Configures the aperture time on the specified channel(s).

connector_pane_image
datatype_icon

session in

Instrument session obtained from the Initialize With Channels node.

datatype_icon

channel name

Output channel(s) to which to apply this configuration value.

Channel Name Syntax

You can input the channel name with the following options:
  • A single channel, such a 0
  • A list of channels, such as 0,1 or 3,2,1,0.
  • A range of channels, such as 0-7 or 0:7.
spd-note-note
Note  

The order of channels in a list is important. NI-DCPower performs configurations of multiple output channels in the order the channels occur in the list.

datatype_icon

aperture time

Value that specifies the aperture time.

datatype_icon

aperture time units

Value that specifies the aperture time units.

Name Value Description
Seconds 1028 Specifies the aperture time in units of seconds.
Power Line Cycles 1029 Specifies the aperture time in power line cycles.
datatype_icon

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

datatype_icon

session out

Handle used to identify the session in all subsequent NI-DCPower node calls.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Supported Values

The supported values depend on both aperture time units and the specific device. In general, devices support discrete aperture time values. If you configure aperture time to an unsupported value, NI-DCPower coerces it up to the next supported value.
