1 all "Inherent IVI Attributes" 
 "Attributes common to all IVI instrument drivers."

2 all "User Options" 
 "Attributes you can set to affect the operation of this instrument driver.\n"
 "    "

3 all "Range Check" RS_ATTR_RANGE_CHECK ViBoolean gs Boolean_values 
 "Specifies whether to validate attribute values and function parameters.  "
 "If enabled, the instrument driver validates the parameters values that you "
 "pass to driver functions.  Range checking parameters is very useful for "
 "debugging.  After you validate your program, you can set this attribute to "
 "VI_FALSE to disable range checking and maximize performance.\n"
 "    The default value is VI_TRUE.   Use the RS_InitWithOptions function to "
 "override this value.\n"
 "    "

3 all "Query Instrument Status" RS_ATTR_QUERY_INSTR_STATUS ViBoolean gs Boolean_values 
 "Specifies whether the instrument driver queries the instrument status "
 "after each operation.  Querying the instrument 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\n"
 "    The instrument driver can choose to ignore status checking for "
 "particular attributes regardless of the setting of this attribute.\n"
 "    The default value is VI_TRUE.   Use the RS_InitWithOptions function to "
 "override this value.\n"
 "    "

3 all "Cache" RS_ATTR_CACHE ViBoolean gs Boolean_values 
 "Specifies whether to cache the value of attributes.  When caching is "
 "enabled, the instrument driver keeps track of the current instrument "
 "settings and avoids sending redundant commands to the instrument.  Thus, "
 "you can significantly increase execution speed.\n"
 "    The instrument driver can choose always to cache or never to cache "
 "particular attributes regardless of the setting of this attribute.\n"
 "    The default value is VI_TRUE.   Use the RS_InitWithOptions function to "
 "override this value.\n"
 "    "

3 all "Simulate" RS_ATTR_SIMULATE ViBoolean gs Boolean_values 
 "Specifies whether or not to simulate instrument driver I/O operations.  If "
 "simulation is enabled, instrument driver functions perform range checking "
 "and call Ivi_GetAttribute and Ivi_SetAttribute functions, but they do not "
 "perform instrument I/O.  For output parameters that represent instrument "
 "data, the instrument driver functions return calculated values.\n"
 "    The default value is VI_FALSE.   Use the RS_InitWithOptions function "
 "to override this value.\n"
 "    "

3 all "Record Value Coercions" RS_ATTR_RECORD_COERCIONS ViBoolean gs Boolean_values 
 "Specifies whether the IVI engine keeps a list of the value coercions it "
 "makes for ViInt32 and ViReal64 attributes.  You call "
 "Ivi_GetNextCoercionInfo to extract and delete the oldest coercion record "
 "from the list.\n"
 "    The default value is VI_FALSE.   Use the RS_InitWithOptions function "
 "to override this value.\n"
 "    "

2 all "Instrument Capabilities" 
 "Attributes that provide information about this instrument driver and the "
 "physical resource it is using.\n"
 "    "

3 all "Number of Channels" RS_ATTR_NUM_CHANNELS ViInt32 g 
 "Indicates the number of channels that the specific instrument driver "
 "supports.  \n"
 "    For each attribute for which the IVI_VAL_MULTI_CHANNEL flag attribute "
 "is set, the IVI engine maintains a separate cache value for each channel.\n"
 "    "

3 all "Specific Driver Prefix" RS_ATTR_SPECIFIC_PREFIX ViString g 
 "The prefix for the specific instrument driver.  The name of each "
 "user-callable function in this driver starts with this prefix.\n"
 "    The prefix can be up to a maximum of eight characters.\n"
 "    "

2 all "Version Info" 
 "Attributes for obtaining information about the version of the instrument "
 "driver and the IVI engine.\n"
 "    "

3 all "Driver Major Version" RS_ATTR_DRIVER_MAJOR_VERSION ViInt32 g 
 "The major version number of this instrument driver.\n"

 "The minor version number of this instrument driver.\n"
 "    "

3 all "Driver Revision" RS_ATTR_DRIVER_REVISION ViString g 
 "A string that contains additional version information about this "
 "instrument driver.\n"
 "    "

