The Sony/Philips Digital Interface (SPDIF) connectors are in line with IEC
60958-3:2010 Consumer.
Connector selection
Whether AF 1 or AF 2 / SPDIF-L or SPDIF-R are used, depends on the instance (1 or
2) of the audio application and on the sub-instrument configuration of the instrument
(all resources in one sub-instrument or instrument split into two sub-instruments), as
shown in the following table.

3.1.2 Test Setup for Audio Measurement and Generator
The scenario "Audio Measurement and Generator" generally involves both an audio
generator and an audio measurement. The generator provides an audio signal at an
AF OUT or SPDIF OUT connector. The signal is routed to the DUT, passes the DUT
and is routed back to an AF IN or SPDIF IN connector. Then the signal is analyzed via
the audio measurement. The generator and the measurement are coupled, so that the
measurement knows the generator settings and thus the properties of the generated
signal.
A typical use case would be to analyze the frequency response of an amplifier.

You can freely combine analog and digital applications. You may for example couple
an analog generator and a digital measurement to test an A/D converter, or vice-versa
to test a D/A converter.
