5-31. Overlapped Commands

Commands that begin execution but require slightly more time to complete are called
overlapped commands, because they can be overlapped by the next command before
they have completed execution.
In Chapter 6, the command graphic shows a check mark for
The 25 overlapped commands are:
BOOST
CUR_POST
DC_OFFSET
DPF
DUTY
EARTH
HARMONIC
INCR
LOWS
MULT
OPER
OUT
OUT_IMP
PHASE
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, 1 A, 60 HZ ; *WAI
You can also use the status commands *OPC and *OPC? to detect completion of
overlapped commands. (See "Checking 5500A Status.")

5-32. Sequential Commands

Commands that execute immediately are called sequential commands.
In Chapter 6, the command graphic shows a check mark for
The majority of the commands, 87 of 111 commands, are sequential.

5-33. Commands that Require the Calibration Switch to be Enabled

The following commands do not work unless the rear panel CALIBRATION switch is in
the ENABLE position:
FORMAT ALL
FORMAT CAL
*PUD
Attempting to use any of these commands with the CALIBRATION switch in the
NORMAL position logs an error into the error queue. (Or it returns the error message if
in the RS-232 Terminal Mode.)

5-34. Commands for RS-232 Only

Commands that are used for the RS-232 interface only are identified in the command
graphic by checking the
