PXIe-5624 Specifications

Definitions

Warranted specifications describe the performance of a model under stated operating conditions and are covered by the model warranty.

Characteristics describe values that are relevant to the use of the model under stated operating conditions but are not covered by the model warranty.

  • Typical specifications describe the performance met by a majority of models.
  • Nominal specifications describe an attribute that is based on design, conformance testing, or supplemental testing.

Specifications are Warranted unless otherwise noted.

Conditions

Specifications are valid under the following conditions unless otherwise noted.

  • Internal Reference Clock source is used.
  • Dither level is set to high.
  • Digital downconversion (DDC) mode enabled.

Warranted specifications are valid under the following conditions unless otherwise noted.

  • 20 minutes warm-up time after the chassis is powered on and the LabVIEW Instrument Design Libraries for IF Digitizers software is loaded and recognizes the PXIe-5624. The warm-up time ensures that the PXIe-5624 and test instrumentation are at a stable operating temperature.
  • Calibration cycle is maintained.
  • Calibration IP is used properly during the creation of custom FPGA bitfiles.[1]
  • Chassis fan speed is set to high. In addition, NI recommends using slot blockers and EMC filler panels in empty module slots to minimize temperature drift.

Modes of Operation

The PXIe-5624 is a software designed instrument with a user-programmable FPGA.

The LabVIEW Instrument Design Libraries for IF Digitizers includes example FPGA images to use the PXIe-5624 in two modes of operation.

  • Digitizer Mode—Data from the ADC is stored directly into DRAM on the PXIe-5624 and fetched from the host. This data is not equalized or calibrated.
  • Digital Downconversion (DDC) Mode—Data from the ADC goes through signal processing before being stored in DRAM. The data is shifted in frequency, decimated, equalized, and calibrated using digital signal processing (DSP) on the FPGA.
