Power spectrum with Lora 32 (Lora Wifi BLE)

[boiteau]

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.

hi,

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.
