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: If you know you know - Its amazing. And if youre buying it you already know what it is. So I wont go too in depth. I reccomend it. ## Features - 2026 Upgraded TinySA Ultra+ ZS407 Spectrum Analyzer (7.3GHz): delivers lab-grade precision with the latest HW V0.5.4, a 4.0-inch HD touchscreen (480×320, up to 450 scan points) and built-in ESD protection for stable, professional performance in RF development, satellite alignment and frequency verification. - Broad 100kHz–7.3GHz Spectrum Analyzer coverage for 5G NR, Wi-Fi 6E and satellite communications testing — level-calibrated up to 8GHz for high-frequency lab work.
