Synchronizing Modular Instruments with Homogenous Triggers

1. Open several modular instrument sessions and configure any required properties on the individual instruments.
2. Create a TClock object.
3. Access the DevicesToSynchronize property on the TClock object. The TClock object exposes the collection present in TClock.
4. Add the modular instrument objects through the Add method exposed on the TClockSynchronizableDevicesCollection.
5. Call ConfigureForHomogeneousTriggers exposed on the TClock object. This call will configure the modular instrument devices present in the collection held by the TClock object for homogeneous triggers.
6. Call the Synchronize method exposed on the TClock object. This call will align the sample clocks and triggers of the modular instrument devices present in the DevicesToSynchronize collection.
7. Call the Initiate method exposed on the TClock object. This call will Initiate the synchronized acquisition/generation on the modular instrument devices present in the DevicesToSynchronize collection.
