Numeric Value	Data Type	Access	Applies to	Coercion	High-Level Functions
1050305	ViString	RO	N/A	None	None

Returns a string containing the logical name that you specified when opening the current IVI session.

You may pass a logical name to the niFgen_init function or the niFgen_InitWithOptions function. The IVI Configuration Utility must contain an entry for the logical name. The logical name entry refers to a virtual instrument section in the IVI Configuration file. The virtual instrument section specifies a physical device and initial user options.

Numeric Value	Data Type	Access	Applies to	Coercion	High-Level Functions
1050304	ViString	RO	N/A	None	None

Indicates the resource descriptor that NI-FGEN uses to identify the physical device.

If you initialize NI-FGEN with a logical name, this attribute contains the resource descriptor that corresponds to the entry in the IVI Configuration Utility.

If you initialize NI-FGEN with the resource descriptor, this attribute contains that value.

Numeric Value	Data Type	Access	Applies to	Coercion	High-Level Functions
1050203	ViInt32	RO	N/A	None	None

Returns the number of channels that the specific instrument driver supports. For each attribute for which IVI_VAL_MULTI_CHANNEL is set, the IVI Engine maintains a separate cache value for each channel.

Returns a brief description of the specific driver.

Numeric Value	Data Type	Access	Applies to	Coercion	High-Level Functions
1050302	ViString	RO	N/A	None	None

Returns a string that contains the prefix for NI-FGEN. The name of each user-callable function in NI-FGEN starts with this prefix.

1050513	ViString	RO	N/A	None	None

Returns a string that contains the name of the vendor that supplies NI-FGEN.

Numeric Value	Data Type	Access	Applies to	Coercion	High-Level Functions
1050551	ViString	RO	N/A	None	None

Returns a string that contains additional version information about NI-FGEN.

Numeric Value	Data Type	Access	Applies to	Coercion	High-Level Functions
1050511	ViString	RO	N/A	None	None

Returns a string that contains the name of the device manufacturer you are currently using.

Numeric Value	Data Type	Access	Applies to	Coercion	High-Level Functions
1050512	ViString	RO	N/A	None	None

Returns a string that contains the model number or name of the device that you are currently using.

Numeric Value	Data Type	Access	Applies to	Coercion	High-Level Functions
1050510	ViString	RO	N/A	None	None

Returns a string that contains the firmware revision information for the device that you are currently using.

Numeric Value	Data type	Access	Applies to	Coercion	High Level Functions
1150390	ViString	RO	N/A	None	None

Returns the revision letter of the module you are using.

Numeric Value	Data Type	Access	Applies to	Coercion	High-Level Functions
1050004	ViBoolean	R/W	N/A	None	None

Specifies whether to cache the value of attributes. When caching is enabled, NI-FGEN keeps track of the current device settings and avoids sending redundant commands to the device. Thus, you can significantly increase execution speed.

NI-FGEN can choose to always cache or to never cache particular attributes regardless of the setting of this attribute. Use the niFgen_InitWithOptions function to override the default value.

Defined Values

VI_TRUE	Caching is enabled.
VI_FALSE	Caching is disabled.

Default Value: VI_TRUE

Numeric Value	Data Type	Access	Applies to	Coercion	High-Level Functions
1050021	ViBoolean	R/W	N/A	None	None

Specifies whether to perform interchangeability checking and retrieve interchangeability warnings when you call the niFgen_InitiateGeneration function.

Interchangeability warnings indicate that using your application with a different device might cause different behavior. Call the niFgen_GetNextInterchangeWarning function to extract interchange warnings. Call the niFgen_ClearInterchangeWarnings function to clear the list of interchangeability warnings without reading them.

Interchangeability checking examines the attributes in a capability group only if you specify a value for at least one attribute within that group. Interchangeability warnings can occur when an attribute affects the behavior of the device and you have not set that attribute, or the attribute has been invalidated since you set it.

Defined Values

VI_TRUE	The signal generator performs interchangeability checking.
VI_FALSE	The signal generators does not perform interchangeability checking.

Default Value: VI_FALSE

Numeric Value	Data Type	Access	Applies to	Coercion	High-Level Functions
1050003	ViBoolean	R/W	N/A	None	None

Specifies whether NI-FGEN queries the device status after each operation. Querying the device status is very useful for debugging. After you validate your program, you can set this attribute to VI_FALSE to disable status checking and maximize performance. However, the effect on NI-FGEN is minor.

NI-FGEN can choose to ignore status checking for particular attributes regardless of the setting of this attribute.

Use the niFgen_InitWithOptions function to override the default value.

Defined Values

VI_TRUE	Enables NI-FGEN device status queries.
VI_FALSE	Disables NI-FGEN device status queries.

Default Value: VI_TRUE

Numeric Value	Data Type	Access	Applies to	Coercion	High-Level Functions
1050002	ViBoolean	R/W	N/A	None	None

Specifies whether to validate attribute values and function parameters. If enabled, NI-FGEN validates the parameter values that you pass to NI-FGEN functions. Range-checking parameters is useful for debugging. After you validate your program, you can set this attribute to VI_FALSE to disable range checking and maximize performance.

Use the niFgen_InitWithOptions function to override the default value.

Defined Values

VI_TRUE	Enables range checking.
VI_FALSE	Disables range checking.

Default Value: VI_TRUE

Numeric Value	Data Type	Access	Applies to	Coercion	High-Level Functions
1050006	ViBoolean	R/W	N/A	None	None

Specifies whether the IVI Engine keeps a list of the value coercions it makes for ViInt32 and ViReal64 attributes. Call the niFgen_GetNextCoercionRecord function to extract and delete the oldest coercion record from the list.

Use the niFgen_InitWithOptions function to override the default value.

Defined Values

VI_TRUE	The IVI Engine keeps a list of value coercions.
VI_FALSE	The IVI Engine does not keep a list of value coercions.

Default Value: VI_FALSE

Numeric Value	Data Type	Access	Applies to	Coercion	High-Level Functions
1050005	ViBoolean	R/W	N/A	None	None

Specifies whether to simulate NI-FGEN I/O operations. If simulation is enabled, NI-FGEN functions perform range checking and call Get Attribute and Set Attribute functions, but they do not perform device I/O. For output parameters that represent device data, NI-FGEN functions return calculated values.

Use the niFgen_InitWithOptions function to override the default value.

Defined Values

VI_TRUE	NI-FGEN simulates I/O operations.
VI_FALSE	NI-FGEN does not simulate I/O operations.

Default Value: VI_FALSE
