tinySA Spectrum Analyzer review (Banggood)

what is the manufacturer and model number for the generator you are using? Great video, thanks.

Can this be used as R.F. reader to know what frequency has less traffic and suitable to be used for wireless transmission.

Has anyone tried to tune a duplexer with one of these? Looks much easier to carry than my old HP 😂

Be real good if it could cover wi-fi freqs, 2.4 and 5.2 ghz.

👍👍👍

Where can I get printable manual?

Great intro overview. The guitar pick is for touching the screen: you don’t need a pen. The high frequency range covers the 432 MHz band, which is a US UHF band. I guess your country doesn’t use this band.

First things first. BE CAREFUL when using the internal generator of the tinySA, it is somehow buggy and it is really easy to fry your DUT. Switching the AM on overrides yout output level setting, which is a kind of unfortunate, but much worse is that there is absolute no warning, you just set the output level to something low, then turn on AM and bang, you have FULL POWER on the output. Even if you have AM turned on, you can set the output level, but theese settings goes to nowhere until you turn the AM off. This is due to the fact they are using the output attenuator to generate an AM resulting in step-like envelope of the output AM signal and some other issues, which are at least not destructive.

The analyzator itself isn't that bad at all, it has it's limitations, but in my opinion, it is a really amazing device for its price. The biggest limitation is relatively wide minimal RBW, which makes observing audio AM or FM modulation near impossible, so you cannot set the FM deviation using bessel zeros, you cannot observe the AM modulator harmonic distortion and things like that. Also aligning the MF filters of typical AM MW radio using this small SA is at least not comfortable, etc, but I think this small device is ideal to get familiar with spectrum analyzers without risking the expensive equiptment. Theese things are not intended to be a proper test gear, they are just decent toys intended to self education. Just buy one of them, they are no expensive, and play with it for a while. Build some poor man's active probe, some near field probes, noise generator to characterise filters using this tiny SA, whatever. You will learn a lot in a small amount of time and this is what theese things are intended to.

And. That device has a touch screen. If you want to change the RBW? Just touch it! Input attenuation, sweep time or reference level? Just touch it. Almost everything on the display is touchable and UI of that device is very intuitive.

Thank you.

Спасибо за интересный ролик

The tinysa has a built in signal generator would this help me tune a 50 watt duplexer????

Thanks for the video, I might have to buy one of these. Now you have had it a while are you still happy with it please?

It seems to be similar to the NanoVNA but is very different and has more options than the NanoVNA. But the NanoVNA is more common.

Very helpful thank you.

Thank you for the great review. I just got mine yesterday and have not tried it yet so this video was very helpful...

Nice video, Paul. Have you had a chance to hook it up to a transceiver yet to look at how clean the output is? Do you need a set of attenuators to do this safely? 73, M0YZT

I’m interested to buy it to measure FM deviation on CB radio with zero bessel method.
Have you tested this ?

Hi. It seems like LO phase noise integrated is high and also looks like dynamic range is also a bit low isn’t it? Did you checked it?

Thank you for the review Paul!
I had both a Tiny SA and Nano VNA on my 'wishlist' but last Friday my only radio died so I guess I don't have to think that hard about it at the moment... 🤔😞

hello,good video.your blue RF generator is a good device to inject signal in a transceiver to calibrate SWR signal?
thank you

Nice looking kit! Maybe the "pick" is for opening the case? (First). :)
