6.3 Hardware
The acquisition section of the GEN3t is based on the successful and proven
GEN series Data Acquisition System.
In GEN3t the same concepts are used.

PCI
-
e/CPCI Backplane
GEN3t uses a combined PCI
-
e/CPCI backplane. The PCI
-
e (Peripheral
Component Interconnect Express) backplane can transfer data at very high
speeds to ensure the highest system throughput. The CPCI (Compact
Peripheral Component Interconnect) backplane can transfer data at high
speeds to ensure a high system throughput. The combined backplane supports
backward compatibility to support any GEN series acquisition cards and allows
new acquisition cards to use the faster PCI
-
e transfer speeds.
HINT/TIP
The CPCI backplane is the standard data storage bus. All acquisition cards
introduced to market before 2014 support only this backplane. The maximum
aggregate streaming rate for these acquisition cards is 200 MB/s.
Check the detailed specifications of the individual acquisition cards to see
whether it uses the fast data storage bus of the GEN3t if aggregate streaming
rates above 200 MB/s are required.
