Disabling Unused Extensions

IviFgen Class Driver

When you call the IviFgen_InitiateGeneration VI, the class driver disables extension capability groups that the program does not use by setting properties of the unused extension group to values that disable that extension group.

  • If you do not use the IviFgenModulateAM extension group for a channel, this driver sets the IVIFGEN_ATTR_AM_ENABLED property to VI_FALSE for that channel.
  • If you do not use the IviFgenModulateFM extension group for a channel, this driver sets the IVIFGEN_ATTR_FM_ENABLED property to VI_FALSE for that channel.
