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 (and some parameters) as a
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.
For example, in the above syntax statement,
CURR
and
CURRENT
are both
acceptable forms. You can use upper- or lower-case letters. Therefore,
CURRENT
,
curr
, and
Curr
are all acceptable. Other forms, such as
CUR
and
CURREN
, will generate an error.
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. The brackets are not sent
with the command string. You must specify a value for the parameter (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, the power supply chooses a default value.
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 using a
comma as shown below:
"SOURce:CURRent:TRIGgered"
"APPL P6V,3.5,1.5"
