The CTIA test plan in the head and hand“talk mode” configuration specifies that the EUT not be in direct physical contact with the cheek of the head phantom, but rather, tilted away from the cheek by an angle of 6º. This “six degrees from touch position” is based on user studies and is intended to more realistically represent real-world operation of the EUT. Finding the correct “6º from touch” position against the head phantom may be difficult while the EUT is in the grasp of the hand phantom – in particular, the fingertips of the hand phantom may extend beyond the face of a thin EUT and act as an obstruction. The IXJ-010L/R and IXJ-011 mask spacers are available for the SAM head phantom, to assist with locating and maintaining the EUT in the desired “6º from touch” position. The mask is a 32 mm wide conformal strip, created by sweeping the surface of the head phantom through a 6º rotation about the ear. Direct EUT contact against the mask thus establishes the required 6º spacing away from the head, regardless of EUT form factor.
