Configure Active Load Levels
Configures IOL, IOH, and VCOM levels for the active load on the pins you specify.
The DUT sources or sinks current based on the level values. To enable active load, set the termination mode to Active Load. To disable active load, set the termination mode of the instrument to High Z or VTERM.
Inputs/Outputs
session in
Instrument session obtained from the niDigital Initialize with Optionsnode.
channel list
List of channel names or list of pins. Do not pass a mix of channel names and pin names.
An empty string denotes all digital pattern instrument channels.
Specify channel names using the form PXI1Slot3/0,2-3 or PXI1Slot3/0,PXI1Slot3/2-3, where PXI1Slot3 is the instrument resource name and 0, 2, 3 are channel names.
To specify channels from multiple instruments, use the form PXI1Slot3/0,PXI1Slot3/2-3,PXI1Slot4/2-3. The instruments must be in the same chassis.
Site Considerations and Syntax
Pin names and pin groups apply to all enabled sites, unless the pin name explicitly specifies the site. You can specify a pin in a specific site using the form siteN/pinName, where N is the site number. This node ignores pins that are not mapped to the digital pattern instrument.
iol
Maximum current that the DUT sinks while outputting a voltage below VCOM.
ioh
Maximum current that the DUT sources while outputting a voltage above VCOM.
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
vcom
Commutating voltage level at which the active load circuit switches between sourcing current and sinking current.
session out
Handle that identifies the session in all subsequent NI-Digital node calls.
error out
Error information.
The node produces this output according to standard error behavior.
