Refer to "Error messages" in the Operating Manual for an overview of all status infor-
mation and messages and corrective actions.
Status Information
The status information gives the user an overview of the main operating states and set-
tings of the instrument. The states are indicated for information only and do not neces-
sitate 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 differ-
ent colors depending on their importance and display duration. Errors (e.g. no calibra-
tion 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
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?
.
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.
These messages can be read from remote using
SYST:ERRor:STATic?
.
