for finding out if the radios are in tune our have drifted out of tune. I am still working on learning all the features, but it is a great tool. The readability is good, small screen, but you can hook it up to a computer for a broad view, battery life, so far, no issues with what I am using it for.

This radio would be 5 stars but for one very bad flaw. While 70c and 1.25 meters are clean the 2 meters band has very bad transmission on adjacent frequencies. So if you use 2 meters you will be transmitting and interfering with other frequencies out side the ham bands.

Definitely small! Works as intended.
