FPGA VI:
–
Configure the CPTR period. The synchronization library ensures that the CPTR
period is the same on the host and the FPGA.

NI 5791 Specifications
Specifications are warranted by design and under the following conditions unless otherwise
noted:
•
Chassis fan speed is set to High. In addition, NI recommends using slot blockers and
EMC filler panels in empty module slots to minimize temperature drift.
•
The NI 5791 uses NI LabVIEW and LabVIEW FPGA software.
National Instruments RF devices are capable of acquiring and/or generating signals within
common Medical Implantable Communication System (MICS) frequency bands. NI RF
devices are tested and verified in manufacturing for several measurements. For more
