Seesii is an authorized seller of the Tinysa and that is why I purchased it from Seesii. Go to Tiinysa and check out their info on this before purchasing. The Tinysa ultra is very practical and fun to use for those who are a bit tech savy. I use it to check the frequency of key fobs for cloning , and cable lines coming into apartments and TV antenna signals. Be careful as the input circuitry is delicate and precautions such as attenuators and a DC block are essential so as not to fry your Tinysa if you are checking your ISP's or external antenna signals. This thing is packed with features. Spectrum analyzers used to cost tens of thousands of dollars. They were big and heavy. This is amazing to have a hand held spectrum analyzer you can carry to locations at an affordable price. The ultra with a 4 inch screen is plenty sufficient. The 7.3 ghz is good for future prospects. Seesii support, if you need it, may not get back to your for a couple of days, but they will get back to you and they are extremely good. Highly recommend the Seesii 7.3 ghz spectrum analyzer, as it comes from a first hand seller and they have support if you need it. Review: Incredible device! - I love this device. The built-in self calibration and the big screen make this my favorite new instrument.

The built-in self calibration and the big screen make this my favorite new instrument. I also love that you can save all settings as template, so easy to jump back and all markers and trace configurations are ready to make a measurement. ### ⭐⭐⭐⭐⭐ New and improved. Sweet! *by M***. on April 19, 2025* The ZS-407 is an impressive upgrade and improvement over the previous model (which I owned 2 of). Although advertised to cover the 100kHz-7.3GHz RF spectrum range, I had no problem observing what I believe to be StarLink Space-to-Earth (Downlink) transmissions with the 10.7-12.7 GHz range (see accompanying photo of a portion of this range, a peak hold spectrograph which I ran for a while until it was completely filled out). The noise levels have noticeably been reduced. The battery life seems significantly improved, even with the display brightness set to the default 70%. The touch screen seems more responsive. It seems to work just as well without the tiny antenna attached as it does when attached. I won't elaborate on the all improvements, as the online wiki manual covers it all. Read the manual to learn of them all. While I have some practical use for this device, I'm finding it fun to play with as much as a video game. Instead of hunting enemy solders on a battle field, I'm hunting for their radio transmissions within the RF spectrum, LOL. ## Frequently Bought Together - SeeSii TinySA Ultra+ ZS407 7.3GHz Spectrum Analyzer: 2025 Upgraded 4 Inch HW V0.5.4 100kHz-7.3GHz Handheld Tiny Frequency Analyzer - 2-in-1 RF Signal Generator 100kHz to 900MHz MF/HF/VHF UHF - SMA Connectors kit 18 Type SMA RP-SMA Adapter Plug and Jack Straight and 90Β° SMA Connector Goldplated Brass RF Coax Connectivity Set for FPV Antennas Radio Baofeng Yaesu IP Camera Project - YOTENKO SMA Adapter Kit 16-Piece, Standard SMA to BNC/UHF/F/N Type Connectors Kit, Antenna Coax Connector Converter Male/Female for WiFi Antenna/FPV Drone/Extension Cable --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/708317625-seesii-tinysa-ultra-zs407-7-3ghz-spectrum-analyzer-2026-upgraded](https://www.desertcart.tn/products/708317625-seesii-tinysa-ultra-zs407-7-3ghz-spectrum-analyzer-2026-upgraded) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-31*
