The TinySA A Spectrum Analyzer and Signal Generator. Let's Take A Look!

This Very tiny cool little product fell into my lap right when I needed a way to find the frequency for a pair of radios I was working on. While I am in no way an expert on the use of this tool, I can say that the potential is there!

Very cool, but shouldn't you have the antenna attached (vs the loop-back cable) if you're looking for RF signals?

[HillOrStream]

That you can hook it to a PC for "unlimited" measurement points is interesting.

Alot of the newer 10 meter radios are off frequency slightly or drasticly depending how stable they are setup cold at the factory. Which is the issue with cheaper mass production. They dont warm the radios before alignment. I think everyone should learn how to align radios. I bought a crt 9900 off some one and he had managed to blow 2 finals and totally screwed up the radio alignment. And no signal on the S-meter. He had been in the engineers menu and screwed up all the settings. But i still bought it. 30 minutes plugged into the Marconi 2950 i learned what every setting did and put the radio right again. Infact probably better than factory. And some test equiptment aint that expensive. Like the unit you are using. Its well worth learning how to do it all yourself.

Nice intro to a valuable tool. At first I was confused as I thought the TinySA was the same as the NanoVNA but it is a different instrument. Might be helpful to other’s like me to point out the difference. The two different instruments look the same before you turn them on. Even the packaging looks similar (I got my NanoVNA fro Nooelec).

Hmmm...wonder if this will work for ota television signals?

[poppasmurf]

Are there any electronics these days not Hetcho in China? I'm really trying to not feed the CCP anymore.

[jgstevens]

Thank you Eric. I can see the value in this tool. Appreciate you looking out for us.

[buffdelcampo]

I have to have one of these. Thanks for the video.

[willemjordaan]

Hi, nice video. Just a question, can it be set to generate on one output and receive on tje other one? Sorry also no expert but looking for some thing to help alight duplexers.

[justkelly]

I cannot for the life of me figure out how to use this thing to calibrate a jpole antenna. I cannot find an instruction manual anywhere.

[Dallas-Rife-UDX--Tennessee]

That’s a good reference tool for sure 👍

Damn, the frequency spectrum analyzer I have weighs about 400lbs, never seen such a compact unit, iam going to look into one. Thatl come in handy realigning vacuum tube transceivers. 👍

[johnblanton]

Nice piece of equipment ! It can clear out some space on the work bench. Gotta have one !

[johnnybodangus]

I didn't know they had these with signal generators now, cool!

[RadioTech]

Well hello Eric I wouldn't mind having such a thing like that if it's got a signal generator in it because it beats having $10, 000 Service monitors just to do with this thing can do as far as retuning radio equipment and what not in fact I wouldn't mind having one now because I've got several radios that are starting to drift and I want to be able to fix them but I don't have one of those fancy service monitor things. also I sent you an email last night and I'm hoping to hear a response back if you wouldn't mind.

I don't think SDR has anything to do with waterfalls. Big boi superhet radios like the FTDx-5000 have an optional waterfall addition to go along with it. I think it is just the fact that the waterfalls are coming in the age of SDR. And SDR isn't any better than the high end superhets.

i have one those i bought my back in march 2021 you can make any antenna you want. maybe you build cb radio homemade beam antenna also i wish there video how hame made gamma match goes homemade beam antenna.

[richpaul]

Thanks, and yes, I understand you're not an expert in this equipment. But I was hoping that you demonstrate exactly how to find a specific frequency from a given CB channel, (AM, USB and/or LSB) and then read what the Tiny SA said that channel was as opposed to what the radio said it was. Of course, most CB radios would need to be opened up and then the adjustments would be tuned in based on what the SA said.

However, some 10 meter/CB radios, like my Stryker SR-955HPC has a "Clarifier" dial that allows me to change the frequency with course and/or fine tune abilities. So, I was wondering if that was something that could be demonstrated. Yet, that request is so specific that I doubt there would be any tutorial with such a demonstration.

The Tiny SA would need to be in the tutorial naturally, but the SR-955HPC wouldn't. There are a number of higher-end radios that have a clarifier dial, (maybe by another name, but the same adjustment capability). Perhaps you could give a demo of that.

Also, since it's been some time since you posted this video, is it possible that you could demonstrate an example of how to connect an external signal function generator, (SFG), to the Tiny SA? I know that the Tiny SA has a relatively limited SFG built into it, but I read somewhere, (or happened on a video), that mentioned being able to connect an external SFG to the Tiny SA if not for simply calibrating the Tiny SA's accuracy, no?
Thanks again,
Rich

Hi Eric,

Looks cool. What about using the rtl-sdr dongle in the same manner with android?

Then using that to check your CB antenna, ...?

Spectrum analyser damn near killed them
