NI PXI-5404
REF OUT Connector


The REF OUT connector is an output connector that 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
  • PFI 0 connector
  • PXI trigger bus (RTSI lines)

The output clock has values of VOH = 4.07 V and of VOL = 0.44 V into HiZ. Rise and fall time for the output clock is 2.4 ns.
