Troubleshooting
T
he instructions in this manual describe troubleshooting down to the board level. Any defective boards
can then be replaced and the instrument put back into operation. A selftest which checks the board
diagnostic voltages and displays limit violations is provided to facilitate troubleshooting and diagnosis.
We recommend that you return your instrument to the technical specialists at an R&S service facility for
board replacement and any further repairs that may be needed (see the address list at the beginning of
this manual).
WARNING
Do not insert or remove boards that are still live
Avoid causing shorts when measuring voltages
The R&S ZVB has the following facilities to simplify diagnosis:
• Selftest
• Service functions
N.B. The first thing to do if you encounter any problems is to check if any connection (cables,
edge connectors etc.) are damaged or even incorrectly inserted.
