Generic parameters
- Name: Enter a name for the channel. The name must be unique and contain valid characters (invalid characters are single and double quotes, '\', '@', '#', '&', '<', '>').
- Collect: If selected, the channel data is written to the SIE data file during a test run.
- Description: Enter an optional detailed description of the computed channel.
- Input channel: Set the desired input channel. In the edit dialog, the channel sample rate is displayed in Hz.
- Measurand: Enter the quantity being measured or the type of measurement associated with the computed channel.
- Units: Enter the physical units of measurement for the computed channel.
- Trigger start mode: Set the start condition for the trigger.
- When true: Start when the input channel is TRUE.
- On false - true edge: Start when the input channel transitions from FALSE to TRUE.
- After true - false edge: Start on the sample after the input channel transitions from TRUE to FALSE.
Trigger delay setup
- Period: Enter the number of seconds after the trigger start to set the output channel state.
- Conditional mode: Set the output channel state based on the behavior of the input channel during the delay period.
- Unconditional: Set the output to TRUE regardless of the input channel.
Trigger sustain setup
- Period: Enter the number of seconds to sustain the output channel state. At the end of the sustain period, the output value is set to FALSE and the system waits for the next trigger start condition.
- Conditional mode: Set the output channel state based on the behavior of the input channel during the sustain period.
- Unconditional: Set the output to TRUE for the duration of the sustain period regardless of the input channel.
