Hello,
We are currently developing with the nRF9151 and would like to request more information regarding GNSS SNR testing.
We have reviewed the documented GNSS functionality test procedure (GNSS functionality test), which utilizes the AT%XRFTEST (Set command) from the PTI modem. (Set command)
We are wondering how does the "<param0> RX signal power" parameters plays in the calculation of the results returned.
Would it be possible to run the same command (power) with a different signal in input? (more attenuated signal)?
I am not sure why the command output "antenna_power" level changes depending on the "expected power level", shouldn't it be a raw value?
Also I understand that the parameters is the expected power level at the module port, but why is it mentioned as GAIN? Is it because the GAIN applied on the signal is directly linked to the value given?
Would it be possible to have a "raw" level received?
Also, If we are confirming our RF path viability during production, is it recommended to use AFC on or off?
Thanks for you answers,
Arthur M
