4.4 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 that most commands are the mixture of capital and lower case letters. The capital 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 capital 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 capital or lower case letters for the commands, CURR, Curr, and CURr are all acceptable. Notice that the
capital 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
4.5 Command Separators
A colon “ ：” is used to separate a command keyword from a lower-level keyword as shown below:
SOURce:CURRent:TRIGgered
A semicolon “ ；” is used to separate two commands within the same subsystem as shown below:
SOUR:VOLT MIN;CURR MAX
The following two commands have the same effect as the above command.
SOUR:VOLT MIN
SOUR:CURR MAX
Use a colon and a semicolon to link commands from different subsystems.
For example, in the following command string, an error is generated if you do not use the colon and semicolon:
MEAS:VOLT?;:SOUR:CURR MIN
