RFmxVNA Initiate VI

Initiates all enabled measurements. Call this VI after configuring the signal and measurement. This VI asynchronously launches measurements in the background and immediately returns to the caller program. You can fetch measurement results using the Fetch VIs or result properties in the property node. To get the status of measurements, use the RFmxVNA Wait for Measurement Complete VI or RFmxVNA Check Measurement Status VI.

Inputs/Outputs

  • cstr.png Result Name —

    Result Name specifies the name to be associated with measurement results. Provide a unique name, such as "r1" to enable fetching of multiple measurement results and traces. This input accepts the result name with or without the "result::" prefix. The default value is "" (empty string), which refers to the default result instance.

    Example:

    ""

    "result::r1"

    "r1"

  • 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).

    Example:

    "signal::mysignal1"

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