The EMP noise source could be inside the cage/pouch and the analyzer with probe on the outside. Or, the analyzer and probe is inside the cage while the EMP noise is outside. Second scenario would be tricky to trigger and capture unless you use the waterfall. **Q: is there a linux-based version of the app?** A: Yes,it support **Q: can this be used to display and analyze noise on an AC power line?** A: You might be better off with an oscilloscope. The TinySA does not have high input impedance and a direct measurement on the power line would likely damage it (and be very unsafe). **Q: Is this suitable for testing tv vhf and uhf signal strength?** A: Not an expert on TV VHF and UHF, but I believe the TinySA range covers the UHF and VHF spectrum. With some calibration and manual setting (research on YouTube) it will provide accuracy that meets most needs. It is not a $2500 SA, so expect a certain amount of "ok, but its only $50 bucks". Also, ATTENUATE if signal strength/input is expected to be high. Again, research videos with professional testing from engineers. There's plenty of help online. ## Customer Reviews ### ⭐⭐⭐ Es portátil pero requiere una cantidad de señal bastante elevada de cuando menos -40dBm *by on Reviewed in Mexico 17 September 2024* El rango dinámico es bastante escaso por lo que algunas pruebas no las puede hacer. ### ⭐⭐⭐⭐⭐ Small, cheap, very useful tool *by on Reviewed in the United States 15 April 2026* Fun little analyzer. Does all of the basics including measurement functions. Waterfall display has two different size modes which isn’t really indicated on the menu. Signal generator has a wide output level range. AM and FM modulation works well but I haven’t tried external yet. Measurement sensitivity is a little quirky. Amazing capabilities for something so inexpensive. Complements the NanoVNA well. ### ⭐⭐⭐⭐⭐ Great for hunting for stray interference for wireless mic channels *by on Reviewed in the United States 10 June 2023* 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. ## Frequently Bought Together - Portable TinySA Spectrum Analyzer,SEESII Upgraded V0.3.1 Handheld Tiny Frequency Analyzer 100kHz to 960MHz MF/HF/VHF UHF Input,Signal Generator with 2.8 inch Touch Screen with ESD Protect Function - 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 for Amplifier --- ## 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.be/products/445878113-portable-tinysa-spectrum-analyzer-seesii-handheld-tiny-frequency-analyzer-100khz](https://www.desertcart.be/products/445878113-portable-tinysa-spectrum-analyzer-seesii-handheld-tiny-frequency-analyzer-100khz) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-07-23*
