Last Modified: October 24, 2017

Configures the interpolation method the oscilloscope uses when it cannot sample a voltage for a point in the waveform record.

interpolation

Value you can input for interpolation. Pass the interpolation method you want the oscilloscope to use when it cannot sample a voltage for a point in the waveform record. The driver sets the IviScope>>Acquisition>>Interpolation [I] property to this value.

Defined Values

IVISCOPE_VAL_NO_INTERPOLATION No interpolation
IVISCOPE_VAL_SINE_X sin(x)/x interpolation
IVISCOPE_VAL_LINEAR Linear interpolation

IVISCOPE_VAL_NO_INTERPOLATION

The oscilloscope does not interpolate any points in the waveform. Instead, the driver sets every element in the waveform array for which the oscilloscope cannot sample a value to an IEEE 754 - defined Nan (Not a Number) value.

Default: IVISCOPE_VAL_SINE_X

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.

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.
