DAQ-STC2
The DAQ-STC2 implements a high-performance digital engine for
NI 6232/6233 data acquisition hardware. Some key features of this engine
include the following:
•
Flexible AI and AO sample and convert timing
•
Many triggering modes
•
Independent AI and AO FIFOs
•
Generation and routing of RTSI signals for multi-device
synchronization
•
Generation and routing of internal and external timing signals
•
Two flexible 32-bit counter/timer modules with hardware gating
•
Static DIO signals
•
PLL for clock synchronization
•
PCI/PXI interface
•
Independent scatter-gather DMA controllers for all acquisition and
generation functions
