    instrument handle

    The instrument handle that you obtain from the IviRFSigGen Initialize Node or IviRFSigGen Initialize With Options Node. The handle identifies a particular instrument session.

    Default: None

    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

    mode (None)

    Specifies the sweep mode applied to the output signal. The driver uses this value to set the IviRFSigGen>>Sweep>>Sweep Mode property. Defined Values: IVIRFSIGGEN_VAL_SWEEP_MODE_NONE - The RF output of the signal generator is a non-swept signal (Continuous Wave) using the frequency and power/level specified in the IviRFSigGen Configure RF.vi. IVIRFSIGGEN_VAL_SWEEP_MODE_FREQUENCY_SWEEP - The signal generator sweeps the RF output signal's frequency in an analog form (non-stepped). IVIRFSIGGEN_VAL_SWEEP_MODE_POWER_SWEEP - The signal generator sweeps the RF output signal's power in an analog form (non-stepped). IVIRFSIGGEN_VAL_SWEEP_MODE_FREQUENCY_STEP - The signal generator sweeps the RF output signals frequency in steps. IVIRFSIGGEN_VAL_SWEEP_MODE_POWER_STEP - The signal generator sweeps the RF output signals power level in steps. IVIRFSIGGEN_VAL_SWEEP_MODE_LIST - The signal generator uses two lists with frequency and power level values to sweep the RF output signals. Default Value: IVIRFSIGGEN_VAL_SWEEP_MODE_NONE

    datatype_icon

    trigger source (Immediate)

    Specifies the trigger used to start a sweep operation. The driver uses this value to set the IviRFSigGen>>Sweep>>Sweep Trigger Source property. Defined Values: IVIRFSIGGEN_VAL_SWEEP_TRIGGER_SOURCE_IMMEDIATE - The sweep system does not wait for a trigger of any kind, so it is running continuously. IVIRFSIGGEN_VAL_SWEEP_TRIGGER_SOURCE_EXTERNAL - The sweep is started with an external signal. IVIRFSIGGEN_VAL_SWEEP_TRIGGER_SOURCE_SOFTWARE - The sweep is started with a software programmable trigger. Default Value: IVIRFSIGGEN_VAL_SWEEP_TRIGGER_SOURCE_IMMEDIATE

    instrument handle out

    The instrument handle that you obtain from the IviRFSigGen Initialize Node or IviRFSigGen Initialize With Options Node. The handle identifies a particular instrument session.

    Default: None

    error out

    Error information.

    The node produces this output according to standard error behavior.

    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.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported

    Web Server: Not supported in VIs that run in a web application
