Using the APPLy Command
The
APPLy
command provides the most straightforward method to program
the power supply over the remote interface. You can select the specific
output, output voltage, and output current all in one command.
APPLy
{P6V | P25V | N25V}[,{<
voltage
>| DEF | MIN | MAX}[,{<
current
>| DEF | MIN | MAX}]]
This command is combination of
INSTrument:SELect
, [
SOURce:
]
VOLTage
, and
[SOURce:]CURRent
commands. The values of voltage and
the current of the specified output are changed as soon as the command is
executed.
You can identify each output by the output name (P6V, P25V or N25V) as
described in Table 4-1. For the
voltage and current parameters of the
APPLy
command, the ranges depend on the output currently selected. You can
substitute “MINimum”, “MAXimum”, or “DEFault” in place of a specific
value for the
voltage and current parameters. MIN selects the lowest voltage
and current values allowed for the selected output. MAX selects the highest
voltage and current values allowed. The
default voltage values are 0 volts
for all outputs. The default current values are 5 A for +6V output and 1 A for
±25V outputs. The default voltage and current values are exactly the same as
the
*RST
values. See Table 4-1 for details of parameters.
If you specify only one value for the parameter, the power supply regards it
as voltage setting value. If you do not specify any value for the parameter,
the
APPLy
command only selects the output specified and acts as the
INSTrument
command.
APPLy? [{P6V | P25V | N25V}]
This command queries the power supply's present voltage and current
values for each output and returns a quoted string. The voltage and current
are returned in sequence as shown in the sample string below (the quotation
marks are returned as part of the string). If any output identifier is not
specified, the voltage and the current of the currently selected output are
returned.
"5.000000,1.000000"
In the above string, the first number 5.000000 is the voltage limit value and
the second number 1.000000 is the current limit value for the specified
output.
