Configuration Commands
The following subsystems contain the commands for channel selection, voltage and
current settings for the instrument.
7.3.1
Channel Selecting
The
INSTrument:Select
subsystem contains the commands for selecting the output
channels.
Each channel of the power supply is considered as separate "instrument", which is
required by the SCPI standard. Therefore, the SCPI commands use the
INSTRument
node to select a channel.
You can only address the number of channels a device is equipped with, e.g. a maxi-
mum of two channels for the NGA102 and NGA142.
Example: Selecting a channel
You can select a channel either with an
OUTput
parameter, or just by the channel
number. This example lists all ways how you can select and query a selected channel.
// ************************************************

// ************************************************
// Select a channel by its number
// ************************************************

INST:NSEL 1
// queries number of the channel selection
INST:NSEL?
// response: 1
