Details
When a channel that was previously off is turned on, the channel attributes are reset to their default
values (except the power state attribute).
Changing the output setting impacts the power consumption of the card. Channels with an off power
state consume less power. Before enabling power, the instrument verifies that power is available
before changing the state. If insufficient power capability exists, the command generates an error.
Consult the specific card documentation for information on a channel’s power usage characteristics,
including default state, possible warmup issues, especially for DAC channels, and effects on other
channels.
When a channel with an off power state is used in a scan, results are undefined. No error notification
is issued.
For switch, backplane, and digital I/O channels, there is no valid power state attribute. Setting the
power state on a specific channel generates an error.
On some cards for totalizer channels, setting the power state of a single channel can affect the power
state of other channels. If a single totalizer channel is turned on, all totalizer channels are reset to
their defaults.
Example
Sets the power state for DAC channel 10 on
the card in slot 1 to ON, assuming a 3750.
