Bitmap Trigger
The Bitmap Trigger computed channel produces a logical output based on the match of the input bitmap channel and the user-specified bitmap mask. Use with an Anomaly Detect computed channel to generate a trigger when a defined anomaly is detected.

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.
- Bitmap check mode: Set the trigger mode for the computed channel.
- Any bit in mask set: If any bit in the specified bit mask is set, the output value is TRUE; otherwise it is FALSE.
- All bits in mask set: If all bits in the specified bit mask are set, the output value is TRUE; otherwise it is FALSE.
- Bit mask: Enter the desired bit mask as an integer from 1-15.
- Invert: If selected, the output logic defined by the Bitmap check mode is inverted. Note that using inversion can identify anomaly-marked data segments and output a trigger stream to gate out these data segments in other computed channels or DataModes.
