    Opens a session for the supported hardware you specify, sets initial values of certain properties for the session, and returns a reference that identifies the instrument in all subsequent NI-RFSG nodes.

    datatype_icon

    resource name

    Resource name of the device to initialize.

    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

    option string

    Initial value of certain properties for the session.

    You can set the following properties using this input:

    • Range Check
    • Query Instrument Status
    • Cache
    • Coercions
    • Simulate
    • Driver Setup

    Option String Syntax

    The syntax for option string consists of the following relations:

    propertyName=value

    where

    • propertyName is the name of the property.
    • value is the value to which the property is set.

    Syntax for Setting Multiple Properties

    To set multiple properties, separate their assignments with a comma, as shown in the following option string:

    "RangeCheck=1, QueryInstrStatus=0, Cache=1, DriverSetup=AWG:pxi1slot4"

    Configuring the Driver Setup String

    1. Use the Driver Setup keyword in the option string to complete the following tasks:
      • Specify your hardware device or external (non-National Instruments) device
      • Simulate hardware that is not present
      • Specify an NI-RFSG instrument driver FPGA extensions bitfile
        spd-note-note
        Note

        Specifying an AE, AWG, or LO module in the Driver Setup string overrides any different existing association configured in MAX.

    2. Use the following format when configuring the Driver Setup string: Tag:Value
    3. When specifying or simulating multiple devices, separate them with a semicolon, as shown in the following string: DriverSetup=AWG:pxi1slot4; LO:pxi1slot7
    Table 1. Driver Setup String Examples
    Use Example Driver Setup String Supported Devices
    Specify an Amplitude Extender (AE) DriverSetup=AE:Dev1 PXIe-5654/5654 with PXIe-5696
    Specify a Waveform Generator (AWG) DriverSetup=AWG:Dev1 PXIe-5611, PXIe-5673E
    Specify an external AWG DriverSetup=AWG:<external>
    Specify a local oscillator (LO) DriverSetup=LO:Dev1
    Specify an external LO DriverSetup=LO:<external> PXIe-5611, PXIe-5644/5645/5646, PXIe-5673E, PXIe-5840
    Specify an NI-RFSG instrument driver FPGA extensions bitfile DriverSetup=Bitfile:filename.lvbitx PXIe-5644/5645/5646, PXIe-5820/5840
    Simulate a device DriverSetup=Model:model number; BoardType:type

    Refer to Simulating an NI-RFSG Device for more information about supported devices.

    datatype_icon

    id query

    Boolean value that indicates whether NI-RFSG performs an ID query.

    True NI-RFSG performs an ID query.
    False NI-RFSG does not perform an ID query.
    datatype_icon

    reset

    Boolean value that indicates whether the NI-RFSG device is reset during the initialization procedure.

    True The device is reset.
    False The device is not reset.
    datatype_icon

    session out

    Reference to your instrument session passed to the next node.

    datatype_icon

    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.
