It includes all measurements of 3GPP TS 26.131/132 for the evaluation of digital and analog electrical interfaces.
UG TS 26 EL ITF Test (Code 60065) is an upgraded version of the automated test suite TS 26 131-32 (Code 6777). It includes all measurements related to 3GPP TS 26.131 and 3GPP TS 26.132 for evaluating digital or analog electrical interfaces. The electrical interfaces are defined and specified in Chapter 3.1 of 3GPP TS 26.131 and 3GPP TS 26.132. The signal path for the measurements is entirely electrical. Specific measurement equipment simulates a headset and connects to the electrical interface of the mobile device. Measurements conducted with this test suite evaluate the signal processing of the mobile device without being affected by the connected headset or acoustic interface. HEAD acoustics provides hardware and software solutions for performing the measurements of this test suite.
