AI Technical Summary

Technical Problem

In the existing technology, the test fixtures for dual filter switchers can only perform static measurements and cannot reflect their performance characteristics at different angles, resulting in low accuracy of test results.

Method used

A test fixture was designed, including a support, a test component, and a drive component. The drive component drives the support to rotate, simulating the working state of the dual filter switcher at different angles, thereby achieving multi-angle detection.

Benefits of technology

It improves the accuracy of test results for dual filter switchers, ensuring that their performance testing in complex environments is closer to real-world scenarios, enhancing the flexibility and comprehensiveness of testing, and preventing the limitations and misjudgments of single-direction testing.

Abstract

The application discloses a test tool, and belongs to the technical field of testing. The test tool comprises a support, a test assembly and a driving assembly. The support is used for fixing a double-filter switch. The test assembly is arranged on the support and is used for testing the double-filter switch. The driving assembly is connected with the support. The driving assembly can drive the support to rotate, so as to drive the double-filter switch and the test assembly to rotate. In the scheme, the driving assembly drives the support to rotate, so that the double-filter switch can rotate. Then, the double-filter switch in different angles in actual use can be simulated. The test of the double-filter switch is closer to the real scene, so that the double-filter switch can be detected at multiple angles. The accuracy of the test result of the double-filter switch is improved, and the quality of the double-filter switch is ensured.
