Dear Ladies and Gentlemen,
we are using the CLRC66303 chipset and we want to reduce the transmission power.
We cleared the Cwmax bit and set_cw_amplitude value (TxAmp) to 3 (-1000mV). This does not changed the power consumption of the reader nor does it reduce the output voltage on the Tx1 pin.
Questions:
1. Are our assumption wrong, that set_cw_amplitude should change the transmission amplitude?
2. What is purpose of set_cw_amplitude?
3. Are there any other possibilities of reducing power?
Best Regards
Stefan
Hi @stefanmueller ,
The set_cw_amplitude value (TxAmp) does adjust the transmission amplitude, please see my test result from CLEV6630B board with Cockpit 5.8. The probe takes place right after the EMC filter.
set_cw_amplitude = 0
set_cw_amplitude = 3
If the power is still a little bit high, you may try to tune the antenna with a higher impedance.
Hope that helps,
Have a great day,
Kan
