Abstract
The paper presents the structure of control section of measurement manipulator for acoustical tests in anechoic chamber. The specific of that kind of measurements brings up the need of measurement microphone positioning in many points of the measurement space accordingly to relevant standards. In most cases during the tests it is necessary to position the microphone in certain points on the hemisphere. The paper presents hardware structure and software to control the measurement manipulator accordingly to a specified algorithm. A modular construction of manipulator was chosen, which is composed of industrial turntable and two linear motion modules. That solution means that the device under test fixed on the turntable rotates in the range of 2π, and the measurement microphone moves on the track of one quarter of a circle.
