Synchronizing the Analyzer and a
Controller
The IEEE 488.2 standard provides tools that can be used to synchronize
the analyzer and a controller. Proper use of these tools ensures that the
analyzer is in a known state when you send a particular command or
query.
Device commands can be divided into two broad classes:
• Sequential commands
• Overlapped commands
Most of the analyzer's commands are processed sequentially. A
sequential command holds off the processing of subsequent commands
until it has been completely processed.
Some commands do not hold off the processing of subsequent commands;
they are called overlapped commands.
