15 Troubleshooting and notifications
The R&S SMA100B distinguishes between various notifications caused by events or
functions. It displays a notification in the "Info" line on the screen temporarily, and
saves all notifications in a history list. In addition, an event initiates an entry in the
event/error queue of the status reporting system.
See:
●
Chapter 13.4, "Status reporting system", on page 388
●
Chapter 15.4, "Querying notifications", on page 749
15.1 Notifications
Notifications inform about operation states of the instrument, and point out deviations,
deficiencies or imperfection of functions that initiate an event in the instrument. The
instrument distinguishes the notifications according to the significance of the events by
different icons.
Some events require that you eliminate the deviation to make sure that the instrument
operates correctly.
To access the notifications and history list dialog, see Chapter 15.4, "Querying notifica-
tions", on page 749. In remote control mode, you can query the notifications using the
command :SYSTem:ERRor:ALL? on page 715.
15.1.1 Volatile notifications
Volatile notifications report automatic settings in the instrument (e.g. switching off
incompatible types of modulation) or on entries that are not accepted by the instrument
(e.g. range violations).
Volatile notifications do not normally demand user actions and disappear automatically
after a short period of time. They are saved in the history list, however.
Remote command:
:SYSTem:ERRor:ALL? or
:SYSTem:ERRor:CODE[:NEXT]?
15.1.2 Permanent notifications
Permanent notifications are displayed if an error occurs that impairs further instrument
operation, e.g. a hardware fault. The error signaled by a permanent notification must
be eliminated before correct instrument operation can be continued.
