The operation manual for the Rohde & Schwarz SMT Signal Generator provides detailed instructions on setting up and operating the device using remote control via IEC-bus and RS-232 interfaces, including command syntax, error handling, and status register configuration. It also includes troubleshooting guidance, such as returning to manual control and changing device addresses, with program examples for IEC-bus programming in Quick BASIC.
Manual Overview
Chapter 3 of the Rohde & Schwarz SMT Signal Generator Operation Manual focuses on remote control capabilities, detailing the use of IEC-bus and RS-232 interfaces for controlling the instrument. The manual emphasizes the importance of understanding IEC-bus programming and SCPI standards for effective remote operation. It provides a step-by-step guide for setting up remote control via both interfaces, including the necessary commands to initialize and configure the device. The chapter explains how to switch between manual and remote control modes, highlighting that remote control disables front panel operations until switched back manually or via command. The manual outlines the procedure for setting the device address on the IEC-bus and configuring RS-232 transmission parameters to ensure error-free communication. It also describes the status indicators that show whether the device is in remote or local mode. Troubleshooting guidance includes ensuring command processing completion before switching modes and using specific commands to prevent unintentional mode changes.
Quick Issues Covered
- Diagnose remote control issues via IEC-bus or RS-232 interface.
- Resolve power-up failures by resetting instrument with *RST command.
- Adjust IEC-bus address manually or via command for connectivity.

Operation
The manual provides instructions for operating the instrument via remote control using either the IEC-bus or RS-232 interface. For IEC-bus operation, the instrument’s factory-set address is 28, and users must connect the instrument and controller with an IEC-bus cable. A program is written on the controller to open the port, reset the instrument, set frequency and output levels, and configure amplitude modulation. To switch back to manual control, the LOCAL key on the front panel is pressed.
For RS-232 interface operation, a 0-modem cable connects the unit and controller. The controller interface is configured with specific parameters, and an ASCII file with commands is created and transferred to the unit. The process also involves setting frequency, output levels, and modulation. Returning to manual control is done by pressing the LOCAL key.
The instrument starts in manual mode upon power-on and switches to remote control upon receiving specific commands. During remote control, front panel operation is disabled, and the instrument remains in remote mode until reset manually or via the IEC bus. The IEC-bus address can be changed manually or via the bus, and the remote control state is indicated on the STATUS page.

Basic Usage and Operation Tips
Before powering on the device, ensure all cables and connectors are securely attached. Use the front panel controls or remote software interface to select the desired frequency and modulation type. Always start with low output power settings and gradually increase to the required level to avoid damaging connected equipment. Regularly calibrate the signal generator according to the manufacturer's guidelines to maintain accuracy.
Troubleshooting and Maintenance
If the device fails to power on, verify the power supply and fuse condition. In case of signal distortion or unexpected output, check all cable connections and ensure the device firmware is up to date. Clean the exterior with a soft, dry cloth and avoid using harsh chemicals. Schedule periodic professional calibration and servicing to ensure long-term reliability.
Safety Reminder
Always operate the signal generator in a dry, well-ventilated environment. Avoid exposure to extreme temperatures and moisture. Do not open the device casing; servicing should only be performed by qualified personnel to prevent electric shock or damage. Follow all local regulations and manufacturer safety instructions when using the equipment.
