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.
