The Outline ET Series of computer-controlled motorized turntables that allow devices under test (DUT) to be positioned with a high degree of accuracy relative to the relevant data receptor(s) has two new members — ET50-3D and ET250R2-3D — both accomodating different speed and load requirements.
In suitable test environments, ET Series products are tools for measuring a range of different sorts of emissions, including electro-magnetic, optical, acoustic and others. They used in a multitude of industry sectors and are also employed by universities and research institutes for measurement of devices that including loudspeaker systems and tranducers, microphones, mobile comms devices, antennas, hearing aides, smart devices, solar panels, domestic appliances, medical equipment and more.
Both models offer a new Ergal aluminum hardware design that achieves military-spec mechanical resistance while reducing overall weight. In addition, they deliver a wider choice of rotation speeds with enhanced maximum handling loads and a simpler user interface with an input/output communications port based on TTL signals. The key to their accessibility, data acquisition and control is a network interface that fosters remote control via standard Ethernet protocols.
Each turntable has an individual IP address and the user connects this to an existing LAN to control it via the provided software or one of several third-party measurement systems. Control libraries for Matlab and Python are available; in addition, both devices are controllable by any software with Ethernet control capabilities, which facilitates automated polar measurements by integrating with measurement software suites that include Audio Precision, Audiomatica Clio, Listen Inc SoundCheck, Klippel, NTI and ARTA.
The new ET50-3D and ET250R2-3D are stated as capable of safely and accurately orienting loads of up to 200 kg (440 lbs) and 1000 kg (2200 lbs), respectively. Go here for more specifics.
