essages 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?
Info Window - Display
A few operating states and the current message are displayed in the info line (see also chapter 9, "Error
Messages").
The info window with a list of current permanent messages and a detailed description of each message
can be opened with the
INFO key.
The upper section of the info window contains a list of all current permanent messages in the order of
their occurrence, i.e. the most recent message is displayed first. In the lower section of the window,
additional information on the highlighted message is displayed.
