Command Format Used in This Manual
The format used to show commands in this manual is shown below:
CURRent {
<
current
>
|MINimum|MAXimum}
The command syntax shows most commands are the mixture of upper- and
lower-case letters. The upper-case letters indicate the abbreviated spelling for the
command. For shorter program lines, send the abbreviated form. For better program
readability, send the long form. But notice that only the complete spelling form and
the upper-case letters are acceptable for the keyword. Give the following example to
illustrate:
In the above syntax statement, CURR and CURRENT are both acceptable forms for
the keyword “CURRent”. As you can use the mixture of upper- or lower-case letters
for the commands, CURR, Curr, and CURr are all acceptable. Notice that the
upper-case letters are indispensable. For example, “CUR” is incorrect. And “CURRe”,
“CURRen”, will generate an error because of the incomplete spelling.
Braces “{ }” enclose the parameter choices for a given command string. The braces
are not sent with the command string.
A vertical bar “|” separates multiple parameter choices for a given command string.
Triangle brackets “< >” indicate that you must specify a value for the enclosed
parameter. For example, the above syntax statement shows the current parameter
enclosed in triangle brackets. You must specify a value for the current parameter,
which is not enclosed in the triangle bracket (such as “CURR 0.1”)..
Some parameters are enclosed in square brackets “[ ]”. The brackets indicate that the
parameter is optional and can be omitted. The brackets are not sent with the command
string. If you do not specify a value for an optional parameter, a default value will be
chosen by power supply.
A colon “:” separates a command keyword from a lower-level keyword. You must
insert a blank space to separate a parameter from a command keyword. If a command
requires more than one parameter, you must separate adjacent parameters with a
comma as shown below:
SOURce:CURRent:TRIGgered
APPL 3.5,1.5
