Re: TinySA Ultra Menu-Tree Chart pdf file in landscape mode
Hello Kurt, Thank you very much, especially for info about calibration! One question about page 8 - is it true Ultra has 1 Hz RBW?  In the specs minimum RBW is 200 Hz... May be it mean 1 kHz?

Re: TinySA Ultra Menu-Tree Chart pdf file in landscape mode
Kurt,
I'm attaching a Word document with the corrections I made. I hope
it's helpful. The changes are in red, and should be
self-explanatory. I didn't make any changes to the last few pages,
but they're not required for basic use.
I'm sure the time and effort you and David put into this will be
appreciated by all users. While this would sure make a handy
pocket-sized booklet for use in the field, it's also perfect for use
with a laptop or tablet.

Hi
Erik
I anticipate SINUS also changed to SINE
Kind regards

The next release will use "ALTERNATE"
instead of "MULTI BAND"

Re: filter measurements with tinysa ultra
Hi Dave,
I have in the meantime 3 of them. TO be more precise 3 TinySAs
and 3 NAnoVNAs. :-)
It is so amazing? what can be measured with this little units!
In many cases they outperform some 20 years old heavy units,
degrading them to paperweights.
I have one TinySA all the time at my audio equipment repair
place, to test for rf oscillation.
The Ultra is with the NanoVNA 2 in my tool box for installation
and service of locking systems, to monitor the ISM band for
communication in this systems and to check the antennas.
The other two boxes are ión my RF test bench as handy tools to do
fast checks when repairing RF measurement equipment. I love the
fact that the TinySA has no grounding, so it dosn't make graund
loops.
To conclude, it is a good idea to have a lot of this little
helpers around :-)
All the Best,
Isidro

Thanks for all the replies and guidance.
Agreed - I think Erik has covered noise pretty well and
I'll be sure to follow his video and warnings (especially
total power). This seems like the best approach using the
Ultra.
Thanks for the note about a slow sweep and max hold. I
hadn't thought of that.
I haven't gotten around to getting a nanoVNA yet.
Maybe?it's time! It's definitely on my wish list.

You can also use a well calibrated

Can the tinysa ultra be used with
a tracking generator or in some other swept mode?
I see the video for the tinysa.
Also I see the ultra has an "LO" checkbox. Would
one use that LO out to drive a mixer or does the
ultra accept an external LO?
I'm interested in sweeping a
filter. I've seen the noise-generator based method
so perhaps that's the best approach.

Re: filter measurements with tinysa ultra
Hi Dave,
buy a TinySA Ultra for the measurements of the unit in service
and buy a NanoVNA for the pretuning and you have all what you
need.
All the Best,
Isidro

There is no sync output to step a tracking generator with the TinySA sweep. However there are two methods you can use to sweep your filter:
- Use a wideband noise source (use a safe level) and use the averaging function to get a smoothed plot
- Use an external generator and set it to very slow sweep speed ( in 10's of seconds) and then set tinySA to Max hold.? This will take some time but it will plot your filter response.

Re: TinySA Ultra Menu-Tree Chart pdf file in landscape mode
Kurt,
I don’t have Visio. I also don’t have experience with editing PDFs, but I could print the pages, mark them up by hand, then scan those. Would that work for you?

Re: Ultra Menu - Multi Band
That makes sense, but maybe ‘SEQUENCE’ would be more accurate?

New Ultra FW release: IMD measurement in multi band mode
New Ultra FW release Version V1.4070 Changes: - Loading default settings or a preset should now set/reset multi band. - SPAN parameter added in IMD measurement. SPAN=zero gives old behavior, SPAN>zero activates multi band with the requested SPAN per harmonic. Testing of this new feature is welcome as only by using it the bugs will be found. --
For more info on the tinySA go to https://tinysa.org/wiki/

Multi band and Measurements
The first measurement that will support multi band functionality is IMD (as it was the simplest) Signal generator was set to generate 2nd harmonic at -30dBc and 3rd up to 5th harmonic at -40dBc This is what you get without using the multi band option  The measurement range of the harmonics is limited by the noise floor You can improve the dynamic range by manually setting the RBW to 1kHz but the scan time will be 800 seconds Using multi band IMD measurement you only?enter the frequency of the fundamental (11MHz) and the span to be used when viewing the fundamental/harmonics (20kHz) and you get this in 2 seconds with an automatic RBW of 1kHz  More to come. --

Re: TinySA Ultra Menu-Tree Chart pdf file in landscape mode
I greatly appreciate Kurt's continuing work on this document I started at the beginning of this year.? I've been distracted for the last several weeks with some other projects (a new "toy" called a radiosonde) and our daughter's wedding coming up in a couple months.
Adobe Acrobat can rotate the pages to either landscape (which is how Kurt and I work with the document in Microsoft Visio) or portrait but I didn't realize the Acrobat Reader (not the full version) was unable to rotate the pages.
I'm glad I bought the TinySA Ultra last December. I had no idea at the time I bought it that I'd be using it to look at the 1.68GHz signal from a 49 year old radiosonde transmitter I found on surplusshed.com!? It only lasted about two minutes before an old paper capacitor apparently shorted out and wiped out the resonant cavity tube (or valve as they say in the UK).? Should have changed the capacitor out before applying power because now I just have a radiosonde paperweight!? Anyway, here is a screen shot of the signal from one meter away from the antenna before the capacitor damaged the tube.

Re: Ultra Menu - Multi Band

‘MULTI BAND’ seems a better description of the function than ‘ALTERNATE’ to me.
