The service manual for the Rohde & Schwarz SMIQ02B/03B/04B/06B Vector Signal Generator provides detailed instructions for testing, repairing, and troubleshooting various modules, including the Option Modulation Coder SMIQ-B20 and the Options Data Generator SMIQ-B11 and Memory Extension SMIQ-B12. It includes procedures for self-testing, adjusting output levels, and diagnosing faults, emphasizing the replacement of faulty modules rather than component-level repairs.
Manual Overview
The Rohde & Schwarz SMIQ02B/03B/04B/06B service manual, Volume 4, focuses on the testing and repair of specific modules, including the Modulation Coder SMIQ-B20, Data Generator SMIQ-B11, Memory Extension SMIQ-B12, and Fading Simulator SMIQ-B14/B15. The manual provides detailed troubleshooting procedures, starting with a self-test that checks supply voltages, clock PLL, and RAMs. For diagnostics, the self-test is accessed via the UTILITIES menu, which identifies issues through a series of sequential tests. Calibration and adjustments involve setting I/Q output levels, power ramping, and delay adjustments using external clocks. The manual emphasizes that the module is a complex hybrid circuit, and detailed fault diagnosis at the component level is not feasible outside the manufacturing department. Faulty modules should be replaced and returned for detailed analysis. Essential tools include a dual-channel oscilloscope, pulse generator, and AC/DC voltmeter. The document aims to assist service engineers in identifying defective modules and provides guidance for supporting the manufacturing department in repairs.
Quick Issues Covered
- Diagnose power-up failures using selftest for supply voltages.
- Adjust I/Q output levels and offsets for calibration.
- Use schematics for circuit tracing and component location.
Overview
The service manual for the Rohde & Schwarz Vector Signal Generator models SMIQ02B/03B/04B/06B is divided into four volumes. It provides detailed instructions for testing and repairing various modules of the signal generator, including front modules, synthesis modules, and options like modulation coders and data generators. The manual includes function descriptions, servicing concepts, troubleshooting procedures, and self-tests for diagnosing and repairing faults. The document is designed to help service engineers identify defective modules, which are then sent to the manufacturing department for detailed diagnosis and repair.
