Master
Summary/
Service Request
bit The Master Summary Status is used with
the *STB? query. When the *STB? query is
read the MSS bit is not cleared.
The Request Service bit is cleared when it
is polled during a serial poll.
8-22-6. Output Queue
Description The Output queue stores output messages in a FIFO buffer
until read. If the Output Queue has data, the MAV bit in the
Status Byte Register is set.
8-22-7. Error Queue
Description The error queue is queried using the SYSTem:ERRor?
command. The Error queue will set the “Error Queue“ bit in
the status byte register if there are any error messages in the
error queue. If the error queue is full the last message will
generate a “Queue overflow” error and additional errors will
not
be stored. If the error queue is empty, “No error” will be
returned.
Error messages are stored in the error queue in a
first-in-first-out order. The errors messages are character
strings that can contain up to 255 characters.
