data) are displayed in red, information (e.g. file not found) and warnings in black. Warn-
ings indicate less significant errors (e.g. the instrument operates outside specified data).
4.2.2.3 Volatile messages
Brief messages report automatic settings in the instrument (e.g. switching off of incom-
patible 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.
These messages can be read from remote using SYST:ERR? or SYST:ERR:ALL?.
4.2.2.4 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 recor-
ded in the history.
These messages can be read from remote using SYST:SERR?.
4.2.3 Info Window
A few operating states and the current message are displayed in the info line.
The INFO window with a list of current permanent messages and a detailed description
of each message can be opened with the INFO (CTRL+I) 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 dis-
played. A history of all messages that have occurred since instrument switch-on can be
called with the "History" key. The most recent message is displayed first.
