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,
and can also minimize typing. For example, sending the following command
string:
‘‘
SOUR:VOLT MIN;CURR MAX
’’
... is the same as sending the following two commands:
‘‘
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:
‘‘
DISP:TEXT:CLE;:SOUR:CURR MIN
’’
Using the MIN and MAX Parameters
You can substitute
MINimum
or
MAXimum
in place of a parameter for many
commands. For example, consider the following command:
CURRent {<current>|MIN|MAX}
Instead of selecting a specific current, you can substitute
MINimum
to set the
current to its minimum value or
MAXimum
to set the current to its maximum
value.
