AWR1642: How to bypass HPF1/HPF2 in radar API?

Part Number: AWR1642

HI champion,
In below post
https://e2e.ti.com/support/sensor/mmwave_sensors/f/1023/t/610630?tisearch=e2e-quicksearch&keymatch=HPF
We can find a attentuation curve when HPF1/HPF2 is bypassed, but we could not find this configuraiton in radar API. In rlProfileCfg_t, we can only configure the cutting frequency of HPF1/2 to a non-zero value.
Could we help to clarify is there a way to bypass one of the HPF?

Thanks,
Adam

Hello Adam,

The HPF1/2 are required and cannot be bypassed. This is the reason you do not find any API/control to bypass the HPF.

Thanks,
Raghu

Hi Raghu,

Thanks for the reply. Then why we have an attenutation curve which bypass HPF1 or HPF2 in below figure?

Thanks,
Adam

Hi Adam,
The bypass mode is an internal debug/test mode .
This is not open for the customers to use.

Thanks,
Raghu
