TABLE OF CONTENTS Introduction W hich system for which configuration? 1. Define your requirements 2. onceptualize your configuration 06 C •• • • M VG advanced positioning systems • Rotary positioners • inear positioners/ L Floor slides • inear positioners / L X-Y-Z positioners • Model towers M VG - The Microwave Vision Group M VG - ORBIT/FR installations around the world

FROM ORBIT/FR TO MVG With over 30 years in the design and manufacture of advanced antenna positioning subsystems, Orbit/FR now contributes its expertise to the Microwave Vision Group (MVG), extending its know-how and participating in a full range of antenna test and measurement solutions. Today, as part of MVG, it continues to develop and innovate to meet the testing demands of an increasingly wireless and electronic driven world. From the legacy of the original positioning systems to our new low-profile, compact series, MVG continues to present quality engineered products with the most...

W hich positioning subsystem for which configuration? Positioners, an integral part of the system ➀ Define your requirements From the device to be tested to the real-estate available, several factors are to be considered when selecting equipment for a test facility configuration. The choice of the positioning subsystem to install is dependent upon these as a result. Antenna test systems are designed to perform direct measurements in far-field, direct far-field in compact range, or measurements in spherical, cylindrical, or planar near-field, possibly in combination. The directivity of the...

➁ Conceptualize a configuration Once requirements have been defined, the next step is conceptualization. Below are examples of a variety of possible positioner subsystems in different test configurations. This list is non-exhaustive. MVG provides quality, standard positioning subsystems, yet is also expert in customized solutions to meet your specific test requirements. EXAMPLE OF COMPACT RANGE MEASUREMENT CONFIGURATION Model tower - 2 Pol positioners, 1 AZ positioner Feed source Serrated-edge reflector EXAMPLE OF COMPACT RANGE MEASUREMENT CONFIGURATION AZ/EL medium duty positioner AZ/EL...

③ Select a positioning subsystem • Rotary Positioners • Linear Floor Slides • Model Towers • Controllers Once requirements are defined, and you have a conceptualized configuration, the next step is the selection of subsystems and components to be used. In the following pages, you'll find an overview of MVG positioning subsystems to guide you in your configuration & project planni

M VG advanced positioning systems MVG positioning systems provide the highest accuracy in motion and controllable velocity for the positioning of devices under test (DUT). Their robust and straight-forward design ensures maximum safety and reliability in operation. Fitted with DC motors, gear reducers, and high precision encoders or synchros, the systems continuously yield outstanding size and weight/ performance ratios. MVG’s advanced electromechanical technology brings additional precision to our positioning systems. Controllers with on-the-fly real-time discrete table triggering...

Rotary positioners A WIDE SELECTION ORBIT/FR offers a wide selection of rotary-based positioning products and various options to support the demanding needs of test ranges. Our rotary positioner solutions include industry standard single-axis and multi-axis platforms. Note that our azimuth positioners can be used as test chamber turntables such as for automotive antenna testing.* ORBIT/FR has extensive experience in designing rotary stage positioners and high-grade positioning subsystems for a variety of applications and organizations. These designs range from heavy duty, full-size aircraft...

L inear positioners/ Floor slides Linear positioners provide measurement flexibility by positioning the device under test (DUT) along a linear axis. Several can be combined to to increase freedom of movement and accuracy of positioning. They are to be selected according to application, size and weight of DUT, and necessary travel distance. Their durable construction ensures maximum reliability, low deflections, and trouble-free operation.
