Advanced:Data Active Internal Route Delay Property

Short Name: DataActiveInternalRouteDelay

Property of niHSDIO

Configures the number of Sample clock cycles to delay the internal Data Active event. Internally routing a delayed version of this event is useful when you want to synchronize an acquisition trigger to the generation operation. Use this coarse delay together with the finer-resolution data delay to compensate for the round trip delay of data in stimulus/response operations.

You can configure the delayed Data Active event as the source for any acquisition trigger by manually entering DelayedDataActiveEvent as the source parameter in the appropriate niHSDIO Configure Trigger VI instance.

This property is applicable only in acquisition sessions and cannot be set as the trigger source when using STROBE as the external Sample clock.

Valid values for this property are 0 to 21 for the NI 6551/6552 and 0 to 29 for the NI 6555/6556. The units are in Sample clock cycles.

Note   This property is supported only for NI 655 x devices.
