BIST Signal Generator
AD9361 and AD9364 have an internal signal generator which can be used to inject a signal into either the output of the Tx data port or the input of the Rx data port. This is useful when testing the connectivity of the Rx data port or the Tx RF output. It is a useful tool when debugging effects in the Tx chain of the AD9361. It allows the user to rule out the Tx data port as the source of issues, as it allows the user to generate a signal and inject it at the output of the Tx data port. Please see the attached document for more details.
