Settings for measure Lora signals


 

Hello there,?
?

I am having some strange behaviors between rx and tx in my personal project and have thought of using tinysa to better monitor what is going on.
The use will be for short/medium range so there is no need to measure signals below -90db at most.
?
My settings are BW500khz, SF5 and 868.0 Mhz, I have set tinySA center frequency 868, span 500Khz and I see perfectly the signals but, depending on the RWB I use, I get a RSSI or another, I would like to know what would be the appropriate settings or any advice to compare the RSSI between tinySA and LoRA modules.
?
Thanks!


 

To do pure power measurement at a known transmit frequency (or small range of frequencies) it may be better to switch to zero span mode and set the RBW to 850 kHz.
This will convert the tinySA into a narrow band scope.
This because with short transmission bursts a scan may partially miss the transmission.
In zero span mode you can monitor rather short bursts

Seems to work pretty good like you said?
Thank you so much!
