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" GF_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 GF_InitWithOptions function to "
 "override this value.\n"
 "    "

3 all "Query Instrument Status" GF_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 GF_InitWithOptions function to "
 "override this value.\n"
 "    "

3 all "Cache" GF_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 GF_InitWithOptions function to "
 "override this value.\n"
