Hi team,

We want to tune the HF Oscillator "6.4 Tuning the HF Oscillator"(swra640.pdf).

We assume that the way to do it is:

・CMD_TX_TEST: Transmitter Test Command (23.3.3.1.8 in swcu117.pdf)

・MODE_CONF Register (Offset = FB4h) (9.1.1.4 in swcu117.pdf)

Is it correct way?

If it is, could you please tell me the specific method to do it?

If possible, the method without SmartRF studio is better for us.

Best regards,

Yuto

Hi Yuto,

Yes, without SmartRF studio, you'll have to modify the registers directly. I recommend using the rfCarrierWave example and a spectrum analyzer to determine the offset needed (if any). It will take some trial and error, but you just need to enable and modify the cap array using the MODE_CONF Register and make adjustments as needed.

Thanks,

Alexis
