PXIe-5185 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.

Conditions

Specifications are valid under the following conditions unless otherwise noted.

  • For 50 Ω input channel, vertical range (Vpk-pk) set to 0.11, 0.2, 0.5, or 1
  • For 50 Ω input channel, vertical range (Vpk-pk) set to 0.11, 0.2, 0.5, 1, 2, 5, or 10
  • 1 MΩ input channel disconnected for 50 Ω input channel specifications, and 50 Ω input channel disconnected for 1 MΩ input channel specifications
  • Sample clock set to 6.25 GS/s or 12.5 GS/s
  • Onboard Sample clock locked to PXIe_CLK100 Reference clock
  • 0 °C to 50 °C ambient temperature
Note Early versions of the PXIe-5185 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:
  • PXIe-5185 module part numbers 199363x-0zL (where x is any letter and z is any number) only support 50 Ω input impedance.
  • PXIe-5185 module part numbers 152962x-0zL (where x is any letter and z is any number) support both 50 Ω and 1 MΩ input impedance

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

  • The PXIe-5185 is warmed up for 25 minutes at ambient temperature
  • Self-calibration is completed after warm-up period or when switching from an external Sample and/or Reference clock to the Onboard clock
  • Calibration cycle is maintained
  • The PXI Express chassis fan speed is set to HIGH, the fan filters are clean if present, and the empty slots contain PXI chassis slot blockers and filler panels. For more information about cooling, refer to the Maintain Forced-Air Cooling Note to Users document available at ni.com/manuals.
  • NI-SCOPE 3.9.6 or later instrument driver is used
  • External calibration is performed at 23 °C ± 3 °C

TClk Specifications

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.

Note You can only use NI-TClk to synchronize NI 5185 or NI 5186 devices to other NI 5185 or NI 5186 devices. These specifications apply only to synchronizing identical modules without using an external Sample clock.

Memory Sanitization

For information about memory sanitization, refer to the NI PXIe-5185/5186 Letter of Volatility, which is available for download from ni.com/manuals.

Calibration

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.
