niTuner_configAdvanceTrigger
Function Prototype
int niTuner_configAdvanceTrigger (int taskID, unsigned int signalSource, unsigned int signalType, unsigned int signalPolarity);
Purpose
This function configures the scan advance trigger input. The advance trigger tells the NI PXI-5600 downconverter to advance to the next frequency in the scan list. The ready signal is generated after the downconverter has settled to a frequency.
Parameters
| Name | Type | Description |
| taskID | int | The Task ID obtained from niTuner_init that identifies the session of a particular device. |
| signalSource | unsigned int | Identifies the source of the scan advance trigger signal. Hardware triggers are RTSI lines <0..6 >. Defined Values: Default Value: NITUNER_SIGNAL_SOFTWARE |
| signalType | unsigned int | Configures the RF downconverter to advance to the next frequency in the scan list when a pulse or a level signal is detected. Defined Values: Default Value: NITUNER_SIGNAL_PULSE If selected, the expected pulse must be in the direction of the signalPolarity. If selected, the level (while the PXI-5600 downconverter is not expected to trigger) will be in the direction of the signalPolarity. |
| signalPolarity | unsigned int | Configures the PXI-5600 downconverter to advance to the next frequency in the scan list on the specified polarity change. Defined Values: Default Value: NITUNER_SIGNAL_ACTIVE_LOW |
