    • Great for hunting for stray interference for wireless mic channels
Style: TinySA
Radio frequency spectrum analyzers can be very expensive, heavy and complex. Only in the last couple of years has the technology been available, at a reasonable performance level and portability. TinySA (and it's big brother, TinySA Ultra) and RF Explorer are the leading breakthrough products in Spectrum Analyzers. They each excel at different aspects of measuring RF and , all in a similar price ballpark. The original TinySA is by far the cheapest, at around $60-70. It is also the most feature-limited (though it is very full-featured by historical measure). It is marketed largely to ham radio operators, but I bought it to sniff out RF interference that might affect my wireless microphone systems that I use for my documentary work. Documentation is a bit sparse, as this is designed and supported essentially by a single person. There is no documentation in the box. However, there is a Wiki and series of short tutorial videos created by the developer to cover setup and menu controls. Most third-party reviews and video tutorials focus on ham radio and other use-cases that are unrelated to my needs. The TinySA's 0-950mhz band width is perfect for me to sniff out the UHF band from 470-608mhz (the remaining legal bands in the US) for interference sources. This device is described as "less accurate" in the 350mhz and up band, but it's plenty accurate enough for me. If I was coordinating large numbers of wireless mics for a venue or a large production, this would not be the best tool for me. I would be much better served by the 3x more expensive RF Explorer, which has a decent desktop computer application and can export frequency scans to a file that can be read by Shure's industry standard free frequency coordination app ( must, if you are looking to coordinate large numbers of RF sources. RF Explorer is a professional standard in portable RF test gear that can interface with the apps for advanced analysis and frequency coordination. TinySA Ultra has a bigger screen and extra bells and whistles and boasts a much broader range of frequencies it can scan (including way up into the wifi range) but if you just need a very portable, reliable, inexpensive standalone RF "sniffer" to help you avoid and solve RF interference problems in frequency ranges up into the UHF range, TinySA does the job beautifully. ... show more

    • Nice for the price/ But there are minor flaws
Style: With Antenna Cable
The TinySA works just fine! And so far in testing, the accuracy of this device is not to bad. First thing, an ACTUAL instruction manual would have been really nice. There is no documentation at all on how to operate the TinySA. Luckily there are several YouTube vids out there to help you along.. The menu IS a bit confusing.... There is a lot of back and fourth in the menu to set the parameters you desire. Once again, nothing is clearly explained. The “LISTEN” feature seems to be disabled, this allows you to listen in on the frequency being monitored. I don’t even think there is an actual speaker in this unit. This is my MAJOR DISAPPOINTMENT! As this feature would have been very handy from time to time. When doing the SELF TEST of CALIBRATION, the high and low ports must be connected together with the supplied jumper cable!!! If you do not follow this procedure, the unit will fail the test and not calibrate correctly. For the price, it’s definitely a great unit and worth every penny....... Just watch the videos on how to use and setup the TinySA, as I stated..... It is a bit confusing to operate. ... show more

    • Decent Product, Has Some Quirks
Style: TinySA
This is overall a pretty decent spectrum analyzer for the price. Good for hobbyists, but I would not say it's good for much else. It's small and portable. I can't fully vouch for the accuracy of it, but the few items I've tested with known frequencies, it picks up fairly well. The only negative feedback I have for this product is that the touch UI is super finicky and the screen calibration seems to be off. But other than that, like I said, good for hobbyists ... show more

    • Great little instrument
Style: TinySA
It obviously has some limitations, especially resolution bandwidth, image rejection and scan speed but for the price and size it is extremely useful. With careful use, some external attenuators and filters it is capable of quite good accuracy and performs 90% of the tasks you want an SA to achieve. There is no tracking generator but a noise diode is an easy to build replacement for many uses - however you may as well just buy a NanoVNA too which has a reflection bridge built in. Heck with some software you can even use an NanoVNA as a tracking generator for the TinySA but it isn't a very pure source and would need filtering. The antenna that comes with it is very fragile. I broke it quickly. The connection between the telescoping bit and the SMA connector is implemented in a very thin-walled metal tube just after the hinge joint where it passes through the white insulation. It snapped at this point without a lot of pressure while attempting to move the hinge joint which was fairly tight when I received it. I'd recommend slackening the screw in the hinge a little to minimise the force needed and reduce the risk of breaking the thin connection to the SMA center pin. ... show more

    • A very valuable tool and a lot of fun.
Style: TinySA
If you've never owned a spectrum analyzer, the TinySA is magic! It comes with a small telescopic antenna and a charged internal battery so out of the box you can immediately see RF from AM to UHF in a way that is far more convenient than using an SDR. It's also a lot of fun to wander around and visualize RF wherever you are. Its measurements are not as detailed as an SDR but they work really well together: see something on the TinySA and then tune in to it on the SDR. When the SDR suffers from desens, the TinySA immediately shows you where it's coming from. With the built-in battery it's useful for hunting RFI, although the screen is not bright enough to view in full sunlight. All in all a very useful tool. ... show more

    • Buy it from somewhere else
Style: TinySA
The product is good. It works as intended. The issue is Amazon! The shipping is so slow you are farther ahead to get it elsewhere. The customer service is so bad that it took 4 phone calls to get the item shipped. Great product if you use Ali-express or temu, or even ebay!
