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 tinySA 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 & ESD Function: 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.The performance of the 2021 latest version 3.1 will be more stable and sensitive, with a new ESD protrcted function enable the product to have a higher antistatic level and a longer service life - 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;1 x SMA Telescopic Antenna.It's very useful as an antenna analyzer for your ham station, easy to set without fancy calibration.The firmware of the tinySA can be updated by the user.

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. ## 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.tn/products/229492526-portable-tinysa-spectrum-analyzer-seesii-upgraded-v0-3-1-handheld](https://www.desertcart.tn/products/229492526-portable-tinysa-spectrum-analyzer-seesii-upgraded-v0-3-1-handheld) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-17*
