    NSI-SC-8007
Rotation Stage

DESCRIPTION

The NSI-SC-8007 is a high precision, heavy duty rotary positioner designed for a wide variety of antenna and RCS measurement applications. The stage can be used as an azimuth stage for far-field measurements or as a theta or phi rotation stage for spherical near-field applications. The stage includes an integral precision servo motor and motor driver that supports both single connection command (LAN) or step/direction control (TTL), an integral incremental and absolute encoder, a 26.5 GHz rotary joint and 24 contact slip ring assembly. Options are available for different slip ring, rotary joint frequencies, and encoder resolution. Contact NSI for additional information.

CAPABILITIES

The rotator can support a vertical load of up to 60,000 lb (27,216 kg) in azimuth configuration or 30,000 lbf (13,636 kg) when mounted in a roll configuration.
