Configures voltage levels for the pins you specify when not using levels sheets.

datatype_icon

voh

Output voltage above which the comparator on the pin driver interprets a logic high (H).

datatype_icon

vol

Output voltage below which the comparator on the pin driver interprets a logic low (L).

datatype_icon

session in

Instrument session obtained from the niDigital Initialize with Options node.

datatype_icon

channel list

List of channel names or pin names. Do not pass a mix of channel names and pin names.

An empty string denotes all digital pattern instrument channels.

Multisite 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.

datatype_icon

vih

Voltage that the instrument will apply to the input of the DUT when the test instrument drives a logic high (1).

datatype_icon

vil

Voltage that the instrument will apply to the input of the DUT when the pin driver drives a logic low (0).

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

vterm

Termination voltage the instrument applies during non-drive cycles when the termination mode is set to Vterm. The instrument applies the termination voltage through a 50 ohm parallel termination resistance.

datatype_icon

session out

Handle that identifies the session in all subsequent NI-Digital node calls.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Where This Node Can Run:

Desktop OS: Windows

FPGA: Not supported

Web Server: Not supported in VIs that run in a web application
