Use the acquisition trigger system to synchronize the digitized measurements with a trigger signal
from a number of trigger sources. Then use FETCh commands to return voltage or current information
from the acquired data.
The following figure illustrates the measurement acquisition process. This process applies to both
measurement triggers and external data logging. For an overview of the trigger system, refer to
Overview.
Capture pre-trigger data, if desired
The measurement system lets you capture data before, after, or at the trigger signal. As shown in the
following figure, you can move the block of data being read into the acquisition buffer with reference to
the trigger. This allows pre- or post-trigger data sampling.
