NI PXI-5404
PFI 0 Connector
The PFI 0 connector is a bi-directional connector. As an input, the PFI 0 connector can accept a trigger from an external source that can start waveform generation. As an output, the PFI 0 connector can route out a signal from the following sources:
- CLOCK out
- Divided-down Sample clock timebase (20 MHz by default, derived from VCXO generated clock)
- REF IN connector
- PXI 10 (backplane clock)
- Software trigger
- PXI Star trigger
- PXI trigger bus (RTSI) lines
An input trigger should have values of VIH = 2.0 V and of VIL = 0.8 V.
The output trigger has values of VOH = 4.07 V and of VOL = 0.44 V into HiZ.
