    NSI-SC-5638
Azimuth Rotator

DESCRIPTION

The NSI-SC-5638 is a high accuracy rotational positioner which is ideal for use as an azimuth stage for far-field measurements or as a theta or phi rotation stage for a spherical near-field systems.

CAPABILITIES

The rotator can support a vertical load of 10,000 lb (4,535 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 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.
