IviSpecAn Set Instrument From Marker [MKR] (G Dataflow)

Version:
    Last Modified: October 24, 2017

    Uses the IviSpecAn>>Markers>>Marker Position or IviSpecAn>>Markers>>Marker Amplitude property to configure the spectrum analyzer according to value of the InstrumentSetting parameter.

    For example, setting the Instrument Setting parameter to Frequency Center sets the center frequency to the value of the IviSpecAn>>Markers>>Marker Position property.

    This node may set the IviSpecAn>>Basic Operation>>Frequency Start, IviSpecAn>>Basic Operation>>Frequency Stop, or IviSpecAn>>Basic Operation>>Reference Level properties.

    If the IviSpecAn>>Markers>>Marker Enabled property is set to FALSE, this node returns the Marker Not Enabled error (0xBFFA2001). If the IviSpecAn>>Markers>>Marker Type>>Marker Type property is not Delta and the InstrumentSetting parameter is Frequency Span, the node returns the Not Delta Marker error (0xBFFA2002).

    instrument setting (Frequency Center)

    Specifies the instrument setting to be set from the marker position. Defined Values: Frequency Center - IVISPECAN_VAL_INSTRUMENT_SETTING_FREQUENCY_CENTER Frequency Span - IVISPECAN_VAL_INSTRUMENT_SETTING_FREQUENCY_SPAN Frequency Start - IVISPECAN_VAL_INSTRUMENT_SETTING_FREQUENCY_START Frequency Stop - IVISPECAN_VAL_INSTRUMENT_SETTING_FREQUENCY_STOP Reference Level - IVISPECAN_VAL_INSTRUMENT_SETTING_REFERENCE_LEVEL Default Value: Frequency Center - IVISPECAN_VAL_INSTRUMENT_SETTING_FREQUENCY_CENTER

    instrument handle out

    The instrument handle that you obtain from the IviSpecAn Initialize Node or IviSpecAn Initialize With Options Node. 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.
