Analog Output and Counter Synchronization

[microscopist]

I have used the same PCI 6711 card to generate both an Analog Output square wave and a Counter square wave at 1228 Hz. From the scope the two trains of pulses are indeed at 1228 Hz, but they are not syncrhonizing. Attached is my VI. What could possibly the problem?

The simplest solution will be to configure the AO and CTR to start when an external trigger occurs (like another counter output).
