Im working with LoRaWAN Signal using Chirp spread spectrum(CSS) Modulation Technique.
I would like to demodulate the LoRa signal using SA44B. LoRa Signal bandwidths is 125KHz, 250KHz and 500KHz & sampling rate around 50KHz to 100KHz.
I was aware that BB60C can able to demodulate LoRa since the real-time bandwidth is higher than the LoRa bandwidth.
We understand that CSS varies the frequency with time so Analog demodulation /zero span mode Is used to view the LoRa modulation.
Can you please confirm Whether our SA44B is compatible to demodulate LoRa signal in the bandwidth of 125KHz, 250KHz & 500KHz, if so what settings should I set in my Spike Software.

The Spike software does not have LoRa demodulation capabilities. You would need to use either a third party software platform that supports LoRa measurements (I am not aware of one) or use the API to retrieve the I/Q data and perform the measurement yourself. Additionally, the bandwidth of the SA44B is 250kHz, so you would at least have the bandwidth necessary for the 125 and 250kHz waveforms. I am not familiar with the LoRa standard and am not able to tell you if the SA44B is adequate for LoRa demodulation.
