PXI-5105 Specifications

Version:
    Last Modified: February 24, 2017

    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 expected performance met by a majority of the models.
    • Nominal specifications describe parameters and attributes that may be useful in operation.

    Specifications are Typical unless otherwise noted.

    Conditions

    Specifications are valid under the following conditions unless otherwise noted.

    • All filter settings
    • All impedance selections
    • Sample clock set to 60 MS/s

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

    • Temperature range of 0 °C to 55 °C
    • The PXI-5105 module is warmed up for 15 minutes at ambient temperature
    • Calibration cycle is maintained
    • The PCI/PXI/PXI Express chassis fan speed is set to HIGH, the foam fan filters are removed 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 available at http://www.ni.com/manuals.

    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. 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.

    Intermodule SMC Synchronization Using NI-TClk for Identical Modules

    Specifications are valid for modules installed in one NI PXI-1042 chassis. These specifications do not apply to PCI modules. Specifications are valid under the following conditions:

    • All parameters are set to identical values for each SMC-based module.
    • Sample Clock set to 60 MS/s.
    • All filters are disabled.

    Note  

    Although you can use NI-TClk to synchronize non-identical modules, these specifications apply only to synchronizing identical modules.
