Sequential Commands; Commands For Rs-232 Only; Commands For Ieee-488 Only - Fluke 525B User Manual

You can use the command *WAI to wait until the overlapped command has
completed execution before executing the next command. For example,
OUT 1 V ; *WAI
You can also use the status commands *OPC and *OPC? to detect completion of
overlapped commands. (See "Checking 525B Status.")

Sequential Commands

Commands that execute immediately are called sequential commands.
In Chapter 5, the command graphic
commands.
The majority of the commands are sequential.

Commands for RS-232 Only

The command graphic
commands.
The IEEE-488 and RS-232 interfaces both send commands to the Calibrator as
data, except for those IEEE-488 functions that must be implemented as a message
as specified in the IEEE-488 standards. For example, the RS-232 interface uses the
command REMOTE to place the Calibrator in the Remote mode. Although the
IEEE-488 interface could also send a command REMOTE as data, it does not
because this is one of the functions that must be implemented per IEEE-488
Standards. The relationship between these IEEE-488 messages and the equivalent
RS-232 emulation is shown in Table 4-7.

Commands for IEEE-488 Only

IEEE-488 interface. This is all the commands, except for those used for RS-232
operations. (See "Commands for RS-232 Only.") All commands are transferred
over the IEEE-488 as data, except for the commands LOCAL, REMOTE, and
LOCKOUT, which are implemented per IEEE Standards as messages.
