Or use a SDR receiver as a poor man SA. You can see modulation sidebands and splatter very well in the waterfall display. You can use really small BWs. Regards, Ignacio EB4APL -- El software de

To measure close in products you need a much narrower RBW typical is 30-100hz, maybe 300hz.? You also need to insure the carrier if any is not overloading the input of the SA. If true SSB source and

Your expectation on harmonics are dependent on the cause. For example input overload can do that, often you get other products like 3/2s as you have two signals generally the source and then the

It slowly occurred to me that I am doing this still too complicated and there is an even simpler measurement approach. (if this is too much details for this group feel free to shut me up) Using only

RBW means Resolution Bandwidth,e.g. the bandwidth of the narrowest filter before the power detector This implies you can not see anything inside a good SSB transmission but you are able to see if

Thanks Allison for the advice. As preparation for detailed performance measurements of a tinySA special using an high IIP3 mixer I?added two LC filters after the generators to remove the harmonics

AS the minimum RBW is 2.7kHz you can not "See" you modulation For that you best use a receiver and a PC with line in.

How close to a carrier I can get? Many Hams, educators and me would like to see and check their modulators. That is, can I see what does spectrum of? SSB with 1kHz modulation look like. Or 300Hz and

Perfect, thanks.

Minimum RBW is 2.7kHz

Sorry to ask, Will there be small bandwidth enough to analyse radio transmission? Voice and data. A quinta, 7/05/2020, 17:14, <erik@...> escreveu:

================================================== Eric, Just a line that you can set the value for and turn on and off.? Primarily used for quick visual indication of of how a measured signal

Would this line also induce some behavior? Like a pass/fail message? Or just a line?

Me too. Not now

I understand there needs to be a frequency limit somewhere, but just wondering why 960mHz.? I would love to see it go to maybe 1.5gHz. Keith

Erik, Another feature I hope you can add to a future wish list is a menu selectable reference line.? It would be a line drawn across the length of the display at a level chosen by the user that could

As the internal flash can endure above 10k write cycles I assume using the internal flash with a warning not to store too often is OK. Saving settings to one of the internal memory slots now also

If storage is a very important function, consider adding a WSON8-packaged SPI FLASH to the current PCB. some SPI connections need to be modified, and consider whether the current MCU has enough

Hi Erik, Digital scope functionality sounds good and thanks for your trace storage addition to the list! Tom, VA7TA
