Portable Tinysa Spectrum Analyzer, AURSINC V0.3.1 Handheld Frequency Analyzer, Signal Generator 100kHz to 960MHz MF/HF/VHF UHF Input ESD Protected Function with 2.8 inch Touchscreen

I use this almost everyday working with rf mic systems. After a couple of months working with it I really like it as a way to see the rf space in the environments I work in. It’s not my only tool in my work but it helps me to plan out what frequencies I can use and what bands I can operate on. In that regard, It’s been a good tool. It’s held up well but im quite protective of my gear so im not throwing it around. But it seems reliable and a nice addition to my bag.

Utilization is daunting at first, through the website instructions and YouTube, I am able to explore a lot now, and know what I am looking at, I am not a professional in any means, so this was completely new to me, I utilize it now through my work on radios, primarily testing the range sweep for finding out if the radios are in tune our have drifted out of tune. I am still working on learning all the features, but it is a great tool. The readability is good, small screen, but you can hook it up to a computer for a broad view, battery life, so far, no issues with what I am using it for.

The TinySA Spectrum Analyzer is a remarkable tool packed with features in a compact, portable design. Despite its small size, it delivers accurate and reliable results, making it perfect for hobbyists and professionals alike. The interface is intuitive, with a clear display that’s easy to navigate, even for beginners. I’ve used it to analyze signals across a wide range of frequencies, and it performs exceptionally well, providing detailed insights that are usually found in much more expensive equipment. The rechargeable battery and portability are huge pluses, allowing me to take it anywhere. If you’re looking for a powerful, budget-friendly spectrum analyzer, the TinySA is an excellent choice. Highly recommended!

I am used to Spectrum Analyzers being big and not very portable. This one will fit in a shirt pocket. So going in the atticor on they roof, easily fits in pocket to keep your hands free. Also uses a rechargeable battery and uses USB C charging.For OTA Antenna alignment, if you know the frequency of the stations or group of stations you are trying to receive, just connect the rf cable, set your frequency range and rotate your antenna while monitoring signal levels on the TinySA.I bought specifcally for that purpose, but it also operates as a signal generator. Haven't used that function or had the need too.There is not much more I can say that others haven't already said. Decent product at a fair price.

Who would have thought that you could have Spectrum Analyzer AND Signal Generator capabilities for such a great price? I've used this unit at home and to measure spectrum at a repeater site. It works well standalone, BUT connecting it to a laptop gives you a lot more flexibility, ease of use, and ability to save or record measurements for future sharing. I've also used the Signal Generator function. You can even enter PL or CTCSS tones for FM modulation to test repeater receivers.

Good for what I need it for ....Nice piece of equipment !

easy to use for many applications at great price, worked well for me to count signal frequencies

I saw this unit on Youtube, Shango066 using it to repair radios and TVs and had to have on.You can use it to generate frequencies, such as IF, or to align receivers. And the Spectrum Analyzer can be used to see if the local oscillator is working.It works quite well, having this replaces a lot of large bulky equipment.
