The Rohde & Schwarz SME service manual provides detailed instructions for setting up, operating, and troubleshooting the pulse generator module, including checking and adjusting pulse parameters such as delay, width, and repetition rate. It also includes procedures for diagnosing issues with the power supply and pulse outputs, as well as guidance on disassembling and reassembling the pulse modulator unit.
Manual Overview
The Rohde & Schwarz SME service manual focuses on troubleshooting, diagnostics, calibration, and board-level adjustments for the pulse generator option. Troubleshooting involves checking pulse generation in triggered and periodic modes, verifying power supply voltages, and inspecting short-circuit bridges. Error diagnostics utilize a multiplexer to monitor various DC voltages, including supply voltages and pulse outputs. Calibration involves comparing oscillator frequencies to a quartz-stable reference and adjusting as necessary. Board-level guidance includes disassembling the pulse modulator unit, which involves removing HF connections and shield covers, and using an adapter for measurement access. Reassembly requires careful attention to prevent misalignment of mounting bolts. External interfaces are detailed with specific pin functions and signal descriptions, ensuring proper connection and communication within the system. The manual provides comprehensive instructions for technicians to maintain and troubleshoot the pulse generator effectively, ensuring precise operation and reliability.
Quick Issues Covered
- Diagnose DC voltages using multiplexer D160 for offset detection.
- Check pulse delay and width calibration for out-of-tolerance issues.
- Troubleshoot no pulse in triggered mode using diagnostics in 7.4.3.

Operation
The manual provides detailed instructions for operating and adjusting the pulse generator. It describes the use of a gate array “PULSGEN” to generate pulses with adjustable parameters such as pulse delay, width, and repetition rate. The pulse generator can be triggered by an external signal or a command, and it includes a calibration mode for frequency comparison and adjustment. The manual also outlines the use of a serial interface for programming settings and a diagnostic feature for checking various voltages. Additionally, it provides specific steps for testing different operational modes, including triggered and periodic modes, and details the necessary equipment for these tests.
Troubleshooting & Error Codes
The manual provides troubleshooting guidance for the pulse generator option. It includes steps for diagnosing issues such as no pulse in triggered or periodic operation modes, and incorrect pulse delay and width. The manual suggests checking the power supply, reference, and short-circuit bridges, as well as performing calibration. Specific settings and expected results for testing different operational modes, such as triggered on rising or falling edge, double pulse, and periodic mode, are detailed. Diagnostic checks involve measuring specific voltages at different multiplexer channels to ensure proper operation.