3 all "Engine Major Version" RS_ATTR_ENGINE_MAJOR_VERSION ViInt32 g 
 "The major version number of the IVI engine.\n"
 "    "

3 all "Engine Minor Version" RS_ATTR_ENGINE_MINOR_VERSION ViInt32 g 
 "The minor version number of the IVI engine.\n"
 "    "

3 all "Engine Revision" RS_ATTR_ENGINE_REVISION ViString g 
 "A string that contains additional version information about the IVI "
 "engine.\n"
 "    "

2 all "Error Info" 
 "Attributes for error information.\n"
 "    "

3 all "Primary Error" RS_ATTR_PRIMARY_ERROR ViInt32 gs 
 "A code that describes the first error that occurred since the last call to "
 "RS_GetErrorInfo on the session.  The value follows the VXIplug&play "
 "completion code conventions.  A negative value describes an error "
 "condition.  A positive value describes a warning condition and indicates "
 "that no error occurred.  A zero indicates that no error or warning "
 "occurred. The error and warning values can be status codes defined by IVI, "
 "VISA, class drivers, or specific drivers.\n"
 "    "

3 all "Secondary Error" RS_ATTR_SECONDARY_ERROR ViInt32 gs 
 "An optional code that provides additional information concerning the "
 "primary error condition.  The error and warning values can be status codes "
 "defined by IVI, VISA, class drivers, or specific drivers.  Zero indicates "
 "no additional information.\n"
 "    "

 "An optional string that contains additional information concerning the "
 "primary error condition.\n"
 "    "

2 all "Advanced Session I/O"

 "These attributes control advanced capabilities that, typically, only "
 "driver developers use.\n"
 "    "

3 all "VISA Resource Manager Session" RS_ATTR_VISA_RM_SESSION ViSession g 
 "If a specific driver uses VISA instrument I/O, it passes the value of this "
 "attribute to the viOpen function during initialization.  The viOpen "
 "function returns an instrument I/O session, which the driver stores in the "
 "RS_ATTR_IO_SESSION attribute.\n"
 "    "

3 all "Instrument I/O Session" RS_ATTR_IO_SESSION ViSession g 
 "Specifies the I/O session that the specific driver uses to communicate "
 "with the instrument.\n"
 "    If a specific driver uses VISA instrument I/O, it passes the value of "
 "the RS_ATTR_VISA_RM_SESSION attribute to the viOpen function and sets the "
 "RS_ATTR_IO_SESSION attribute to the VISA session handle that viOpen "
 "returns.\n"
 "    "

3 all "Defer Update" RS_ATTR_DEFER_UPDATE ViBoolean gs Boolean_values 
 "Specifies whether to defer the actual updating of the physical instrument "
 "when you call one of the RS_SetAttribute functions.  The IVI engine "
 "performs all the deferred updates for the session when you call "
 "Ivi_Update.\n"
 "    Typically, it is not necessary to defer updates.  Deferring updates "
 "can be useful when the overhead of initiating instrument I/O is very high. "
 " By deferring updates, you can buffer multiple instrument commands into "
 "one I/O action.\n"
 "    Generally, only instrument driver developers use this attribute, and "
 "they do so on a temporary basis around a sequence of calls to "
 "Ivi_SetAttribute functions.\n"
 "    The default value is VI_FALSE.\n"
 "    "

3 all "Return Deferred Values" RS_ATTR_RETURN_DEFERRED_VALUES ViBoolean gs Boolean_values 
 "When you call one of the RS_GetAttribute functions on an attribute that "
 "has a deferred update pending, this attribute specifies whether to return "
 "the deferred value or the value that represents the actual state of the "
 "instrument.\n"
 "    Generally, only instrument driver developers use this attribute.  For "
 "particular attributes, the instrument driver can choose to ignore this "
 "attribute and always return the value that represents the actual state of "
 "the instrument.\n"
 "    The default value is VI_TRUE.\n"
 "    "

1 all "Miscellaneous Attributes" 
 "Additional Attributes."

2 all "ID Query Response" RS_ATTR_ID_QUERY_RESPONSE ViString g 
 "Returns the ID Query response string.  The instrument driver gets the "
