Numeric Value | Data Type | Access | Applies To |

Remarks
The master device distributes the synchronized Start Trigger to all devices in the system through the Start Trigger distribution line.
When synchronizing the Start Trigger, one device must always be designated as the master. The master device actively drives the Start Trigger distribution line. For slave devices, set the NIRFSG_ATTR_START_TRIGGER_TYPE attribute to digital edge, and set the NIRFSG_ATTR_DIGITAL_EDGE_START_TRIGGER_SOURCE attribute to sync_script.
To set this attribute, the NI-RFSG device must be in the Configuration state.
Defined Values:
Value | Description |

VI_TRUE | The device is the master device for synchronizing the Start Trigger. |
VI_FALSE | The device is not the master for synchronizing the Start Trigger. |
Default Value: VI_FALSE
Supported Devices: PXIe-5644/5645/5646
