R&S SMB Function Check
1407.0812.62 1.17 E-2
Function Check
The signal generator automatically monitors the main functions when the instrument is switched on and
continuously during operation.
If a fault is detected, ERROR is displayed in the info line together with a brief error description.
For in-depth identification of the error, press the
INFO key. In response, a description of the error(s) is
displayed (see Chapter 9, "Error Messages").
Besides automatic monitoring of instrument functions, other capabilities in the R&S SMB ensure correct
functioning of the signal generator.
