Safety & Warnings
This unit has been designed and tested according to the standards outlined overleaf and has left the manufacturer’s premises in a state fully complying with the safety standards. In order to maintain this state and to ensure safe operation, observe the following instructions, symbols and precautions.
1) When the unit is to be permanently cabled, first connect protective ground conductor before making any other connections.
2) Built-in units should only be operated when properly fitted into the system.
3) For permanently cabled units without built-in fuses, automatic switches or similar protective facilities, the AC supply line shall be fitted with fuses rated to the units.
4) Before switching on the unit ensure that the operating voltage set at the unit matches the line voltage. If a different operating voltage is to be set, use a fuse with appropriate rating.
5) Units of protection class I with disconnectible AC supply cable and plug may only be operated from a power socket with protective ground contact. The protective ground connection should not be made ineffective by an extension cable. Any breaking of the protective ground conductor within or outside of the unit or loosening of the protective ground connection may cause the unit to become electrically hazardous. The protective ground conductor shall not be interrupted intentionally.
6) Before opening the unit, isolate it from the AC supply. Adjustment and replacement of parts as well as maintenance and repair should be carried out only by specialists approved by R&S. Observe safety regulations and rules for the prevention of accidents. Use only original parts for replacing parts relevant to safety (e.g. power on/off switches, power transformers or fuses).
7) Also observe the additional safety instructions specified in this manual.

- High spectral purity with low phase noise
- Amplitude range: -130 dBm to +13 dBm
- Modulation capabilities including AM, FM, PM, and pulse modulation
- Built-in frequency counter and marker functions
- Intuitive user interface with a graphical display
- Remote control via GPIB and RS-232 interfaces
- Compact and robust design for laboratory and field use
Basic Usage and Operation Tips
Before operating the signal generator, ensure it is properly connected to a stable power source and the output is connected to the device under test. Use the front panel controls or remote interface to select the desired frequency and modulation settings. Always start with low output power and gradually increase to avoid damaging connected equipment. Regularly calibrate the device according to the manufacturer’s schedule to maintain accuracy.
Troubleshooting and Maintenance
If the signal generator fails to produce output or exhibits abnormal behavior, first verify all cable connections and power supply status. Check for any error messages displayed on the screen and consult the manual for specific error codes. Routine maintenance includes cleaning the exterior surfaces, inspecting connectors for damage, and performing periodic calibration. Avoid opening the device unless qualified, as internal components are sensitive and require specialized handling.
Safety Reminder
Always follow proper safety precautions when operating the signal generator. Avoid exposure to high RF output levels to prevent potential health hazards. Ensure the device is properly grounded and use only recommended accessories. Disconnect power before performing any maintenance or internal inspections to reduce the risk of electric shock.
