Description
See Section 14 for details on the error queue.
As error and status messages occur, they are placed in the Error Queue. The
Error Queue is a first-in, first-out (FIFO) register that can hold up to 10 mes-
sages. After sending this command and addressing the SourceMeter to talk,
the oldest message is sent to the computer and is then removed from the
queue.
The :STATus:Queue? command performs the same function as
:SYSTem:ERRor[:NEXT]?. See "STATus subsystem."
This query command is similar to the [:NEXT]? command except that all
messages in the Error Queue are sent to the computer when the SourceMe-
ter is addressed to talk. All messages are removed from the queue.
After sending this command and addressing the SourceMeter to talk, a deci-
mal number will be sent to the computer. That is the number of messages in
the Error Queue.
This command is identical to the [:NEXT]? command, except only the code
is returned. The message itself is not returned. The error is cleared from the
queue.
This query command is identical to the :ALL? command, except only the
codes are returned. The actual messages are not returned. All errors are
cleared from the queue.
This action command is used to clear the Error Queue of messages.
