The DSI Synchronization option (simultaneous acquisition) allows the user to acquire signals from both telemetry and hardwired sources aligned in time. The tight signal integration between implantable telemetry and hardwired sources also allows users to combine different study types (i.e. cardiovascular, respiratory, CNS) into a single study, where appropriate, enabling the user to save time and money.
When using the data synchronization card, telemetry signals from OpenART (PhysioTel Legacy and PhysioTel HD) will be synchronized with hardwired signals from the ACQ-16 or ACQ-7700 within 10 milliseconds (ms).
DSI does not have a specification if a sync card is not present. When the sync card isn’t used, the software relies on the computer clock to synchronize the signals. The quality of this clock can vary between computers; even between computers of the same make/model. Because of this, the level of synchronization may actually get worse with the duration of the acquisition.
The sole purpose of the sync card is to provide a high precision clock for this type of application.
The sync card is compatible with Ponemah v4.70 and greater. It is not compatible with Ponemah v6.x.
