Warranted specifications describe the warranted performance of a calibrated model under the stated operating conditions.
Characteristics describe values that are relevant to the use of the model under the stated operating conditions but are not covered by the product warranty.
Specifications are valid under the following conditions unless otherwise noted.
Early versions of the PXIe-5186 only support 50 Ω input impedance. Later versions support both 50 Ω and 50 Ω input impedance. To verify input impedances supported by your device, compare your device front panel with the diagrams at the end of this document. You can also check the device part number:

You can use the National Instruments TClk synchronization method and the NI-TClk driver to align the Sample clocks on any number of SMC-based modules in a chassis. Specifications are valid for any number of NI 5185 or NI 5186 modules installed in one PXI Express chassis, with all parameters set to identical values for each SMC-based module. For more information about TClk synchronization, refer to the NI-TClk Synchronization Help, which is located within the NI High-Speed Digitizers Help. For other configurations, including multichassis systems, contact NI Technical Support at ni.com/support.

Power-up calibration |
Automatically performed by the device at power-on to calibrate the gain, offset, and phase of the ADCs on the device. Typically takes 5 to 10 minutes to complete. |
Self-calibration |
Self-calibration is done on software command. The calibration corrects for gain, offset, triggering, and timing errors for all input ranges, excluding the External Trigger input channel (TRIG). Refer to the NI High-Speed Digitizers Help for information about when to self-calibrate the device. |
External calibration |
The external calibration calibrates the onboard references used in self-calibration, the input overload levels, and the external trigger levels. All calibration constants are stored in nonvolatile memory. |
Interval for external calibration |
1 year |
Warm-up time |
25 minutes |
