This test instrument is used for the testing and calibration of sensors and gyroscopic instruments which require a precise and accurate angular velocity. The 1270VS rate table is an automated, variable speed table with a 21,600:1 speed range.

The front panel controls and liquid crystal display give the user full digital rate entry with multiple rate presets. The front panel consists of a power switch, LCD display, and four keys: run/menu, increase, decrease, and enter.

Full computer controlled automation can be accomplished with an RS-232 (standard) or IEEE- 488 (optional) interface. The closed-loop motion control system consists of a DC servo gearmotor, a controller, and an optical encoder.

The encoder is located on the high speed shaft of the gear motor to provide high resolution feedback for precise speed regulation. A gear train with electric clutches is used to select four different ranges.

The rate table can turn in both clockwise and counterclockwise directions. Clutches protect the gear train if large forces are applied to the tabletop. A four-point contact bearing is used to resist axial, radial, and moment loads while providing smooth rotation. Slip rings and a vacuum line are also standard features of the test table.
