12.3.7 Abbreviation of Compound Commands
For the integer values as a parameter of the following commands, the
decimal fractions are rounded, but for the ":CURRent [channel]:RANGe"
command for current range setting in range 0.2A and 0.5 A, the second
decimal place is rounded.
The real numbers as a parameter of the following commands are rounded to
the fifth decimal place.
:SCALe[ch]:CT
:SCALe[ch]:PT
:SCALe[ch]:SC
:EXTernalin[CH]:SCALe
The following commands are set to 150 V range.
":VOLTage1:RANGe 150"
":VOLTage1:RANGe 150.2"
":VOLTage1:RANGe 1.495E2"
For the response data, the format is specified for each commands and the
data in specified format is transmitted.
When several compound commands have a common head portion, for
example :SCAL1:PT and :SCAL1:CT, then, when and only when writing
them directly following on from one another, this common portion (:SCAL1:
in this example) can be omitted from each command. This common portion
is called "the current path", by analogy with the general concept of the
current directory in the directory structure of UNIX or MS-DOS, and until it
is cleared the analysis of following commands is performed by deeming
them to be preceded by the current path which has been curtailed in the
interests of brevity. This manner of using the current path is shown in the
following example:
Normal expression
":SCALe1:CT 5;:SCALe1:PT 10;:SCALe1:SC 100"
Abbreviated expression:
" :SCALe1: CT 5;PT 10;SC 100"
This becomes the current path, and can be curtailed
from the following commands.
The current path is cleared when the power is turned on, when a system
reset is performed by key input, when a colon ":" appears at the start of a
command, and when a message terminator is detected.
Messages of standard command form can be executed without relation to the
current path. Further, they have no effect upon the current path.
It is not necessary to prefix a colon ":" at the start of headers of simple
commands and compound commands. However, in order to prevent
confusion with abbreviated forms and mistakes in operation, it is
recommended practice always to prefix ":" to headers.
