PXIe-5113 Self-Calibration

You can self-calibrate the PXIe-5113 to mitigate measurement error.

Self-calibrating the PXIe-5113 corrects for the following:

  • Gain errors
  • Offset errors
  • Interleaving spurs
  • Intermodule synchronization errors

Self-Calibrating the PXIe-5113

Running self-calibration enables the PXIe-5113 to yield full performance over its operating temperature range and two-year external calibration cycle.

Before running self-calibration, warm up the PXIe-5113 for 15 minutes.

Note Warm-up begins after the chassis and either the controller or PC is powered and NI-SCOPE is loaded and recognizes the PXIe-5113.

PXIe-5113 modules are externally calibrated at the factory, but for optimal performance, use self-calibration in any of the following situations:

  • When the module is placed in a new system
  • When any module in the chassis is installed, uninstalled, or moved
  • When the controller or PC wakes from sleep or hibernate, is reset, or is power cycled
  • To periodically adjust for small performance drifts that occur with product aging
  • When the system temperature changes more than ±5 °C from the temperature of the previous self-calibration
  • Once 90 days have elapsed since the previous self-calibration
Tip You can use the nodes on the NI-SCOPEExternal Calibration palette to programmatically return the date and module temperature of the previous self-calibration. You can also view this information by selecting the device in MAX.
Self-calibrate the PXIe-5113 programmatically in NI-SCOPE or on demand in MAX.
OptionDescription
NI-SCOPE Use the Self Calibrate node to self-calibrate the module.
MAX Select the device in the Devices and Interfaces menu and click the Self-Calibrate button.
When the two-year external calibration interval expires, an external calibration is required to ensure performance within specifications over the subsequent two years.
