Features
Description The MI-6910 Family of Planar Scanners offers scan dimensions from 3 to 80 ft (0.9 to 24.4m) and can be configured with a variety of options to improve accuracy, increase automation and simplify operation. Both vertical and horizontal scanners are manufactured with quality, state-of-the-art features. Both are designed to employ Z-axis correction if required. Horizontal scanners are generally custom designs that are based on customer requirements and standard proven design configurations. All of the standard sizes shown here can be adjusted to fit an exact scanning solution to any set of unique requirements. Applications
Absolute position accuracy is critical to most measurement applications. The MI-6910 Family of Planar Scanners is designed to make repeated measurements at critically accurate positions. A prime example is the position accuracy required for near-field antenna measurements. MI Technologies has designed positioners for operation at high frequencies without software correction. For higher frequencies, probe correction techniques developed by the National Institute of Standards and Technology (NIST) may be applied. Typically high gain directional antennas with low sidelobes are tested in the planar near field and even the smallest position errors and uncertainties can quickly degrade system dynamic range. To ensure the best possible measurement results, MI Technologies has implemented a robust mechanical design utilizing state-of-the-art drive system developments. When combined with our MI closed loop position control solutions, the MI-6910 scanner offers industry leading position accuracy of better than 0.002 inches (0.05 mm). MI Technologies has a long history of producing accurate and reliable positioning systems. Many of our positioners sold more than 30 years ago are still in use today providing accurate movement of antennas, probes, and other complex components. The MI-6910 Family of Planar Scanners is designed in this tradition to maintain alignment over long periods of time even when used around the clock. Specifications
Note 1: Higher frequencies can be attained when using less than the maximum scan area.
Ordering Information The above specifications are only representative of the standard product models listed. The MI-6910 Family of Planar Scanners is highly customizable and MI Technologies can readily optimize the size, frequency range, planarity and other performance factors to customer requirements. Because of this breadth of design flexibility, customers are encouraged to specify their need rather than the tightest tolerance available. The MI-6910 scanners are designed to work specifically with MI position controllers. Cables and position control units are ordered separately. If desired an installed RF path must be requested by ordering the appropriate option.
Configuration Options
