Configures how the modulation accuracy (ModAcc) measurement synchronizes to the signal and the synchronization interval length.

Inputs/Outputs

  • cstr.png Selector String —

    Selector String specifies a selector string comprising of the signal name. If you do not specify the signal name, the default signal instance is used. The default value is "" (empty string).

    Examples:

    ""

    "signal::sig1"

    You can use the RFmxEVDO Build Signal String VI to build the selector string.

  • cgenclassrntag.png Instrument Handle In —

    Instrument Handle In specifies the RFmx session refnum. Instrument Handle In is obtained from the RFmxInstr Initialize NIRFSA VI.

  • ci32.png Synchronization Mode —

    Synchronization Mode specifies whether the measurement is performed from frame, slot, or symbol boundary.

    Frame (0) The frame boundary is detected and measurement is performed over the Measurement Length parameter value, starting at the offset from the frame boundary specified in the Measurement Offset parameter.
    Slot (1) The slot boundary is detected and measurement is performed over the Measurement Length parameter value, starting at the offset from the frame boundary specified in the Measurement Offset parameter.
    Arbitrary (2) The symbol boundary is detected and measurement is performed over the Measurement Length parameter value, starting at the offset from the frame boundary specified in the Measurement Offset parameter.

    The default value is Slot.

  • ci32.png Measurement Offset (slots) —

    Measurement Offset specifies the measurement offset to skip from the synchronization boundary. This value is expressed in slots. The synchronization boundary is specified by the Synchronization Mode parameter.

    For example, if the Synchronization Mode is set to Frame, ModAcc synchronizes to the first frame it finds. The measurement offset in slots is added after the boundary of this frame. The analysis is then started.

  • ci32.png Measurement Length (slots) —

    Measurement Length specifies the duration of the ModAcc measurement. The default value is 1.

  • cerrcodeclst.png error in (no error) —

    error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

  • igenclassrntag.png Instrument Handle Out —

    Instrument Handle Out passes a reference to your RFmx session to the next VI.

  • ierrcodeclst.png error out —

    error out contains error information. This output provides standard error out functionality.
