  Elevation over Azimuth Positioner


The NSI-SC-5670 is a high accuracy rotational positioner which is ideal for use as an elevation over azimuth stage for far-field measurements.


The rotator can support a vertical load of 2,500 lb (1,134 kg) and includes an integral precision stepper motor and motor driver. The stage interfaces to a standard NSI 2000 motion controller or can also be controlled directly by the customer using TTL pulse and direction control commands. The lower azimuth stage also has an integral 26.5 GHz rotary joint and 24 contact slip ring assembly to pass additional signals through the stages for other customer applications such as antenna control or for an additional positioner.
