User Manual 1317.4726.02 ─ 01
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. Especially
in the test phase of a controller program the error queue should be queried regularly since
faulty commands from the controller to the instrument are recorded there as well.
15.1.6.5
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.

15.1.7 General Programming Recommendations
Initial instrument status before changing settings
Manual operation is designed for maximum possible operating convenience. In contrast,
the priority of remote control is the "predictability" of the instrument status. Thus, when a
command attempts to define incompatible settings, the command is ignored and the
instrument status remains unchanged, i.e. other settings are not automatically adapted.
