Syntax rules for instrument commands
Syntax rule
Details
Examples
Case sensitivity:
Instrument
commands are case
sensitive.
Match the case
shown in the
command reference
descriptions.
Function and attribute
names should be in
lowercase characters.
An example of the
scriptVar.save()
function (where
test8
is the name of the script):
test8.save()
Parameters can use a
combination of
lowercase and
uppercase characters.
Attribute constants use
uppercase characters
In the command below, which sets the format of data
transmitted from the instrument to double-precision floating
point,
format.REAL64
is the attribute constant and
format.data
is the attribute command:
format.data = format.REAL64
White space:
Not
required in a function.
Functions can be sent
with or without white
spaces.
The following functions, which set digital I/O line 3 low, are
equivalent:
digio.writebit(3,0)
digio.writebit (3, 0)
Function
parameters:
All
functions are required
to have a set of
parentheses ()
immediately following
the function.
You can specify the
function parameters by
placing them between
the parentheses. Note
that the parentheses
are required even when
there are no parameters
specified.
The following function specifies all overlapped commands in
the nodes in group G that must complete before commands
from other groups can execute:
waitcomplete(G)
The command below reads the value of the local time zone
(no parameters are needed):
timezone = gettimezone()
Multiple parameters:
Must be separated by
commas (,).
Some commands
require multiple
parameters, which must
be separated by
commas (
,
).
This command sets the beeper to emit a double-beep at
2400 Hz, with a beep sequence of 0.5 seconds on, 0.25
seconds off, and then 0.5 seconds on:
beeper.beep(0.5, 2400)
delay(0.250)
beeper.beep(0.5, 2400)
Parameter range:
Range values must
be separated with a
colon (:).
Place a colon (:)
between two values to
specify a range in a
parameter.
The command below replaces the active scan list with an
empty scan list, and then adds channels in row 1, columns 1
through 10, on slot 1:
scan.create("1A01:1A10")
