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.

The real McCoy. It’s weightier & has branding in the packaging.

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

I have been using this analyzer to check output on a specific frequency around 27 Mhz. So far it has picked up on it and possibly found a faulty electronic component as well. I would have given it 5 stars, but the white lettering on the case is so faint or lack of ,does not match the picture for this item being for sale. It may have been rubbed or buffed off at some point in time.

The low input shows the VHF channels and the high input shows the UHF channels from my OTA TV antenna input signal.

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.

Spectrum analyzers are not cheap! The Tiny SA is at a very reasonable price for an Amateur Radio enthusiast or general hobbyist. This instrument coupled with the Nano VNA adds a lot of power to the end-user's toolbox.

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