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

The Driver Setup string uses the following format:


To set multiple properties, separate tag and value pairs with a semicolon.


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:


where filename.lvbitx is the file name of the bitfile you want to load.

Note Note  Refer to NI-RFSA Instrument Driver FPGA Extensions for more information about using NI-RFSA instrument driver extensions for your device.

Enabling 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:


Specifying or Simulating a Device

Use the Driver Setup string to specify your hardware device or external (non-National Instruments) device, 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 (for example, my5652).

Use Example DriverSetup String Supported Devices
Specify a digitizer DriverSetup=Digitizer:my5622 PXI-5661, PXIe-5663/5663E/5665/5667/5668
Specify an external digitizer DriverSetup=Digitizer:<external>
Specify an LO source DriverSetup=LO:my5652 PXIe-5663/5663E/5665/5667/5668, PXIe-5840
Specify an external LO source DriverSetup=LO:<external> PXIe-5644/5645/5646, PXIe-5663/5663E/5665/5667/5668, PXIe-5840
Specify the resource name of the RF conditioning source DriverSetup=RFConditioning:PXISlot2

where PXISlot2 is an applicable RF Conditioning device.


Specify the resource name of the IF conditioning source DriverSetup=IFConditioning:PXISlot3

where PXISlot3 is an applicable IF Conditioning device.
Simulate an LO Source Simulate=1,DriverSetup=LO:5652

To specify a simulated device, use a string similar to this example: Simulate=1,DriverSetup=LOBoardType:PXIe
Simulate a digitizer Simulate=1,DriverSetup=Digitizer:5622
Simulate a downconverter Simulate=1,DriverSetup=Model:5603
Simulate multiple devices Simulate=1,DriverSetup=Model:5601;LO:5652;Digitizer:5622;LOBoardType:PXIe

When specifying or simulating multiple devices, separate them with a semicolon, as shown in the preceding string.
Simulate a vector signal analyzer Simulate=1,DriverSetup=Model:5665

Using External Digitizer/External LO Mode

As shown in the preceding table, you can specify an external LO or digitizer for use with your hardware modules. This configuration is known as external LO mode or external digitizer mode, respectively. When you are programming in either of these modes, some NI-RFSA features may not be supported. Refer to the Supported Devices section of each NI-RFSA VI, function, property, or attribute topic for information about supported features in these modes.
