Its good to know the tinySA will already have usable software when it is offered for sale.? Linux and Mac users will especially be happy to know that a cross-platform python derivative of Nano-Saver

The wiki has one page on the PC SW for the tinySA https://tinysa.org/wiki/pmwiki.php?n=Main.PCSW More to come

One more example added. Measuring IIP3 of the tinySA https://tinysa.org/wiki/pmwiki.php?n=Main.IIP3

The wiki is not hosted on groups.io but on a separate wiki server to ensure I do not run out of space.

Erik, See attachment.? When I select the Pages-Home button I was expecting to be taken to the Wiki Page ( https://tinysa.org/wiki/ ) but on my computer that doesn't happen. Herb

Which link fails and where does it point to? I failed to find the error.....

The left-hand Wiki menu doesn't seem to be linking correctly to " https://tinysa.org/wiki/ " - Herb

Wiki corrected for minimum input frequency

======================================================== Thanks for the clarification Erik, The " 0 MHz to 350MHz" specification on the Wiki page threw me off.? I think the HP 8566 series spectrum

To clarify more: The zero hertz peak is not caused by DC but by leakage of the 1st LO through the 1st mixer so technically it is not a zero hertz peak but a first IF peak. but given that it is

The zero hertz peak is indeed ignored The tinySA does not have DC coupling. Below 100kHz it starts to roll off and at 10kHz there is about 8dB attenuation which is not compensated. The input capacitor

Erik, In some of the measurement examples you provided the frequency sweep starts at 0 Hz.? In peak search functions does the tinySA ignore the internal 0 Hz signal and start its search to the right

To help understanding the measurement capabilities of the tinySA I added some measurement examples on the wiki https://tinysa.org/wiki/pmwiki.php?n=Main.Examples One set of wide scans and one set of

No problem. If any candidates drop out, I'm always willing to help.?I'm fed up taking the 8591C out in the car :-)Note also: Due to my long work schedule, I often don't check emails for 4 days in a

For now there are sufficient candidate testers.

Hi Erik Agree, removing any additional contribution on the two sideband frequencies from the two signal generators by using power combiners with isolation and other means such as isolators, will

But the internal generated IIP3 can not be higher then what is measured so I assume this measurement set a lower limit for the IIP3 of the tinySA, it could even be better. Correct?

Hi Erik I have a few comments/suggestions. I do not know how you test setup was, but there is a need to ensure the IIP3 level is not influenced by cross modulation between the two signal generators.

With FM modulation the zero span graph does not show the modulation but a simple trick can help. When you look at the close in spectrum of a FM signal using a wide but steep RBW the signal looks like

The tinySA can be used as a signal generator and in low output mode there are some options for modulation. Using the AM modulation to create a 10MHz signal with another tinySA in zero span mode it is
