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.
