Tool/software:
Hello experts,
I am testing awr2243. the hardware is AWR2243Boost and DCA1000EVM.the config file of 2243 is attached.
the adc output is about +/- 200 with tx is disabled and rx gain is 48.
is the value normal in your experence? how can i decrease the value to lower than +/- 20 with the same conditions?
Best regards,
