1
For PFI 0 these characteristics apply when the line is configured as a digital input. They do not apply when configured as an
IRIG-B AM input.
2
Stresses beyond those listed can cause permanent damage to the device. Exposure to absolute maximum rated conditions for
extended periods of time can affect device reliability. Functional operation of the device outside the conditions indicated in
the operational parts of the specifications is not implied.
3
The NI PXI-6682H does not have star trigger lines.
