    instrument handle

    The instrument handle that you obtain from the IviUpconverter Initialize or IviUpconverter Initialize With Options Node. The handle identifies a particular instrument session.

    Default: None

    error in

    Error conditions that occur before this node runs.

    The node responds to this input according to standard error behavior.

    Standard Error Behavior

    Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

    error in does not contain an error error in contains an error
    If no error occurred before the node runs, the node begins execution normally.

    If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

    If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

    Default: No error

    datatype_icon

    frequency step start (500.0e3 Hz)

    Pass the start frequency of the stepped sweep. The driver uses this value to set the IviUpconverter Frequency Step Start [FST] property. Default Value: 500.0e3 Hz Notes: (1) If the stop frequency is less than the start frequency, the frequency decreases during the sweep.

    datatype_icon

    frequency step stop (5.0e6 Hz)

    Pass the stop frequency of the stepped sweep. The driver uses this value to set the IviUpconverter Frequency Step Stop [FST] property. Default Value: 5.0e6 Hz Notes: (1) If the stop frequency is less than the start frequency, the frequency decreases during the sweep.

    datatype_icon

    frequency step size (100.0e3)

    Pass the step size. The driver uses this value to set the IviUpconverter Frequency Step Size [FST] property. Default Value: 100.0e3 Notes: (1) The units are Hertz if the IviUpconverter Frequency Step Scaling [FST] is Linear and unitless (factor) if the IviUpconverter Frequency Step Scaling [FST] is Logarithmic.

    datatype_icon

    frequency step scaling (Linear)

    Pass the spacing of the steps. The driver uses this value to set the IviUpconverter Frequency Step Scaling [FST] property. Valid Values: IVIUPCONVERTER_VAL_FREQUENCY_STEP_SCALING_LINEAR - Enables linear scaling. IVIUPCONVERTER_VAL_FREQUENCY_STEP_SCALING_LOGARITHMIC - Enables logarithmic scaling. Default value: IVIUPCONVERTER_VAL_FREQUENCY_STEP_SCALING_LINEAR

    datatype_icon

    instrument handle out

    The instrument handle that you obtain from the IviUpconverter Initialize or IviUpconverter Initialize With Options VI. The handle identifies a particular instrument session. Default Value: None

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.

    If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

    If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported

    Web Server: Not supported in VIs that run in a web application
