Troubleshooting

 

The 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). 
 

NOTE 

Do not insert or remove boards that are still  live 

Avoid causing shorts when measuring voltages

 

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.
