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 output voltage and current
in one command.
APPLy {<voltage>| DEF | MIN | MAX}[,{<current>| DEF | MIN | MAX}]
This command is combination of VOLTage and CURRent commands. As long as
the newly programmed values are within the presently selected range, the output
voltage and current are changed as soon as the command is executed.
The APPLy command changes the power supply’s output to the newly programmed
values only if the programmed values are valid within the presently selected range.
An execution error will occur if the programmed values are not valid within the
selected range.
You can substitute ‘‘MINimum’’, ‘‘MAXimum’’, or ‘‘DEFault’’ in place of a
specific value for the voltage and current parameters. MIN selects the lowest values
of ‘‘0’’ volts and ‘‘0’’ amps. MAX selects the highest values allowed for the selected
range.
The default values of voltage and current are ‘‘0’’ volts and ‘‘20’’* or ‘‘7’’** amps
regardless of the presently selected range. For more details of parameters, see Table
4-1 for the Agilent E3633A model and Table 4-2 for the Agilent E3634A model.
If you specify only one parameter of the APPLy command, the power supply regards
it as voltage setting value.
APPLy?
This command queries the power supply’s present voltage and current setting values
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).
‘‘8.00000,20.00000’’* or ‘‘25.00000,7.00000’’**
In the above string, the first number 8.00000 is the voltage setting value and the second
number 20.00000 is the current setting value.
