    reference channel ("")

    Specifies the name of the reference channel to configure. The driver sets the IviCounter Phase Reference Channel property to this value. Users who want to achieve interchangeability should use a virtual channel name. The virtual channel name should be sufficiently specific to the test system such that it is unlikely to conflict with a physical channel name. Default Value: "" Notes: You can specify the reference channel name as a string variable or as a literal enclosed in double quotes.

    datatype_icon

    instrument handle

    The instrument handle you obtain from the IviCounter Initialize node or IviCounter Initialize With Options node. The handle identifies a particular instrument session.

    Default: None

    datatype_icon

    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

    input channel ("")

    Specifies the name of the start channel to configure. The driver sets the IviCounter Phase Input Channel property to this value. Users who want to achieve interchangeability should use a virtual channel name. The virtual channel name should be sufficiently specific to the test system such that it is unlikely to conflict with a physical channel name. Default Value: "" Notes: You can specify the start channel name as a string variable or as a literal enclosed in double quotes.

    datatype_icon

    frequency estimate (300 MHz)

    Specifies the estimated measurement phase. The driver sets the IviCounter Phase Frequency Estimate property to this value. Unit: hertz Default Value: 300000000.0

    datatype_icon

    resolution (1.0 Hz)

    Specifies the resolution of the phase measurement. It is the quantization size, or the smallest delta value that can be detected. The driver sets the IviCounter Phase Resolution property to this value. Unit: hertz Default Value: 1.0

    datatype_icon

    instrument handle out

    The instrument handle you obtain from IviCounter Initialize or IviCounter Initialize With Options. The handle identifies a particular instrument session.

    Default: None

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported

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