The tracking generator will give you only a scalar network analyzer - no complex measurements and no Smith Charts, no complex reflection coefficient and...... With the NANOVNA, you get it all except

Yes. Somehow I managed to forget that. Maybe in the future,? hint hint?

Question for those who own both a TinySA and the Ultra version: Are the cables physically different between the two models? Are the Ultra cables any different in length or diameter compared to the

Dave, Thank you for the 'very' informative link on the subject. I have been looking for a link on fully understanding the subject of Smith Chart use. Again, thank you with a "Happy New Year" to you

If you might wish to learn by doing, here is an excellent application. It's freeware at: http://www.ae6ty.com/ And an excellent tutorial at: http://www.w0qe.com/SimSmith.html Dave - W?LEV wrote:

There are also several good, simple to highly technical, tutorials on the Smith Chart in the archives on this group. They should be there as I've placed a few there. Dave - W?LEV wrote: -- *Dave -

The SA can be used to view the stereo sidebands from an FM broadcaster over the air. How this relates to alignment of a receiver separation is beyond me. There are specialized instruments that

Indeed, see spec in wiki -- For more info on the tinySA go to https://tinysa.org/wiki/

I understand that there are no plans for the signal generator in the TinySA (I have the Ultra version) to gain the functionality of modulating the carrier with an FM stereo composite signal. Is there

Erik, The seller was very helpful, sent a new unit quickly. New unit works well. seller was seasonshopping2016 on ebay. Thanks for your help Erik !!! -- Scott Nolde

I noticed that generator and SA Ultra use same connector. There is no tracking generator then.

Removed it. 600mVpp vs 130mVpp before (10MHz@-7dB coming from tinySA).

A first test will be to remove the switch and check if the signal level at the input jumps up to the level without any load. This will prove the ESD protection diode is not causing the problem -- For

OK, got this: https://ro.farnell.com/skyworks-solutions/as179-92lf/ic-switch-rf-spdt-0-02-3-0ghz/dp/1753762?st=AS179-92LF I hope I'm able to replace it and this is the source of the problem.

Yes. Its the input switch See the FAQ https://tinysa.org/wiki/pmwiki.php?n=Main.FAQ Scroll down to "tinySA ULTRA questions" -- For more info on the tinySA go to https://tinysa.org/wiki/

You are almost correct The switch is for the LNA but the signal path is bidirectional so if the switch is bad (e.g. creates 10dB loss) you will see this loss also when doing output -- For more info on

I'm playing around with the USB serial interface to simplify some pre-compliance tests. However, I can only get the live data out of the TinySA when the trace CALC is set to aver4 or quasi. The

I think (I may be wrong, as a beginner) that the switch is for IN/OUT. If that is the case, I can replicate the 10dB error by doing the reverse: generate a signal with the Ultra and read it on tinySA.
