7.5 Configuration Commands

The following subsystems contain the commands for channel selection, voltage and
current settings for the instrument.

7.5.1 Channel Selection

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 NGL202, NGM202 or one channel for the NGL201,
NGM201.
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.
