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 the instrument is equipped with, e.g. a
maximum of two channels for the NGL202, NGM202 or one channel for the NGL201,
NGM201.
You can address the channel by using the channel list command synax.
For more information, see
"Syntax for Channel List Commands"
Example: Selecting a channel
You can select a channel either with an
OUTput
parameter, or just by the channel
