ALIESTFDNO Upgraded TinySA Ultra Spectrum Analyzer, 4.0 Inch 100kHz to 5.3GHz Handheld Frequency Analyzer with 32Gb Card, 2-in-1 Signal Generator 100kHz to 800MHz MF/HF/VHF UHF Input,V0.4.5.1

A great value for a great tool!

This is a great little version of the well known tinysa and covers a broad range of freqs and should be a great tool to add to my amateur radio toolbox. Updating the firmware is a bit finicky but honestly I can’t say for sure that’s not due to my own computer issues so I won’t ding it for that. On the whole it’s a good SA and I’d highly recommend it.

Nicely made and comes with fairly complete instructions. I am using it for a variety of situations and, so far, it is working perfectly. The size it big enuogh to really get a nice view of the waveforms, but yet small enought to throw in a travel case. Overall, I am very happy with it.

My father is a ham radio operator so I brought this over to his house to compare it to his other equipment. As other reviewers have noted, updating the firmware is a PIT*. He said is compared fairly well with his other equipment but he's not ready to switch that out for this. (Old habits die hard, as the saying goes.) So minus one star for firmware update hassles.

I'm a ham radio operator so I use these all the time and this new version really opens up the possibilities for me. the expanded range covers so much more of the ham bands. the case is much more durable and it no longer activates the touch screen if you grip it to hard.

works great for measuring high frequencies and RF. Seems to be pretty accurate (see picture). Looks like a legitimate TinySA but no way to confirm. One problem is that it did come with a crooked screen. It sounds like this is a common problem with these tinySAs. Otherwise no complaints.

This SA works well and has a broad frequency range. My only complaint is the difficult updating process. It uses a USB-C connector for charging.

The TinySA instructions direct you to update the firmware as one way to verify the authenticity of your unit. Mine will not update. The authentic software indicates my unit will not go into DFU mode even after adjusting the proper Windows setting. Avoid.
