error out

Error information.

The node produces this output 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.

error in

Error conditions that occur before this node runs.

Default: No error

datatype_icon

trigger coupling (DC)

Pass the trigger coupling. The driver uses this value to set the IviScope>>Trigger>>Trigger Coupling property. Defined Values:

IVISCOPE_VAL_AC The oscilloscope AC couples the trigger signal.
IVISCOPE_VAL_DC The oscilloscope DC couples the trigger signal.
IVISCOPE_VAL_LF_REJECT The oscilloscope filters out the low frequencies from the trigger signal.
IVISCOPE_VAL_HF_REJECT The oscilloscope filters out the high frequencies from the trigger signal.
IVISCOPE_VAL_NOISE_REJECT The oscilloscope filters out the noise from the trigger signal.

Default: IVISCOPE_VAL_DC

datatype_icon

instrument handle

The instrument handle that you obtain from the IviScope Initialize or IviScope Initialize With Options node. The handle identifies a particular instrument session.

instrument handle out

The instrument handle that you obtain from the IviScope Initialize or IviScope Initialize With Options node. The handle identifies a particular instrument session.

Where This Node Can Run:
