stPMU Source Current
Enables the PMU capabilities on the channels specified in the channel list parameter and sources the current specified in the current level parameter while maintaining the voltage within the specified limits.
Inputs/Outputs

session in
Instrument session obtained from the Initialize Acquisition Sessionnode, the Initialize Generation Sessionnode, or the Initialize External Calibrationnode.

channel list
The channels you want to configure.
Specify multiple channels by using a channel list or a channel range. A channel list is a comma (,) separated sequence of channel names (for example, 0,2 specifies channels 0 and 2). A channel range is a lower bound channel followed by a hyphen (-) or colon (:) followed by an upper bound channel (for example, 0-2 specifies channels 0, 1, and 2).
Use PFI1 or PFI2 to specify a valid PFI channel. Use DDC_CLKOUT or STROBE to specify a valid clocking terminal. If you configure multiple channels with this parameter, all those channels have the same settings. Selecting no channels for this parameter returns an error.

current level
The current level, in amps (A), to source on the specified channel(s).

upper voltage limit
The maximum voltage limit, in volts (V), on the specified channel(s).

lower voltage limit
The minimum voltage limit, in volts (V), on the specified channel(s).

current range
The current range, in amps (A), used in the ensuing current measurement on the specified channel(s).
The PXIe-6555/6556 supports the following eight current range options:
- 32 mA
- 8 mA
- 2 mA
- 512 μA
- 128 μA
- 32 μA
- 8 μA
- 2 μA
If you choose a range other than one of these options, NI-HSDIO coerces the value up to the nearest range. NI-HSDIO also returns an error if you enter a value above 32 mA.
The default value is 0, but NI-HSDIO returns an error if you select a value less than or equal to 0.
Default value: 0

error in
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Default value: No error

session out
Handle that identifies the session in all subsequent node calls.
The session out parameter is obtained from the Initialize Acquisition Sessionnode or the Initialize Generation Sessionnode.

error out
Error information.
The node produces this output according to standard error behavior.
Committing your session
If you have not yet committed your session, calling this node implicitly commits your session. If you have already committed your session by calling a node such as the Commitnode, the Initiatenode, the Read Waveformnode, the Write Named Waveformnode, or the other nodes, this node will not commit your session again.
