I'm looking at getting a spectrum analyzer to investigate the spectral purity of my over the air signals.
I was looking at the Tiny SA (and its clones). Does anyone have any experience with this piece of equipment?
I do! That is the one I use as you saw in the pictures I showed with the bad Wholehouse 3 reading as compared to the Decade, Retekess etc....It is a great one that is affordable and takes the signal over the air. Small....2 1/2" by 3 1/2" so not a large display like the bench top ones but can view everything just the same with what we are concerned with without spending hundreds and even 1000s for one.
You will have to see how to navigate through the menu and the settings. Measures harmonics/spurious stuff, can change resolution to zero in on your frequency, check your frequency accuracy, start stop at any frequency range you want, you can see your audio vs carrier and if you are overmodulating into adjacent frequencies of a commercial station as you see all the commercial stations also. You can zero in on the aircraft band and make sure you are not getting into that 110 - 160 mHz. Shows AM also.
Make sure you get the genuine one if this is your one of choice. The one on Amazon is the real one but I think you tube has a few videos on how to tell a clone from the genuine one.
The genuine is designed by Erik in the Netherlands on the back label.
Amazon has the real one and clones. The clone is $89.99 or less and the genuine is $109.99 currently on Amazon Canada.
The genuine one has the text on the upper right side
"SeeSii" and on back label says designed by Erik in the Netherlands.
I find the Tiny SA to be amusing and generally good for "this looks like something is up, better get the real SA out and investigate". I pull out the Rigol DSA815-TG at a minimum when I want to actually know what's out there. Of course I justify it because I use it at my commercial radio engineering job. Hard to justify the cost for Part 15 only.

I have an RF Explorer handheld spectrum analyzer which can be ordered with different innards for looking at different portions of the spectrum. It also has room to add a second circuit card for further spectrum coverage. The one I have is intended to view the 2.4 GHz Wi-Fi spectrum, and I added a second card to it that shows 23 MHz up to about 3 GHz. I don't know what a professional engineer would think of it, but it contributes to my sense of radio fun.
