14 Troubleshooting and Error Messages
The R&S
SMA100B distinguishes between various different messages such as status
messages, error messages, warnings, or information that are displayed in the "Info"
line on the screen, and also entered in the error/event queue of the status reporting
system.
This section describes the types of error messages and warnings. The status reporting
system is described in detail in
Chapter A.1.5, "Status Reporting System"
You can also access an Info window with detailed information about all messages in a
history list. For details, see
Chapter 14.4, "Querying Error Messages & Info Key"
14.1 Error Messages
Error messages indicate errors in the instrument. They are displayed in different colors
depending on their importance and display duration. Errors (e.g. no calibration data)
are displayed in red, information (e.g. file not found) and warnings in black. Warnings
indicate less significant errors (e.g. the instrument operates outside specified data).
Some error messages require that the error must be eliminated before correct instru-
ment operation can be ensured. To access the "Info" dialog with a list of current mes-
sages and a detailed description of each message, select "Info".
In the remote control mode, error messages are entered in the error/event queue of the
status reporting system and can be queried with the command
SYSTem:ERRor?
. If the
error queue is empty, 0 ("No error") is returned.
14.1.1 Volatile Messages
Volatile messages report automatic settings in the instrument (e.g. switching off of
incompatible types of modulation) or on illegal entries that are not accepted by the
instrument (e.g. range violations). They are displayed in the info line on a yellow back-
ground. They are displayed on top of status information or permanent messages.
Volatile messages do not normally demand user actions and disappear automatically
after a brief period of time. They are stored in the history, however.
14.1.2 Permanent Messages
Permanent messages are displayed if an error occurs that impairs further instrument
operation, e.g. a hardware fault. The error signaled by a permanent message must be
eliminated before correct instrument operation can be continued.
