IviRFSigGen Configure Pulse External Trigger [PG] (G Dataflow)

Last Modified: September 7, 2018

Configures the triggering of the pulse generator within the RF signal generator. This node specifies the external trigger slope and the delay time for starting the pulse after the trigger pulse.

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 slope (Positive)

Specifies whether the event occurs on the rising or falling edge of the input signal. The driver uses this value to set the IviRFSigGen>>Pulse Generator>>Pule External Trigger Slope property. Defined Values: IVIRFSIGGEN_VAL_PULSE_EXTERNAL_TRIGGER_SLOPE_POSITIVE - Enables rising edge triggering. IVIRFSIGGEN_VAL_PULSE_EXTERNAL_TRIGGER_SLOPE_NEGATIVE - Enables falling edge triggering. Default Value: IVIRFSIGGEN_VAL_PULSE_EXTERNAL_TRIGGER_SLOPE_POSITIVE

datatype_icon

delay (0.0 Seconds)

Specifies the delay for starting the output pulse with respect to the trigger input. Units: Seconds Default Value: 0.0 Seconds

datatype_icon

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

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.
