TinySA Spectrum Analyser Review & Unboxing and Tests with Oscilloscope | RF Analyser

[@Neptunium]

Very good review! I really like mine ! You know there is a PC software you can download free.. it offer a more comfortable view and it's a great way to share your screen too! Cheers my friend!

@@Neptunium thanks for the tip ! I already had the software, but i sort of forgot about a older screenshots I had to share as example. Also, remember when in your skin walker ranch debunk you also talked about the "mysterious radio signals" and then you revealed that the antenna probably picked up some noise from the monitor ? For whatever reason, my monitor can interfere with walkie talkie at 446,04 MHz or so. I don't exactly know why a monitor can possibly do such high frequencies. I did capture my computers almost 1 GHz clock, but the monitor has no reason to 🤣.

@@photonik-luminescence I think there is some resonators in the screen electronic that generate a specific frequency, if the interferences are evenly spaced out, there is a good chance some sort of component in the screen is generating that . Especially if it gets stronger as your antenna gets closer to the screen ...

Great review, thank you but you can't call this completely gapless coverage across the whole spectrum it is capable of tuning (in points) because 290 scan points is pitifully small for the amount of spectrum it can scan in one sweep. It's usable for many things regardless, but the span width must be set to a narrow portion of the spectrum to work well enough, otherwise you will miss a lot of the carriers which are really there if trying to view the whole 100kHz -960 MHz spectrum this unit can scan with 290 scan points. After all, it's just a scanning receiver with an analog peak response stored digitally and displayed, as it skips from one scan point directly to the next without receiving anything in between each point (outside of its resolution bandwidth, that is). Yes, it's easy to take fault in such an inexpensive device, you get what you pay for but even then, this really is a very low price regardless.

@@laserhobbyist9751 thanks alot for sharing your opinion. In a way, that's the problem with it's low scan resolution combined with the awfully long sweep time while at high scan. When i mean "gapless", i mean there's no magic cut through out the spectrum like a dead spot as in it's continuous. The lower side of the spectrum in kilo Hertz is the less usable part, but generally there seems to be no huge gap. You reffer to it's scan resolution, wich i agree. I bought a USB SDR, and would like to compare it with and see if something changes in the spectrum like seeing more signals all the sudden. For example, i was able to detect harmonics of my walkie talkie only when choosing a fairy narrow window. In conclusion, you are right. But i rather call this disatvantage limited scan resolution. However, considering it's price, it is still a pretty decent device. Hence, i stated it isn't the best spectrum analyser, but absolutely worth the price considering the cost for a real one.

Hello, i am back from doing some more experiments combined with a Walkie talkie that can also do a spectrum. I was able to pick up the ISS with that walkie talkie (Quanshen K5(99)). I can say that after analysing some frequencies, the TinySA is pretty precise in terms of frequency value. I agree with you that when looking at a certain spectrum (like air band, ham bands and etc), it's true that the firsy glimpse, doesn't give you much of a view unless you expect a frequency in a certain interval. So indeed, it's slow scan in analysing a band effectively is kind of a barrier, stopping it from being perfect, but all in all paired with an antenna, the TinySA and still pretty useful. The term "useful" depends on your definition tho, and more so why you would buy it in the first place. At least I was able to use the TinySA to test the claimed 10 MHz on the walkie talkie (wich showed me that the same signal strength was not shown at 10MHz as 20 MHz, but originally the walkie talkie was addressed to only listen at 20 MHz minimum).

Ultimately, it also depends on why you would buy it and what your expectations are. I am able to view most AM carriers, and it could be a cheap scanner monitor (I now have more expensive one, but no visual representation). In the end, i bought my TinySA out of curiosity to analyse the RF world, less so to listen to it (The scanner Albrecht AE355 something is of course more precise and quicker at finding any carrier). Tho this besg the question, what if the Quanshen K5 with egzumer is a better TinySA (because it's cheaper and it's a two way radio), then the actual TinySA.
