The Rohde & Schwarz SME operating manual provides detailed instructions on setting up the signal generator, including ensuring proper casing, ventilation, and voltage settings, as well as guidelines for switching the instrument on and off. It also covers troubleshooting procedures such as self-tests and error message identification, along with instructions for fitting options and performing necessary calibration routines.
Manual Overview
The Rohde & Schwarz SME Signal Generator operating manual provides detailed instructions for technicians on operating, troubleshooting, and maintaining the device. The manual emphasizes the importance of ensuring proper setup before use, including securing the casing and ensuring ventilation. The SME automatically adjusts to the supply voltage within specified ranges, and it is protected by fuses located in a draw-out holder. The device features a standby mode for maintaining frequency accuracy, especially when using the optional oven-controlled reference oscillator.
Troubleshooting involves a self-test upon startup and continuous monitoring during operation. If errors occur, an “ERROR” message appears, which can be further investigated using the [ERROR] key. Calibration is crucial for maintaining accuracy, with routines such as VCO SUM, LEV PRESET, and PULSE GEN needing execution after configuration changes. The manual also covers board-level guidance for fitting options and emphasizes clearing the CMOS RAM after hardware changes. Internal test points can be accessed for diagnostics, and the manual provides guidance on setting display contrast and brightness.
Quick Issues Covered
- Diagnose power-up failures with fuse and voltage checks.
- Identify error codes using the ERROR key for detailed descriptions.
- Circuit tracing via schematics assists in internal test point checks.
Overview
The Rohde & Schwarz SIGNAL GENERATOR SME is a product manufactured using modern methods and developed in compliance with the company’s ISO 9001 certified quality management system. The manual covers various aspects of operating the SME, including preparation for use, setting supply voltage, power fuses, switching the instrument on and off, initial status upon power-on, adjusting display contrast and brightness, and memory functions. It also includes instructions for performing a functional test and fitting options to customize the instrument for specific applications.

Installation / Setup
Before putting the SME signal generator into operation, ensure that the casing covers are secured, ventilation openings are unobstructed, and signal voltage levels at the inputs do not exceed permissible limits. The instrument should not be overloaded or incorrectly connected at the outputs. The SME can operate with an a.c. supply voltage ranging from 90 to 132 V and 180 to 265 V at frequencies from 47 to 440 Hz. It automatically adjusts to the applied voltage within these ranges. The power fuses are located in a draw-out fuse holder between the power supply socket and power switch. The instrument can be switched on or off using the power switch, which is located at the rear, and it can remain switched on permanently unless a complete disconnection from the mains is required. Upon switching on, the instrument can either resume the previous status or have the RF output disconnected. The display’s contrast and brightness can be adjusted using controls below the display. The SME includes a CMOS-RAM with battery back-up for storing settings and calibration data. A lithium battery powers the RAM, and its replacement is detailed in the manual. The instrument performs a self-test upon switching on and continuously during operation. Errors are indicated by an “ERROR” message, which can be further identified using the [ERROR] key. Options can be fitted to the SME, and newly added options are automatically recognized. After changing the configuration, the CMOS RAM must be cleared by switching the instrument on with the [RESET] key pressed, followed by executing internal calibration routines.
Operation
Before operating the SME signal generator, ensure that the casing covers are secured, ventilation openings are unobstructed, and input signal voltage levels are within permissible limits. The SME can operate on AC systems with voltages from 90 to 132 V and 180 to 265 V at frequencies from 47 to 440 Hz, automatically adjusting to the applied voltage. It is protected by two fuses located in a draw-out fuse holder between the power supply socket and power switch.
To switch the instrument on or off, press the power switch. The instrument can remain on permanently, but switching off is necessary to disconnect it from the mains completely. Upon switching on, the instrument either resumes the previous status or disconnects the RF output, depending on the POWER-ON STATE setting. Pressing the [PRESET] key establishes a defined default status.
The SME includes a static RAM with battery backup, capable of storing 50 different settings. A lithium battery powers the RAM, with a service life of approximately five years. The [PRESET] key achieves a defined setting status with specific default parameters for RF frequency, RF level, and other settings.
The SME performs a self-test upon switching on and during operation. Errors are indicated by an “ERROR” message, and further details can be accessed by pressing the [ERROR] key. Options can be fitted to the SME, which are automatically recognized. After changing the configuration, the CMOS RAM must be cleared, and internal calibration routines should be performed to restore calibration values.

Safety & Warnings
Before putting the SME signal generator into operation, ensure that the casing covers are secured, ventilation openings are unobstructed, input signal voltage levels do not exceed permissible limits, and outputs are not overloaded or incorrectly connected. Failure to observe these precautions may result in damage to the instrument. The SME is protected against short circuits by two fuses located in the fuse holder between the power supply socket and power switch.
