Handling R&S SMB100B start-up issues
If the product does not start, a blown fuse in the power supply can be the cause. Con-
tact the Rohde & Schwarz customer service to confirm the fault symptoms. If the power
supply has a blown fuse, you must return the product to the Rohde & Schwarz cus-
tomer service to have the power supply replaced. Follow the instructions from the
Rohde & Schwarz customer service.
If you need to transport or ship the instrument, see Chapter 14, "Transporting",
on page 586.
Understanding R&S SMB100B notifications
The R&S SMB100B 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 11.4, "Status reporting system", on page 276
●
Chapter 13.4, "Querying notifications", on page 576
13.1 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 13.4, "Querying notifica-
tions", on page 576. In remote control mode, you can query the notifications using the
command :SYSTem:ERRor:ALL? on page 521.
13.1.1 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.
