    slope (Positive)

    The internal trigger slope. The driver sets the IviPwrMeter>>Trigger>>Internal Trigger>>Internal Trigger Slope [IT] property to this value. Valid Values: IVIPWRMETER_VAL_POSITIVE - Sets the trigger event to occur on the rising edge of the trigger pulse. IVIPWRMETER_VAL_NEGATIVE (Difference) - Sets the trigger event to occur on the falling edge of the trigger pulse. Default Value: IVIPWRMETER_VAL_POSITIVE

    event source ("")

    The name of the channel to use as the internal trigger event source. The driver sets the IviPwrMeter>>Trigger>>Internal Trigger>>Internal Trigger Event Source [IT] property to this value. Pass the virtual channel name that you assign to the instrument in the Configuration Utility. 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. Virtual channel names are aliases for instrument-specific channel strings. The instrument-specific channel strings can differ from one instrument to another. Virtual channel names allow you to use and swap instruments without having to change the channel names in your source code. You assign a virtual channel name to an instrument-specific channel through the Configuration Utility. This control accepts virtual channel names you have assigned to the specific instrument you are using. It also accepts the instrument-specific channel names. Default Value: ""

    instrument handle out

    Instrument handle that you obtain from IviPwrMeter Initialize or IviPwrMeter Initialize With Options. The handle identifies a particular instrument session.

    Default: None

    error out

    Error information.

    The node produces this output 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.
