The service manual for the R&S FSH-244 Power Sensor provides guidance on performing performance tests, including zeroing, checking absolute measuring accuracy, and directivity, as well as instructions for setting up the necessary equipment for these tests. It also advises that adjustments requiring recalibration should be conducted by Rohde & Schwarz Central Service due to the specialized equipment needed.
Manual Overview
The service manual for the R&S FSH-244 Power Sensor provides detailed guidance on performing performance tests, including zeroing, measuring absolute accuracy, and directivity. Technicians are advised to conduct these tests at ambient temperatures between 18 °C and 28 °C, ensuring the device under test (DUT) is connected to the R&S FSH base unit for at least 30 minutes prior. The manual outlines the necessary equipment, such as spectrum analyzers, power meters, and signal generators, and emphasizes the importance of direct connections to minimize measurement errors. For zeroing, the signal generator should be off, and the R&S FSH should display a “Power Sensor Zero OK” message. Absolute measuring accuracy and directivity tests involve setting specific frequencies and power levels, with results recorded in a test report. Calibration and adjustments require specialized equipment and should be performed by Rohde & Schwarz Central Service. The manual does not provide board-level repair instructions, instead recommending sending sensors needing repair or recalibration to the manufacturer.
