Querying Parameter Settings
You can query the value of most parameters by adding a question mark (?) to the
command. For example, the following command sets the output current to 5A
CURR 5
You can query the value by executing:
CURR?
You can also query the minimum or maximum value allowed with the present
function as follows:
CURR? MAX
CURR? MIN
SCPI Command Terminators
A command string sent to the power supply must terminate with a <new line>
character. The IEEE-488 EOI (end-or-identify) message is interpreted as a <new line>
character and can be used to terminate a command string in place of a <new line>
character. A <carriage return> followed by a <new line> is also accepted.
SCPI Parameter Types
The SCPI language defines several different data formats to be used in program
messages and response messages.
Numeric Parameters: Commands that require numeric parameters will accept all
commonly used decimal representations of numbers including optional signs, decimal
points, and scientific notation. Special values for numeric parameters like MINimum,
MAXimum, and DEFault are also accepted. You can also send engineering unit
suffixes (V, A or SEC) with numeric parameters. If only specific numeric values are
accepted, the power supply will automatically round the input numeric parameters.
The following command uses a numeric parameter:
CURR {<current
>
|MINimum|MAXimum}
Discrete Parameters: Discrete parameters are used to program settings that have a
limited number of values (like BUS, IMM). Query responses will always return the
