NI PXI/PCI-5411/5431
Power-Up and Reset Conditions


When you power up the computer, the NI 5411/5431 is in the following state:

  • The output is disabled and set to 0 V.
  • The Sample clock is set to 40 MHz.
  • The trigger mode is set to Continuous.
  • The trigger source is set to automatic (the software provides the triggers).
  • The digital filter is enabled.
  • Digital pattern generation is disabled.
  • Output attenuation remains unchanged from its previous setting.
  • The analog filter remains unchanged from its previous setting.
  • Output impedance remains unchanged from its previous setting.

When you reset the device using NI-FGEN or another application software, the NI 5411/5431 is in the same state as shown at power up with the following differences:

  • Output attenuation is set to 0 dB.
  • The analog filter is enabled.
  • Output impedance is set to 50 Ω
  • The PLL reference frequency is set to 20 MHz (NI 5411 only).
  • The PLL reference source is set to internal tuning (NI 5411 only).
  • The RTSI clock source is disabled (NI 5411 for PCI only).
  • The SYNC duty cycle is set to 50%.
