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 74 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” selects +6V output, “2” selects +25V 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.
