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

I hope you remember us little people when you become rich and famous :) Can you share when you think the commercial version will be available?

Erik, I would love to test out this TinySA and have been with the project since December of 2019 and have a version built up like you did on protoboards. I have A LOT of test equipment at hand

Greetings Erik, A common problem for radio amateurs is the proliferation of modern day RFI sources that cause significant interference particularly to the HF bands. IMHO a portable low cost spectrum

Erik, Once you are ready to release the full list of console commands for the tinySA, I would like to see if I can translate? the python nanovna.py class library to the tinySA (tinysa.py?).? No

Hello, i can help you vs test tinySA My main job is the development, repair, maintenance of aviation communications systems. Therefore, I have the opportunity to test it on various equipment (compare

Hello, i can help you test tinySA My main work is development, repair, support of aviation communication systems (i not programmer, it my hobby, but i can help vs software) It is possible to check
