  • Page 28 Principles of Operation KPCI-3101 — KPCI-3104 Series User’s Manual Triggered scan mode KPCI-3101–4 Series boards support two triggered scan modes: internally-retriggered and externally-retriggered. These modes are described in the following subsections. Internally-Retriggered Scan Mode Use internally-retriggered scan mode if you want to accurately control both the period between conversions of individual channels in a scan and the period between each scan.

  • Page 32 2-12 Principles of Operation KPCI-3101 — KPCI-3104 Series User’s Manual Pre-trigger acquisition starts when you start the operation and stops when the board detects the selected post-trigger source, indicating that the first post-trigger sample was acquired (this sam- ple is ignored). If you are using internally-retriggered scan mode and the post-trigger event has not occurred, the board continues to acquire pre-trigger data using the internal retrigger clock to clock the opera- tion.
  • Page 33 KPCI-3101 — KPCI-3104 Series User’s Manual Principles of Operation 2-13 About-Trigger acquisition Use about-trigger acquisition mode (continuous about-trigger mode) when you want to acquire data both before and after a specific external event occurs. This operation is equivalent to doing both a pre-trigger and a post-trigger acquisition.
