Status Information and Messages - Display
The status information and messages are displayed in the header section of the screen. The messages
differ with respect to their importance (errors, warnings, info) and the time of their appearance (brief and
permanent messages). They require different treatment by the user. Further information on all
messages can be called in the info window (see section "Info Window - Display", page 3.6).
Chapter 9, "Error Messages" includes an overview of all status information and messages as well as
instructions for error elimination.
Status Information
The status information gives the user an overview of the main operating states and settings of the
R&S SMB. The states are indicated for information only and do not necessitate any action by the user.
Status information is displayed between the frequency and level fields, at the left of the info line or in the
info line itself.
Messages
Messages indicate errors in the instrument. They are displayed in the info line 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).
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 background. 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.
Remote-control command:
SYST:ERR? or SYST:ERR:ALL?
Permanent messages
Permanent messages are displayed if an error occurs that impairs further instrument operation, e.g. a
hardware fault. The error signalled by a permanent message must be eliminated before correct
instrument operation can be ensured.
The message is displayed until the error is eliminated. It covers the status display in the info line. After
error elimination, the message automatically disappears and is also recorded in the history.
Remote-control command:
SYST:SERR?
