I have both the standard and Ultra versions of the TinySA.? Both incredibly useful tools.? I recently became aware that the Ultra has built in ability for noise figure measurements on LNAs.? Purely

Not to mention 1 port handles it's whole frequency range... Get an ultra?!

The Ultra is much better for doing Bessel nulling, its resolution bandwidth is much narrower. Gary W9TD

First of all I must explain that I am pretty much a newbie when it comes to spectrum analyzers and I apologize if the answer to my question should be obvious. I have a TinySA and I've been working on

I am starting this new thread because the old thread below is locked: /g/tinysa/topic/possible_design_issue_with/109589683 Yesterday, the earphone jack on my 2-year old TinySA

I agree!

No, 82 is not "old". 82 is "wise". Dave -

ALL, I'm GUILTY of continuing an OFF topic thread.? Sorry.? Is 82 old or .........? Remain WELL & be *SAFE! *Robin **- - - - - - - - - - - - - - - - - - - - -

Gotcha ya beat, Dave, I was born the day before Ruzevult DIED. So that puts me up on the stack. Mike C. Sand Mtn GA

Yes, you could so long as you are at or below -30 dBm on the TinySA (I believe the spec is -26 dBm). Add 107 you dBm to get dBuV. Or more rigorously: dBV = dBm + 10 lob[Z] + 90 HOWEVER, the

Just a matter of spectral interpretation: Some time ago, I recognized that tinySA ultra offers a quasi peak display. But what I saw was something like attack and decay effects so to say over the time

at 77.5 years, I learn something new everyday!? But this topic makes my head hurt (in a good way)!? Thanks folks! -- Dan N1DH Middleboro MA

Thanks. That worked.

Once you have worked out how to do it and have some measurements it would be nice if you could share some experiences as this is for sure a more advanced topic for many users -- Designer of the

That's great to hear. The application of AF was the only outstanding uncertainty I had about the TinySA before I buy it.

You can enter the AFs and readings from the SA into separate columns within EXCEL and let that app do the arithmetic in a third column. In addition, you could have EXCEL plot that corrected data with

Yes Yes, Suggest to measure the exact frequency range of the antenna and store the trace on the SD, move it to a computer and edit the 450 values to reflect the antenna, move back to tinySA and load

Hi Erik, Thank you for the suggestion. Is the trace limited to 8 points linearly interpolated? This may work fine in a pinch, but ideally I someone upload the full table of AF measurements (there's

Using TRACE/CALC/TABLE TRACE you can create a trace containing a 8 point linear interpolation of the AF versus frequency. Suggest to use TRACE 4 for the table. Now you can use the TABLE TRACE as
