Short Name: Compensate for Filter Group Delay

Property of niFgen

Adjusts for OSP filter group delay when aligning analog outputs and events in OSP mode. If you set this property to TRUE, event outputs align more closely with the analog output. The analog output also aligns more closely between two devices synchronized using NI-TClk.

Note  Group delay is the delay that occurs as a result of passing through a FIR filter. At a low I/Q rate, the group delay can become so large that some devices may not be able to align the events with the output. In this case, you must increase the I/Q rate or disable this property.
