Power spectrum with Lora 32 (Lora Wifi BLE)

Hy, I’m very suprised to see le power spectral when using Lora 32 with exemple Lora sender at 868 MHz running. As see below (snap of sdr#), the power activity in the band is very high, which is not a good caracteristics for a Lora transmission. An idea to improve this ?

Question have you over loaded the front end.when I look on a good spectrum analyser at say around -70 dbm I get the classics Lora spectrum curve that is nice and clean.


we have tested the code( exemple Lora sender at 868 MHz ) and works well.

OK, you are right. I tested with a better spectrum analyzer, and I get very nice traces (maxhold in yellow, instant in pink). Thanks very much.
