niRFSG_ConfigureIQEnabled [OBSOLETE]
C Function Prototype
ViStatus niRFSG_ConfigureIQEnabled (ViSession vi, ViBoolean enabled);
Purpose
Configures the NI-RFSG device to apply I/Q (vector) modulation to the RF output signal. I/Q modulation must be enabled in order to generate any arbitrary (non-sine) waveform; if I/Q modulation is disabled, a sine tone is always generated, regardless if an arbitrary waveform is written. The NI-RFSG device must be in the Configuration state before calling this function.
 |
Note This function is obsolete. Use the NIRFSG_ATTR_GENERATION_MODE attribute to enable I/Q modulation instead. |
Upon device initialization, or calling the niRFSG_reset function or the niRFSG_ResetDevice function, I/Q modulation is disabled.
Parameters
| Input | ||||||
| Name | Type | Description | ||||
| vi | ViSession | Identifies your instrument session. The ViSession handle is obtained from the niRFSG_init function or the niRFSG_InitWithOptions function and identifies a particular instrument session. | ||||
| enabled | ViBoolean | NI-RFSG sets the NIRFSG_ATTR_IQ_ENABLED attribute to this value. Defined Values:

Return Value
| Name | Type | Description | ||||||||
| status | ViStatus | Returns the status code of this operation. The status code either indicates success or describes an error or warning condition. Examine the status code from each call to an instrument driver function to determine if an error occurred.
To obtain a text description of the error code, call the niRFSG_GetError function. The general meaning of the status code is as follows:
