Information

• One trigger output for ADC hardware trigger and up to eight pre-trigger outputs for ADC trigger select per PDB
channel
• Trigger outputs can be enabled or disabled independently.
• One 16-bit delay register per pre-trigger output
• Optional bypass of the delay registers of the pre-trigger outputs
• Operation in One-Shot or Continuous modes
• Optional back-to-back mode operation, which enables the ADC conversions complete to trigger the next PDB
channel
