If you get firmware errors even with the properly installed latest software version,
please send a problem report including log files to Rohde & Schwarz.
●
102 (Unidentified Error)
:
Indicates an error not covered by other reliability values. For troubleshooting
please follow the steps described for "101 (Firmware Error)".
●
103 (Parameter Error)
:
Indicates that the measurement could not be performed due to internal conflicting
parameter settings.
A good approach to localize the conflicting settings is to start with a reset or preset
or even restore the factory default settings. Then reconfigure the measurement
step by step and check when the error occurs for the first time.
If you need assistance to localize the conflicting parameter settings, please contact
