Initialize With Options (G Dataflow)
Creates a new session for the hardware, sets initial values of certain properties for the session, and sends initialization commands to reset all hardware modules to a known state necessary for NI-RFSA operation.
resource name
Resource name of the device to initialize.
Device Name Syntax
For NI-RFSA devices, the syntax is the device name specified in MAX. The typical default name for your device in MAX is PXI1Slot2. You can rename your devices by right-clicking the name in MAX, selecting Rename from the drop-down menu, and entering a new name. You can also pass in the name of an IVI logical name configured with the IVI Configuration utility.
Creating a New Session for a Vector Signal Analyzer
To create a new session for your vector signal analyzer, you must wire the downconverter resource name to this input.
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.
Default: No error
id query
reset
option string
Initial value of certain properties for the session.
You can set the following properties using this input:
Option String Syntax
The format of this string is "PropertyName=Value'" where PropertyName is the name of the property and Value is the value to which the property is set. To set multiple properties, separate their assignments with a comma.
| Property | Use | Valid Values | Example String Syntax |
|---|---|---|---|
| Range Check | Specify whether to validate property values and node parameters. | 0 (false), 1 (true) | "RangeCheck=1" |
| Query Instrument Status | Query the device status after each operation. | 0 (false), 1 (true) | "QueryInstrumentStatus=1" |
| Cache | Cache the value of properties. | 0 (false), 1 (true) | "Cache=1" |
| Driver Setup | Specify an FPGA bitfile, enable soft front panel (SFP) session access, or specify a device. | Refer to Driver Setup Options for more information about using the driver setup string, including valid values. | "DriverSetup=SFPSessionAccess:1;LO:my5652" |
| Simulate | Simulate I/O operations using NI-RFSA. | 0 (false), 1 (true) | "Simulate=1" |
session out
Reference to your instrument session passed to the next node.
error out
Error information.
The node produces this output according to standard error behavior.

Accessing the Device Session with the NI-RFSA Soft Front Panel
You can access the new device session using the NI-RFSA Soft Front Panel (SFP). Accessing the device session with the SFP can help you debug your code.
To enable SFP session access, create a new session for your device by wiring the following string into the option string input: DriverSetup=SFPSessionAccess:1.
To disable SFP session access, wire the following string into the option string input: DriverSetup=SFPSessionAccess:0.
