Product Description
The NDZT-7.0-HP and NDZT-0.6-HP are high-precision turntables engineered for demanding EMC and OTA testing environments. Both models are built in compliance with MIL-STD-461G (RE102, CE102) and MIL-STD-810G, ensuring excellent electromagnetic compatibility, mechanical durability, and accurate DUT positioning. The NDZT-7.0-HP features a 7-meter stainless steel platform with a 10-ton load capacity for heavy-duty systems, while the NDZT-0.6-HP offers a compact 0.6-meter aluminum platform ideal for testing smaller wireless devices.
These turntables address common testing challenges such as inconsistent angular positioning, electromagnetic interference, and manual realignment delays. By providing stable 360° motion with minimal EMI, they help ensure reliable, repeatable measurements for both radiated emission and antenna performance evaluations.
Compared to conventional turntables, our NDZT series stands out for its shielded motor control system, low-profile structure for better chamber integration, and customizable interfaces for synchronized testing with antennas or probes. The precision gear system also enables smoother, low-noise rotation even under high loads.

Typical Applications
The OTA Turntable enables precise rotation of wireless devices during over-the-air (OTA) testing, ensuring consistent orientation and accurate measurement in anechoic chambers.
For EMC compliance and susceptibility assessments, the OTA Turntable provides stable and repeatable positioning, minimizing test variability caused by manual adjustments.
The OTA Turntable supports accurate antenna pattern measurement by allowing fine angular control, critical for characterizing radiation performance across all axes.
When testing heavy machinery or vehicles, the OTA Turntable offers high load capacity and smooth rotation, ideal for full-system EMC evaluations in large-scale setups.
