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. Review: Nice for the price/ But there are minor flaws - 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. ## Features - Frequency Range :Tiny Spectrum Analyzer with two inputs, high quality MF/HF/VHF input for 0.1MHZ-350MHz, lesser quality UHF input for 240MHz-960MHz. Switchable resolution bandpass filters for both ranges between 2.6kHz and 640kHz. Color display showing 290 scan points covering up to the full low or high frequency rangefrequency range. The Spectrum Analyzer contains all the components of a conventional heterodyne swept spectrum analyzer - Built-in Calibration Signal Generator: When not used as Spectrum Analyzer it can be used as Signal Generator, MF/HF/VHF sinus output between 0.1MHZ-350MHz, UHF square wave output between 240MHz-960MHz. Built-in calibration signal generator that is used for automatic self test and low input calibration - Tiny Spectrum analyzers: Switchable resolution bandpass filters for both ranges between 2.6kHz and 640kHz.Color display showing 290 scan points covering up to the full low or high frequency range. Bulit-in rechargeable battery allowing a minimum of at least 2 hours portable use - PC Control: Connected to a PC via USB it becomes a PC controlled Spectrum Analyzer.The USB interface implements the Serial over USB (CDC) protocol and there is a large set of commands that can be invoked over the serial interface. These command can be used to perform measurements or update internal settings. The driver for Windows will install automatically after connecting to a Windows PC. The driver for Linux is built into the kernel - Package List: 1x Tiny Spectrum Analyzer; 2 x 20cm RF Cable;1 x USB Cable;1 x SMA Female to Female Connector;1x Touchscreen Pen;2x SMA Male to UHF Female Cables; 1 x SMA Telescopic Antenna.It's very useful as an antenna analyzer for your ham station, easy to set without fancy calibration ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08YJDZ3SC | | Batteries | 1 A batteries required.

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 ## Frequently Bought Together - Portable TinySA Spectrum Analyzer, SEESII Upgraded V0.3.1 Tiny Frequency Analyzer with Antenna SMA Male to UHF Female Cables, 100kHz to 960MHz MF/HF/VHF UHF Input, 2.8'' Touchscreen Signal Generator - BECEN 10W SMA Attenuator,40db,DC to 3GHz,50 Ohm - DHT Electronics Handheld Antenna Cable SMA male to UHF SO-239 Female Connectors 6'' Pack of 2 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/295539082-portable-tinysa-spectrum-analyzer-seesii-upgraded-v0-3-1-tiny](https://www.desertcart.tn/products/295539082-portable-tinysa-spectrum-analyzer-seesii-upgraded-v0-3-1-tiny) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-08*
