Spectrum Analyzer, 2023 Upgraded TinySA Ultra Spectrum Analyzer with 4.0 Inch Sensitive Touch Screen, Handheld Tiny Frequency Analyzer ith 32Gb Card, 2-in-1 Signal Generator

I cannot believe this thing, it truly is awesome, all that it does, for the price and size!!! Used to be, if you wanted a S.A., you had to be RICH, and not worry about eating every day !!!! But, even, I, can afford this one!! And I love the fact that you can HEAR the "spike" you are monitoring to find out who, is causing the interfering harmonic(s). And, it is not like the older ones, as big as the pickup truck you needed to haul it around, and it actually fits in your pocket, with room to spare! (Maybe I should get one for every room in my house!:)

Very useful if you are into radio stuff. Great tool for ham radio operators. Easy to use. Highly recommend.

learning curve

I used it to check harmonics on my cheap HT's, as expected they were all pretty bad. But also fun to scan the spectrum to see what frequency things are on. My truck key fob shows up in the 400mhz range.

First of all this unit is pretty small, very light weight. comes with a few connectors to do self calibration, a small antenna, usb cable to charge unit, a 32gb microsd card, an earphone listen jack, a strap and stylus . Basically it's operation out of the box, which is pretty cool. You can use it to see what RF is being emitted around you, if it's an radio signal, you can hear the station with headphones. But this is mainly used to test radios and other items that emit radio waves. With ultra mode, you can set from 0-5.3ghz which is pretty wide. The screen is pretty dinky but it's easy to read and clear. Overall for the price, a pretty powerful frequency scanner. Only thing i worry about is longevity of the battery from constant charging. It might be easy to fix is if the built in battery dies, probably can find a replacement rechargeable battery and solder it back in.

I'm a sucker for gadgets like this. Obviously it's not a $3,000 SIGLENT, but for the price it does a good job.

For $65 it’s enough to get you started, learning and then some.2 thumbs ups

I could not afford a IFR analyzer on my bench so I grabbed this when I saw it. Great buy for the money. Curious how it will work on microwave freqs. But so far on hf vhf and uhf seems right on!
