Description
Specifies whether the device is the master for synchronizing the shared Reference Trigger between multiple devices. The master device distributes the synchronized Reference Trigger to all devices in the system through the Reference Trigger distribution line.
When synchronizing the Reference Trigger, one device must always be designated as the master. When the device is configured as a master, it actively drives the Reference Trigger distribution line. When the device is configured as a slave, set the NIRFSA_ATTR_REF_TRIGGER_TYPE attribute to NIRFSA_VAL_DIGITAL_EDGE, and the NIRFSA_ATTR_DIGITAL_EDGE_REF_TRIGGER_SOURCE attribute to NIRFSA_VAL_SYNC_REF_TRIGGER_STR.
Refer to the Synchronization Using NI-RFSA and NI-RFSG topic appropriate to your device in the NI RF Vector Signal Analyzers Help for more information about device synchronization for vector signal transceivers.
Defined Values:
| VI_TRUE | The device is the master device for synchronizing the Ref Trigger. |
| VI_FALSE | The device is not the master device for synchronizing the Ref Trigger. |
Default Value: VI_FALSE
Supported Devices: PXIe-5644/5645/5646
