SMT391-VP User Manual

When the SMT391-VP receives a trigger, the SMT391 interface block gets activated
and starts capturing the samples sent by the ADC.

Connector J9 should be used to externally trigger the acquisition of both channels I
and Q.

Connector J10 should be left unconnected.

The following diagram is a graphical representation of the trigger structure and
