Sustain Period
When using the sustain option, specify the desired sustain period in seconds. The
maximum value for the sustain period is 4294967295 times the sample period.
Sustain Conditional Mode
Select one of two available sustain modes to conditionally set the output channel state
based on the behavior of the input channel during the sustain period.
7.3.4 Triggered Zero Suppression
The Triggered Zero Suppression channel generates an output channel that zero
suppresses the input channel when a trigger condition is satisfied.
NOTE
The Triggered Zero Suppression computed channel is designed primarily to provide a
reset for quadrature decoder channel outputs when a triggering event occurs. For
more information on quadrature encoder inputs, see
“Pulse Counter” on page 111 .
Input Channel
The input channel data type must be 32-bit float, 32-bit integer or 32-bit unsigned.
Output Data Type
The output data type is the same as the input data type.
Trigger Channel
Select the input channel used to determine when to zero suppress the input channel
based on the trigger condition.
Trigger Mode
Select from three available trigger modes to specified the trigger channel behavior.
The available trigger mode options are below.
Sustain Mode Description
Unconditional Set the output to TRUE for the duration of the sustain period
regardless of the input channel behavior during the sustain
period.
While true Set the output channel to TRUE only while the input channel is
TRUE during the sustain period. Note that if the input channel is
FALSE when the sustain period begins, the output value will not
be set to TRUE effectively canceling the trigger. At the end of the
sustain period, the output value is set to FALSE and the search
for the next trigger start condition begins.
Trigger Mode Description
When TRUE Suppress when the trigger channel is TRUE.
On FALSE-TRUE edge Suppress when the trigger transitions from FALSE to TRUE.
On TRUE-FALSE edge Suppress on the sample after the trigger channel transitions from
TRUE to FALSE.
