Chapter 20 Triggering Modes

19-2

Pci55xx Series Trigger and Buffer Considerations:

Depending on the number of Buffers and Cycle Mode specified, triggering maybe a continuous or single

cycle process for the “PRE_TRIG” and “ABOUT_TRIG” Modes. Because multiple buffers are available,

each buffer is considered individually in these trigger modes. Once a buffer completes, ADLIB moves on

to the next buffer and the whole triggering method begins again on that buffer and continues until all the

buffers are complete, or if in AL_CONTINUOUS CYCLE mode wrap to the first buffer and begins all

over again.

Returns:

On success ERRNUM is set to 1, otherwise ERRNUM contains the last error code that occurred during the

call.
