PXIe-5433 Theory of Operation

The PXIe-5433 generates analog output signals from digital waveform data at the CH connectors and routes triggers, events, and clock signals.

  • Onboard Memory—Stores the waveform data and generation instructions that you load into the PXIe-5433.
  • Waveform Generation Engine—Retrieves the waveform data and instructions from the onboard memory and triggers from trigger and event control using the sample clock.
  • Fractional Resampling and Filtering—Resamples (digital signal processing) and filters images.
  • Digital Gain—Applies digital gain to the signal.
  • DAC—Converts 16-bit digital waveform data.
  • Analog Output Path—Filters, amplifies, and attenuates the waveform data retrieved from the DAC.
  • Clocking—Creates and distributes the sample clock.
  • Onboard Reference Clock—Provides the default reference clock source.
  • Trigger and Event Control—Sends triggers and events to the waveform generation engine and routing matrix.
  • Routing Matrix—Routes triggers and events between PXI trigger lines and PFI terminals.
