This document presents the EMC (Electromagnetic Compatibility) test report for the GEOSPACE TECHNOLOGIES CORPORATION's Pioneer device. The report focuses on radiated emissions testing conducted to ensure compliance with FCC 15.247 regulations. The tests were performed on May 12, 2025, and the report number is 106147890LEX-003.1a.
The report includes a series of test setup photos illustrating the equipment configuration during the radiated emissions measurements. These photos cover different frequency ranges, including 30MHz - 1GHz, 1GHz - 18GHz, 9kHz - 30MHz, and 18GHz - 40GHz. The test setup involves placing the Pioneer device on a turntable inside an anechoic chamber, with antennas positioned to capture radiated emissions at various frequencies. The photos provide a visual representation of the test environment and the positioning of the device under test.
The purpose of these tests is to verify that the Pioneer device meets the required limits for radiated emissions, ensuring that it does not cause harmful interference to other electronic devices. The results of these tests are crucial for obtaining regulatory approval and ensuring the device's safe and reliable operation.
