[AD9364] Tx filter config using Linux IIO

Category: Software
Product Number: ad9364


I have tried setting the Tx filters analog filters using the recommandations from this link :

I am setting out_voltage_rf_bandwidth to 200 kHz. Are there any indication of what is actually configured?

I have trouble caracterizing the resulting filter's cutoff frequency and slope. Below is the curve I got by generating sine waves at various frequencies with a filter bandwidth of 200 kHz.

As you can see, the 200 kHz (actually +/- 100 kHz, if I am not mistaken) is not the corner frequency. The slope is about -12 dBm/MHz.

Does any have any guidance on this?

Thank you very much.
