    Amendment I Questions and Answers.docx
    The document addresses technical clarifications concerning the integration and replacement of power sensors within a specific instrumentation system. It confirms that the sensors are not used in conjunction with a conventional power meter but rather with an Interface Panel that processes the sensor data through an instrumentation amplifier and other electronic components to relay information to a CPU. The document specifies that the Interface Panel is essential to the overall system's functionality and should not be replaced alongside the sensors. When discussing data integration, the power sensors generate a DC voltage reflecting the average input RF power, which supports subsequent calibration processes for accurate measurements. This information is crucial for stakeholders involved in project proposals or procurement related to instrumentation systems, emphasizing the technical requirements and operational dependencies of the technology in question.
