Configuration 2
In this configuration, the DUT uses an external master clock as the reference clock. The

this configuration is analog to digital converter (ADC) evaluation.
Press on the FUNCTION panel to switch between audio generator or audio analyzer
mode, and press on the FUNCTION panel to switch to digital interface.
