Data Acquisition Synchronization - 1

Data Acquisition Synchronization One of the strength of Elsys Data Acquisition Solution is its Scalability. A simple device may start with a 4-channel data acquisition card and may be expanded up to a multi-location, high channel count setup with more than 1000 inputs. Regardless of the size of the system, the Elsys synchronization technlogy provides sample precision time information and trigger distribution.

Inter-Device Synchronization All data acquisition cards from the TPCX and TPCE family can be synchronized by using a StarHub synchronization board. The StarHub acts as master clock reference and trigger distributor. Even when the device is build up from several boards, it behaves like one multichannel system. The synchronization precision is lower than 1 ns. This allows to make precise time measurements over different board inputs even at the fastest sampling rate of 240 MS/s. A Trigger on all Channels: All trigger events from any channel in the system gets synchronized through the StarHub...

StarHub Synchronisation Distributed Multi-Device Synchronization Ch 1 Sync Link The SyncLink 2.0 is the highest level of synchronization and allows to daisy-chain several SyncLink units together. The connection between them is established over fiber optical cables (FOC) allowing much larger distances between the DAQs than possible with the SyncLink SLB-8. The connection between the DAQ and the SyncLink 2.0 is still based on RJ45 CAT. 6 cables but its maximum length is expanded to 50 m while it is only 10 m for the SLB-8.

External Synchronization Elsys provides several possibilities to synchronize to or from other 3rd part measurement systems. Basically any synchronization technology which is capable of delivering a synchronized Pulse per Second (pps) signal can be used as master clock. The PPS signal must either connected to the StarHub PPS input or to the SyncLink 2.0 PPS input.
