    NSI-SC-7701
 5-Axis Far-field Positioner System

DESCRIPTION

The NSI-SC-7701 is a 5-axis Roll over Upper-slide over Azimuth over Elevation over Lower slide positioner which is ideal for use in an indoor far-field measurement system.

CAPABILITIES

The 5-axis system can support a load of 400 lb (181 kg) on the Roll stage. An optional support post mounted on the the upper slide can be used to convert the Roll stage into an Elevation motion for the antenna. The 5-axis system 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 Azimuth and Roll stages also have 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.
