Driver Setup Options

    Last Modified: March 28, 2019

    The Driver Setup string is used with Initialize With Options to set the initial values for properties and attributes, respectively, that are specific to NI-RFSA.

    You can use the DriverSetup keyword in the option string input to complete the following tasks:

    • Specify your hardware device or external (non-National Instruments) device
    • Simulate hardware that is not present
    • Specify an NI-RFSA instrument driver FPGA extensions bitfile
    • Enable soft front panel (SFP) session access

    Driver Setup String Format

    The Driver Setup string uses the following format: DriverSetup=Tag:Value .

    To set multiple properties, separate tag and value pairs with a semicolon, as shown in the following string: DriverSetup=Tag1:Value1;Tag2:Value2;Tag3:Value3

    Specify Your Device

    Use the Driver Setup string to specify your hardware, as shown in the following table. In the following table, the portion of the string that follows the colon is the device name you see in Measurement & Automation Explorer.

    Use Example Driver Setup String Supported Hardware
    Specify a digitizer DriverSetup=Digitizer:my5622 PXIe-5663E/5665/5667/5668
    Specify an external digitizer DriverSetup=Digitizer:<external>
    Specify an LO source DriverSetup=LO:my5652
    Specify an external LO source DriverSetup=LO:<external> PXIe-5644/5645/5646, PXIe-5663E/5665/5667/5668
    Specify the resource name of the RF conditioning source DriverSetup=RFConditioning:PXISlot2 where PXISlot2 is an applicable RF conditioning device. PXIe-5667/5668
    Specify the resource name of the IF conditioning source DriverSetup=IFConditioning:PXISlot3 where PXISlot3 is an applicable IF conditioning device. PXIe-5667

    Enable Soft Front Panel (SFP) Session Access

    SFP Session Access allows you to pause your application and make changes to your device using the NI-RFSA Soft Front Panel. To enable SFP Session Access for your device, include the following tag and value pair in the Driver Setup string: SFPSessionAccess:1.

    Specifying an FPGA Bitfile

    The PXIe-5644/5645/5646, PXIe-5668, and PXIe-5820/5840 devices support loading custom bitfiles on to the onboard FPGA. To specify a bitfile, use the following tag and value pair in the Driver Setup string: Bitfile:filename.lvbitx, where filename.lvbitx is the file name of the bitfile you want to load.
