Turntables and masts play a crucial role in the testing of devices under test (DUT) to determine their radiation or susceptibility. These tools allow for the rotation and height adjustment of the DUT to find the orientation of maximum radiation or susceptibility. This article delves deep into the intricacies of these tools, their significance, and how they are employed in various testing scenarios.

Key Takeaways:

  • Turntables and masts are essential tools for testing the radiation or susceptibility of a DUT.
  • They allow for precise orientation adjustments to find the maximum radiation or susceptibility.
  • Proper use of these tools ensures accurate and reliable test results.

Introduction to Turntables

Turntables are used to rotate the DUT, ensuring that every possible orientation is tested for radiation or susceptibility. They are designed to provide a full 360-degree rotation, allowing for comprehensive testing.


Types of Turntables

There are manual and automated turntables available. Manual turntables require a person to rotate the DUT, while automated ones can be controlled remotely, often from a computer or a dedicated controller.

Significance in Testing

By rotating the DUT, testers can determine the orientation that results in the maximum radiation or susceptibility. This is crucial for ensuring that devices meet regulatory standards and do not interfere with other electronic devices.

Understanding Masts

Masts are used to change the height of the DUT. This is important because the radiation or susceptibility of a device can vary depending on its height relative to the testing equipment.


Manual vs. Automated Masts

Like turntables, masts can be manual or automated. Manual masts require physical adjustment, while automated masts can be adjusted remotely.

Height Ranges

Typically, masts allow for height adjustments between 1 meter and 4 meters. This range ensures that the DUT can be tested at various heights to determine the optimal position for maximum radiation or susceptibility.

Combining Turntables and Masts

When used together, turntables and masts provide a comprehensive testing environment. The DUT can be rotated and its height adjusted simultaneously, ensuring that all possible orientations and heights are tested.


  • Why are turntables and masts important in testing?
    They allow for the precise orientation and height adjustment of the DUT, ensuring comprehensive testing for radiation or susceptibility.
  • Can I use a manual turntable and an automated mast together?
    Yes, you can combine manual and automated tools as needed. However, using both automated tools can streamline the testing process.
  • What is the typical height range for masts?
    Most masts allow for height adjustments between 1 meter and 4 meters.


Turntables and masts are invaluable tools in the world of electronic testing. By allowing for precise orientation and height adjustments, they ensure that devices are tested comprehensively for radiation or susceptibility. Whether you’re a manufacturer looking to ensure your products meet regulatory standards or a hobbyist interested in the intricacies of electronic testing, understanding the role of turntables and masts is crucial.
