DCP252A Series

The DCP252A is a precision 2-axis EL/AZ positioner primarily designed for radar module calibration. AZ and EL stages are stepper motor-powered worm-gear tables with 0.025 degree native resolution. Each axis has a home sensor which can be used to set pre-calibrated home positions. A high capacity tripod provides stability and increases weight capacity for the positioner.

What’s Included?

The standard D6025 package features a 2-axis positioner, our powerful DAMS Antenna Measurement Studio, precision RF cables and rotary joints, all tools and documentation, plus DUT mounting hardware. Everything is backed by 3-year warranty.

Educational discounts are available for students, teachers or staff of universities or technical schools.
