successful Some applications visualize that the measurement was successful by show-
ing a message.
If any error information is available for a channel, an exclamation mark is displayed
next to the channel name ( ). This is particularly useful when the MultiView tab is dis-
played, as the status bar in the MultiView tab always displays the information for the
currently selected measurement only.
Furthermore, a status bit is set in the
STATus:QUEStionable:EXTended:INFO
reg-
ister for the application concerned (see "STATus:QUEStionable:EXTended:INFO Reg-
ister" on page 761). Messages of a specific type can be queried using the
SYST:ERR:EXT?
command, see
SYSTem:ERRor:EXTended?
on page 1304.
