Introduction - Status Information and Messages
This chapter describes the error messages of the instrument. The error messages are output in the Info
line on the screen and entered in the error error/event queue of the status reporting system.
A great variety of different messages such as status messages, error messages, warnings or
information are displayed in the header field of the screen. Some error messages require that the error
must be eliminated before correct instrument operation can be ensured.
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.
Error 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).
Brief messages
Brief 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.
Brief messages do not normally demand user actions and disappear automatically after a brief period of
time. They are stored in the history, however.
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 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.
