I2s connector use for Input data

hello everyone. I’m a proud new owner of the QA403. I will be using it for acoustical signals, in which requires interfacing with sometimes digital microphones. I ask if there’s a chance in the future of the i2s Expansion connector to receive data from a i2s microphone for example.

Also, when measuring a DAC for example, How could I measure the phase when the output is from the digital interface. Does the generator outputs the signal from both the analog and digital at the same time?

Very recent acquisition, so maybe these are newbie questions.

Kind Regards.
