TYPE

EXECUTION
Immediate
SYNTAX
X
Execute preceding command string.
DESCRIPTION
Deferred commands are interpreted and processed in the Acquisition Buffer as they are received, but they
require the Execute (X) command to be issued in order to be executed. If multiple system commands are used
in the same string, each use of the command must be followed by the Execute (X) command. Any number of
Execute (X) commands may be inserted into the same command string. However, immediate commands do not
require an Execute (X) command to be processed.
While a command line is being interpreted, the front panel LED indicators will not be updated. These LED
indicators will only be updated when the unit is in a ready state. In order to determine if the unit is in a ready
state, perform a Serial Poll on the Status Byte Register (
STB
) for the Ready Bit (Bit 3).
For more detail on deferred and immediate command types, see section Command Interpretation at the
beginning of this chapter.
