8-110. Summary of Commands and Queries
This section describes commands and queries that are used specifically for the
oscilloscope calibration option. Each command description indicates whether it can be
used with IEEE-488 and RS-232 remote interfaces and identifies it as a Sequential,
Overlapped, or Coupled command.
IEEE-488 (GPIB) and RS-232 Applicability
IEEE-488 RS-232
xx
Each
command and query have a check box indicating applicability to IEEE-488 (general
purpose interface bus, or GPIB) and RS-232 remote operations.
Sequential Commands
Sequential
x
Commands executed immediately as they are
encountered in the data stream are called sequential commands. For more information,
see “Sequential Commands” in Chapter 5.
Overlapped Commands
Overlapped
x
Commands SCOPE, TRIG, and OUT_IMP
are designated as overlapped commands because they may be overlapped (interrupted)
by the next command before they have completed execution. When an overlapped
command is interrupted, it may take longer to execute while it waits for other commands
to be completed. To prevent an overlapped command from being interrupted during
execution, use *OPC, *OPC?, or *WAI. These commands prevent interruptions until
they detect the command’s completion. For more information, see “Overlapped
Commands” in Chapter 5.
Coupled Commands
Coupled
x
SCOPE and OUT_IMP are coupled commands
because they can be coupled (combined) with other commands to form a compound
command sequence. Care must be taken to ensure that commands are not coupled in a
way that may cause them to disable each other, since this may result in a fault. For more
information, see “Coupled Commands” in Chapter 5.
