The Rohde & Schwarz service manual for the 6 GHz attenuator module covers the setup and operation of the attenuator, including detailed instructions for testing and adjusting the attenuator pads and control pulses. It also provides troubleshooting guidance for issues such as output level adjustment and output switch functionality, along with procedures for disassembly and reassembly of the module.
Manual Overview
The Rohde & Schwarz SME Service Manual, Chapter 3, provides detailed guidance on troubleshooting, error diagnostics, calibration, and adjustments for the 6 GHz attenuator module. The troubleshooting section emphasizes checking the control pulses for each attenuator pad using an oscilloscope, ensuring proper operation as per the provided diagrams. Error diagnostics involve verifying the ACFAIL signal to ensure the output switch opens correctly when the device is powered off. Calibration and adjustment procedures require connecting a network analyzer to measure the Voltage Standing Wave Ratio (VSWR) and transmission attenuation, ensuring they fall within specified limits across different frequency ranges. Adjustments are made using a set screw to minimize deviations from the desired attenuation values. Board-level guidance includes detailed steps for disassembling and reassembling the module, with caution advised to avoid damaging connector pins. External interfaces are described with specifications for signal levels and connections, ensuring proper integration and functionality within the system.
Quick Issues Covered
- Diagnose output switch issues using ACFAIL signal checks.
- Verify attenuator pad control pulses with oscilloscope.
- Use circuit diagrams for tracing attenuator pad connections.
