NOTES:

  • The STI plugin is a software option and requires the purchase of an iButton (APX-SW-STI) for measurement functionality. Download and installation of the plugin, without an iButton, enables the measurement in demo mode only.
  • APx STI Plugin v1.1 requires v4.2.1, v4.3 or v4.4.2 of APx500 audio test software. (For versions 4.5 or later of APx500 audio software, please use APx STI v2.0.)
