Example:
The decimal value 40 = 32 + 8 indicates that bits no. 3 and 5 in the status register (e.g.
the QUEStionable status summary bit and the ESB bit in the STatus byte) are set.
16.5.4 Error queue
Each error state in the instrument leads to an entry in the error queue.
The error queue should be queried after every SRQ in the controller program as the
entries describe the cause of an error more precisely than the status registers. Espe-
cially in the test phase of a controller program the error queue should be queried regu-
larly since faulty commands from the controller to the instrument are recorded there as
well.
16.5.5 Reset values of the status reporting system
The following table contains the different commands and events causing the status
reporting system to be reset. None of the commands, except *RST and
SYSTem:PRESet, influence the functional instrument settings. In particular, DCL does
not change the instrument settings.
