6.5.8 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 of *RST and
SYSTem:PRESet affect the functional instrument settings. In particular, DCL does not
change the instrument settings.

1) The first command in a command line that immediately follows a <PROGRAM MESSAGE TERMINA-
TOR> clears the output buffer.

6.6 General Programming Recommendations

Initial instrument status before changing settings
Manual operation is designed for maximum possible operating convenience. In con-
trast, 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. Therefore, control programs should always define an initial instrument status
(e.g. using the *RST command) and then implement the required settings.
Command sequence
As a general rule, send commands and queries in different program messages. Other-
wise, the result of the query may vary depending on which operation is performed first
(see also Preventing Overlapping Execution).
