Operation
The RC-Generator SRB provides sinusoidal voltages with adjustable amplitude and frequency ranging from 10 Hz to 1 MHz. It features switchable source resistance for common connection values between 50 and 600 ohms. Key characteristics include high frequency stability, low distortion factor, and frequency response, along with high output power and accurate voltage indication. The device is suitable for measurements in acoustics, ultrasound, low-frequency, and high-frequency technology. The Symmetrierübertrager for the SRB is used for feeding symmetrical line systems and amplifiers that require a push-pull voltage or ground-free input voltage. It can also be used to interrupt network hum loops. The device has a low internal resistance, providing nearly the full transformed EMF of the generator as output voltage with a secondary load of 600 ohms. A slight asymmetry occurs near the upper frequency limit. The Symmetrierübertrager is well-suited for transmitting a stereo multiplex signal.

Basic Usage and Operation Tips
Before powering on the SRB RC Generator, ensure all connections are secure and the device is properly grounded. Use the front panel controls or remote interface to select the desired frequency and output power. For modulation, choose the appropriate mode and configure parameters according to your test requirements. Always allow the device a warm-up period of at least 15 minutes to achieve optimal frequency stability. Regularly calibrate the generator using certified standards to maintain accuracy.
Troubleshooting and Maintenance
If the output signal is unstable or deviates from expected parameters, verify cable integrity and connection quality. Reset the device to factory settings if configuration errors occur. Clean the exterior with a soft, dry cloth and avoid using solvents. Schedule periodic calibration checks and firmware updates as recommended by Rohde-Schwarz to ensure peak performance. In case of persistent faults, consult the technical support service or authorized repair centers.
