Last Modified: September 7, 2018

Specifies the polarity of the external source signal.

instrument handle

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

Default: None

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

external polarity (Normal)

Specifies the polarity of the external source signal. The driver uses this value to set the IviRFSigGen>>Pulse Modulation>>Pulse Modulation External Polarity property. Defined Values: IVIRFSIGGEN_VAL_PULSE_MODULATION_EXTERNAL_POLARITY_NORMAL - The signal generator modulates the carrier signal with normal pulse polarity. Increasing the positive pulse voltage level results in higher RF level. IVIRFSIGGEN_VAL_PULSE_MODULATION_EXTERNAL_POLARITY_INVERSE - The signal generator modulates the carrier signal with inverted pulse polarity. Increasing the positive pulse voltage level results in lower RF level. Default Value: IVIRFSIGGEN_VAL_PULSE_MODULATION_EXTERNAL_POLARITY_NORMAL

instrument handle out

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

Default: None

error out

Error information.

The node produces this output according to standard error behavior.
