Event Slice; Message Logger - HBM SomatXR CX23-R User Manual

CX23-R and EX23-R
NOTE
Typically, some messages or video frames will be stored before the defined pre-
trigger time and after the defined post-trigger time. The reason for this is a bit
complex, but in brief, it's much more efficient to process the message data in
blocks compared to processing one message (or one video frame) at a time. The
storage overhead will typically be very minimal.
Channel select: From the channels list, select the desired input channels for the
DataMode and click the appropriate arrow. Alternatively, drag and drop the desired
channels to the appropriate list.
4.6.4 Event slice
The Event slice DataMode™ stores a set of master channels and a set of slave
channels in the output data file. The set of master channels provides a sequence of
events, which are defined as state changes for any master channel. For each event,
the system stores data samples for all master and slave channels in the output data
file.
Store initial values: Select to always store the initial channel values at the start
of each test run.
Trigger mode: Select one of four available triggering options. Use triggering to
eliminate undesired segments of the input data stream before it is processed by
the DataMode.
Always on: Do not use triggering. Data storage is always on from the start of
o
the test.
Trigger: Data storage starts when the trigger channel becomes TRUE and
o
continues until the test run stops.
Gate: Data storage occurs when and only when the trigger channel is TRUE.
o
One shot: Store a single data sample when the trigger channel transitions from
o
FALSE to TRUE or if the trigger channel is TRUE on the first sample of any
run.
Trigger channel: Select the logical input channel for triggering — when using a
trigger option other than Always on. The trigger channel must have the same
sample rate as the selected input channels.
Channel select: From the channels list, select the desired input channels for the
DataMode and click the appropriate arrow. Alternatively, drag and drop the desired
channels to the appropriate list.
NOTE
The Event Slice DataMode provides a channel select tab for both Master
channels and Slave channels.
4.6.5 Message logger
The Message logger DataMode™ stores one or more message or video channels in
the output data file.
