4.8 Multi-Card Synchronization

PCIe/PXIe

-

5211 Series modules support master-slave synchronization mechanism to

achieve multi-card synchronous acquisition.

Master-Slave Synchronization

It will use 3 signals, Reference clock, Sync Pulse and Triger to achieve data
acqusistion simultaneously with multiple modules. First, the master module will
notice all of slave modules by routing the trigger signal through PXI trigger bus,
PXI_TRIG<0..7> when master module receives trigger. Second, we also need to make
sure every module to start the acquisition task in the same time, therefore we could
take advange of PXI system which can provide a synchronization pulse,
PXIe_SYNC100 to coordinate with the acquisition task of multiple modules.

Third, every module must use the same reference clock to keep pace with each
others and user can use PXIe_CLK100 which provides by PXI system as reference
clock.

The timing diagram is shown as Figure 53.

Figure 53 Master-Slave Synchronization

To enable the multi-card synchronization, configure the board as follows:

1. Set each task on different card as Master or Slave. Only one master is allowed.
2. Set the reference clock source of master card and slave card to PXIe_CLK100.

Refer to 4.5.1 for more information.
