Seesii 4.0インチ TinySA ウルトラスペクトラムアナライザー

【1】

I am very pleased wit this unit. I have checked out it's performance with my other lab equipment and it performs very well given it's price. Will be very useful for field testing because it's battery-powered. I took some pics of the inside. The quality of construction is very good. It's very clean inside not even grimy fingerprints are to be found. I only had to get an inexpensive RF source to calibrate above 5420 MHz, which can be found on Amazon ($60).My advice regarding the TinySA Ultra - Get one!

I bought this to keep in my laptop bag for quick frequency scans at broadcast sites. I am surprised it works so well! In one instance, I used it to investigate interference to the LTE cellular band (720MHz), and was able to not only identify the source, but also confirm corrective actions were successful. I upgraded the software to allow for use past 1GHz and was able to clearly view an L-band signal out of a satellite LNB (~1100MHz).The screen is small and navigating the menus is a little awkward at times using the included pencil, but it's fine in most cases. And remember this is not a $15k analyzer, so the VBW, RBW and sweep times are not going to compete with one that is priced 1000x more. But for something that is small enough to fit in your hand, runs on batteries (for quite a while, honestly), and does a good enough job for most simple tasks, you can't beat it.Don't forget to buy a few SMA adapters, too.

It does what other expensive equipment does at a fraction of the cost.

I love this device. Sole people say they are too small. But they must have gotten the smaller version. It does more than I know how to do. I use mostly to test antenna SWR and it works great for that. I wish I knew more about the other functions as I know it can do a ton of stuff.It’s great to run a wide sweep of an antenna.It actually helped me finally determine a mobile antenna was bad. Not that mount as I previously thought.
