Perfect for the budget shop. Great device for field use as well as the bench.

If you don't work with RF then you don't need it.
Small size, great documentation. Connects to my PC which is better than using eyeglasses. As I've just begun to use it I can't say much more. Very useful to aim satellite dishes at satellites. Depending on the application you need to know the azimuth and elevation of the satellite then use this to find and tune the signal,

Larger Size and Ultra Features Worth the Upgrade.
I had an older 2.8 inch non-ultra version I used a lot to check for harmonics and mixing products. The upgrade to the Ultra version withthe larger screen is sonething I should have done last year! So many new features and the larger display really helps see some of the smaller signals.

Very helpful tool
Very impressive tool, I plan to use it to help manage wireless microphones at small shows and at churches. Went through the video instructions, was super-easy to set-up and understand.

Worth the price and worth getting one.
Been wanting one of these for years and now I can finally afford one. I already used it 2x to track down the RFI I have been getting into my HF receiver. It worked perfectly and found the RFI very quickly. Also, checked one of my HT's to see how clean it was and the harmonics were within specs of the FCC. Good to know that I'm using a good HT on the air. I'm sure I will find many other applications for this TinySA, but I feel it already paid for it self. Only time will tell if this device holds up, but overall a great buy on an amazing pocket size and portable device.

Buy this now!
Be sure to run the self test when you get one, and calibrate it, and you will get great results. I've tested a number of HTs with it already. Love the ultra more than the regular one (I have both).

Good value
This spectrum analyzer is very sensitive and has a max input of five volts. It takes a lot of exploration to figure out how it works. There is little information in the user’s manual so it is necessary to go to the internet for help. There is no one you can call for help.
