PXIe-4466 Specifications

Definitions

Warranted specifications describe the performance of a model under stated operating conditions and are covered by the model warranty. Warranted specifications account for measurement uncertainties, temperature drift, and aging. Warranted specifications are ensured by design or verified during production and calibration.

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 Typical unless otherwise noted.

Note Listed gain and phase mismatch specifications are valid for measurements made on channels on the same module. For measurements made on channels on different modules, the listed gain and phase mismatch specifications still apply, but are subject to the following conditions:
  • For gain matching, all modules must be properly warmed up and then self-calibrated. Refer to the Calibration section for the specified warm-up time.
  • For phase matching, all modules must be synchronized to a common timebase. To the listed specifications, add the following error: 360° × ƒin × clock skew. Refer to the Timing and Synchronization section for the maximum intermodule clock skew.
  • Gain specification applies only for two channels on the same board. For channels on different boards, gain mismatch is
    2 × Gain error + flatness

  • Gain specification applies only for two channels on the same board. For channels on different boards, gain mismatch is
    2 × Gain error + flatness
    .
