Hmmm... ?I ordered within an hour or so of when R&L posted the Ultra on their web site. ?Got charged immediately, too.

No ship notice for me, either.

Probably something I did in a previous life. ?Who knows?

So did Zeenko.

Hmmmm. 30+ years ago, when packet was big, I used a very similar approach to saving a TNC configuration, and then restoring it later. Thanks for the reminder!

This is 500Hz AM modulation depth 100%?



And this is 1% depth AM modulation to simulate the ability to see a -45dBc suppressed carrier at 500Hz distance

Hi guys,

I'm planning a purchase of the new Tiny SA Ultra and I'm looking at features that are important to me.? As a radio ham, transceiver builder and a proud owner of the original TinySA, I can say that one feature I would have liked in the TinySA is the ability to examine my SSB modulation (see this thread /g/tinysa/topic/74067552#143).? So, I'm encouraged by what I see in the specifications of the new Ultra, with its narrower RBW of 300Hz.

My question then is to anyone who has performed these kinds of measurements.? What are your impressions? Does it meet your expectations and are there any caveats to be aware of?

Kind Regards. D.

That's funny, eleshop.nl also had send me a shipping notification yesterday.

Seems both shops got the units same time. :-)

Hi Larry,

Yeah, I'm a visual guy, that's the reason for wanting the 'road-map' to the ultra. I'm working on one and it'll take some time as I will be modifying it from time to time to get it right.

Also, thanks for the various notes regarding the ultra. The test 3 failure was a real bone head one, duh, hook up the cable FIRST, go figure.

I am working on that pre-amp one of the guys suggested using the MMBT5089, wow, is that thing small, first I'm going to buy one of those microscope do-dads to even see the leads.

Being retired ain't for sissy's, it's hard work.

I talked (email) with someone at R & L last Friday. They said a shipment was coming in this week, but that it was sold out. I think he said the next shipment in was due in like 3 weeks (from last Friday? I don't know!)

He thought my order would be fulfilled this week, but I haven't gotten a ship notice so we'll see. :-)

Yep, got that same ship notice, a nice afternoon surprise.

They're already/still showing them out of stock, so hard to say if thats simply, they just haven't updated the online store, or they're still trying to get all backorders filled, and can't even yet do that.

R & L electronics sent an email that they shipped my TinySA Ultra today.
Guess they may Have them in stock now.

Martin,

Thanks for the clear, complete instructions on how to do this. Very much appreciated.

Thanks David, I'll check that software out.

Thank you.? I do have a NanoVNA and I'm at the point where I can get my antenna dialed in easily.? That much I know.? I also know the NanoVNA is much more capable than just that.? I'll investigate further.?

... is there a way to save preset configurations?

Alan?WA4SCA,

You can save and restore the configuration data with the help of the command line tool dfu-util, available as and as??from Erik's site.

Switch the device in DFU mode with "MENU / CONFIG / -> DFU / ENTER DFU" and save (upload to PC) it with:

? dfu-util --device 0483:df11 --alt 0 --dfuse-address 0x0801D000 --upload tinySA_config.bin

Chose the file name to store as you like, e.g. 'tinySA_config.bin' - this file shall not exist before otherwise the command fails. So you cannot overwrite already existing set-up data.

Switch to DFU mode and restore (download to tinySA) the saved config:?

? dfu-util --device 0483:df11 --alt 0 --dfuse-address 0x0801D000 --download tinySA_config.bin

For tinySA Ultra the config address in flash has changed, the command are (untested):

? dfu-util --device 0483:df11 --alt 0 --dfuse-address 0x0803C000 --upload tinySA_Ultra_config.bin

?dfu-util --device 0483:df11 --alt 0 --dfuse-address 0x0803C000 --download tinySA_Ultra_config.bin

If you make a small HW modification you can enter the DFU mode for tinySA simply by pressing the jog switch while turning power on.

Fleet,

One program you might like to know about is Satsagen:



As you gather more hardware, you may find its tracking generator/spectrum analyser capabilities quite handy.

Alberto /might/ be interested in adding some tinySA support, but I don't know whether he has the hardware or how busy he is!

Cheers,
David

Yes and no.
If you can put the RF explorer in max hold mode, you can let both devices independently sweep the target range and hope that after some time you have been able to catch all frequencies but this can take considerable time.
It is not possible to sweep in a synchronized way.
You could create a PC application that control the sweeping of both devices.

May I suggest you look into the nanoVNA family of VNA's as often a VNA is a much better tool than a SA with a tracking generator.

Greetings,

First off, I'm very, very new to spectrum analyzers.? I'm also a first year ham operator.? I found the web page showing how two TinySAs could be used, one for a tracking generator, the other acting as the spectrum analyzer.? I don't have two TinySA's yet (Ultra, I'm looking at you!) but I'd like to learn how the two combined work together.? Again, I'm a beginner here.

I bought my TinySA to use as a sacrificial instrument until I learned how to use one without blowing it up.? I also have an RF Explorer spectrum analyzer that goes to 6GHz and I read the manual before using it and learned of some of the pitfalls awaiting someone with no knowledge of power levels and how to attenuate them.? I know more now, at least in the safety department and I am looking to maximize the use of my tools.? My question is:? Can I use the TinySA as a tracking generator for the RF Explorer?? If I can then I'll proceed as shown by Erik and go from there.? i don't even know how/why a tracking generator is used but I wish to find out.? Do I have the tools to do so with these two spectrum analyzers?
