Output Setting and Operation Commands
This section describes the low-level commands used to program the power
supply. Although the
APPLy
command provides the most straightforward
method to program the power supply, the low-level commands give you
more flexibility to change individual parameters.
See page 102 for programming ranges, output identifiers, and MIN / MAX
values in the following commands.
Output Selection Commands
INSTrument[:SELect] {P6V | P25V | N25V}
This command selects the output to be programmed among three outputs by
the output identifier. The outputs of the power supply are considered three
logical instruments. The
INSTrument
command provides a mechanism to
identify and select an output. When one output is selected, the other outputs
are unavailable for programming until selected. The commands which are
affected by the
INSTrument
command are output setting commands
(
SOURce
), measurement commands (
MEASure
), and calibration commands
(
CALibration
). “P6V” is the identifier for +6V output, “P25V” is for +25V
output and “N25V” is for -25V output.
INSTrument[:SELect]?
This query returns the currently selected output by the
INSTrument
[
:SELect
] or
INSTrument:NSELect
command. The returned
parameter is “P6V”, “P25V”, or “N25V”.
INSTrument:NSELect {1 | 2 | 3}
This command selects the output to be programmed among three outputs by
a
numeric value instead of the output identifier used in the
INSTrument
[
:SELect
] command. “1” s6V output, “2” s25V output, and
“3” selects -25V output.
INSTrument:NSELect?
This query returns the currently selected output by the
INSTrument
:NSELect
or
INSTrument
[
:SELect
] command. The returned parameter
is “1” for +6V output, “2” for +25V output or “3” for -25V output.
