Well, it seems no one knows this on the NI list, so maybe somebody here will. The attached VI has two analog inputs and one analog output. An external signal generator sine wave is connected to the first analog input. This is routed to the analog output which is physically connected to the second analog input. I want fresh data every time so I've set the vi to "No Regenerator". The problem is the AO only outputs one cycle of the sine wave before stopping, even though it keeps being supplied with more sine wave. It seems if there is any gap in data being provided to it, it just shuts down. Any ideas? Thanks, Ben Two AI and one AO - No Regeneration.vi

For an unusual application, we are trying to measure the time delay (~2msec) of the lower branch signal below by measuring the phase shift of the two analog outputs. However, it is not working because the merge block is waiting for both signals to arrive which effectively re-syncs the signals. I've tried to simply clone the Analog Output block, but Labview complains about that since the outputs are both on the same device. Anyone have a solution besides buying a second DAQ card? Ben
