The service manual for the Rohde & Schwarz SWOB5-Z5 details the setup and operation of the overvoltage protection device, which is connected between the RF output of the Polyskop SWOB 5 and the test item to prevent damage from overvoltages. It also provides troubleshooting guidance, including checking and adjusting the response threshold, and outlines the necessary maintenance to ensure the device functions correctly.
Manual Overview
The Rohde & Schwarz SWOB5-Z5 Overvoltage Protection manual provides detailed instructions for troubleshooting, diagnostics, and maintenance of the device. The overvoltage protection is designed to prevent damage to the Polyskop SWOB 5 by disconnecting the RF output from the test object when overvoltages occur. This is achieved through a coaxial relay that operates with a response threshold of approximately ±4 V for DC and 4 V for RF voltage, with a relay disconnect time of 3 ms. The device requires no special maintenance, but periodic checks are recommended to ensure specifications are met.
For troubleshooting, the manual suggests using the functional description to isolate faults. Adjustments, such as recalibrating the response threshold, can be made using resistor R10. The device’s power is supplied through a connection to the Polyskop SWOB 5, utilizing stabilizer circuits to derive the necessary voltages. Repair instructions include using measuring equipment specified in the Polyskop SWOB 5 manual. The manual emphasizes the importance of maintaining clean switching edges and preventing continuous relay switching through specific circuit designs.
Quick Issues Covered
- Diagnose overvoltage issues via comparator threshold adjustments.
- Check and adjust response threshold with potentiometer R10.
- Use schematics for circuit tracing and fault isolation.
