Weizhong EMC Turntable: High-Precision Angular Positioning and Smooth Stepless Speed Control
Oct 14,2026
Weizhong EMC turntables deliver high-precision angular positioning and smooth stepless speed control, working in precise coordination with antenna systems to perform step-angle scanning, continuous rotation scanning, polarization scanning, and full-sphere radiation pattern testing. In EMC testing, angular positioning accuracy directly affects the consistency and repeatability of radiated emission testing, radiated immunity testing, antenna pattern testing, and electric field uniformity verification. Through precision angle control, Weizhong EMC turntables can perform small-angle stepping, fixed-point positioning, constant-speed rotation, and programmed scanning, meeting the positioning accuracy and motion stability requirements for EMC turntables set by domestic and international standards such as CISPR, IEC, ISO, and GB/T.
The turntables support stepless speed control, allowing rotation speed to be adjusted flexibly according to the test procedure. They can be used both for rapid positioning and for low-speed continuous scanning, avoiding the impact of abrupt speed changes on the test state of the equipment under test (EUT). In whole-vehicle EMC testing, automotive component EMC testing, communication equipment radiation testing, industrial equipment electromagnetic compatibility testing, consumer electronics certification testing, and third-party testing laboratory scenarios, Weizhong EMC turntables can stably carry miniature electronic instruments, in-vehicle electronics, communication modules, large industrial equipment, and new energy vehicle components, achieving 360° antenna scanning without blind spots.
With repeatable and traceable rotation control, Weizhong EMC turntables help reduce test uncertainty and improve the data consistency of radiated emission, radiated immunity, antenna calibration, whole-vehicle anechoic chamber testing, and EMC certification testing — helping laboratories improve testing efficiency and compliance pass rates.
