The service manual for the Rohde & Schwarz SME covers setup, operation, and troubleshooting procedures, including specific modifications such as replacing capacitors and transistors to address issues like incorrect polarity and high temperature operation. It provides detailed instructions on modifying components, checking revisions, and ensuring proper calibration after modifications to maintain optimal performance and extend the equipment's lifespan.
Manual Overview
The service manual for the Rohde & Schwarz SME provides detailed guidance on troubleshooting, error diagnostics, calibration, and board-level adjustments for the signal generator. It emphasizes the importance of addressing specific modifications during repairs to ensure optimal performance. For instance, the manual highlights the need to replace capacitor C807 due to incorrect polarity, which requires connecting the positive electrode to ground and the negative to the -5V supply. Additionally, it advises replacing transistor V602 and installing a sheet metal cooler to prevent overheating, which can lead to error code “110, Output unleveled; ALC failure.” Calibration is necessary after these modifications, particularly for the Output Unit at 1.5 GHz. The manual also provides instructions for checking the revision of module OPU1 through the device’s utilities menu. The document underscores that only authorized technicians should perform these tasks to maintain safety and device integrity.
Quick Issues Covered
- Diagnose error code '110, Output unleveled; ALC failure'.
- Calibrate after replacing Output Unit 1.5 GHz components.
- Trace circuit issues from schematics for capacitor C807 polarity.

Safety & Warnings
To ensure safety and reliable operation, users must adhere to all instructions in the manual. Any intentional interruption of the protective conductor, either in the supply line or the device itself, is prohibited and may pose a danger. Extension cords and power strips should be regularly checked for safety. If the device lacks a power switch, the plug should serve as a disconnect device, and it must be easily accessible. Functional or electronic switches are not suitable for power disconnection. When integrating devices without a power switch into racks or systems, the disconnect device should be relocated to the system level. Local or national safety and accident prevention regulations must be observed during all work. Before servicing or opening the device, disconnect it from the power supply. Adjustments, part replacements, maintenance, and repairs should only be performed by R&S-authorized personnel. Safety-related parts should be replaced only with original parts, and a safety test must be conducted after each replacement. The device’s plug and socket should only be connected to outlets with a protective conductor. Additional safety instructions in the manual must also be followed.
