The reference oscillator has not yet reached its nominal frequency.
When switching on from the STANDBY mode, the specified frequency accuracy is
reached immediately. If the power switch was switched off, the reference oscillator needs
some warm-up time to reach its nominal frequency. During this period of time, the output
frequency does not yet reach its final value either.
9.2 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. Warn-
ings indicate less significant errors (e.g. the instrument operates outside specified data).
9.2.1 Volatile messages
Volatile 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.
9.2.2 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 recor-
ded in the history.
9.3 SCPI-Error Messages
The SCPI error messages are the same in all SCPI instruments. Detailed information and
an overview of all error messages as defined in SCPI standard can be found in the cor-
responding documentation.
